If you're tired of struggling with a bloated belly every day and you feel like you've tried everything, then you should read this article.
That damn bloated belly. It just doesn't make sense. You've been going all out at the gym lately. Your diet has been absolutely clean. You're broke because you've stocked up on supplements to the max.
So why is your belly still bloated all the time? Why do you have to carry a baby bump around with you all day and why does your skin feel like a sponge soaked with water?
You can of course consult Dr. Google, but that won't get you very far. Skim the first few pages and you'll discover that there are about a million and one causes of a bloated belly and just as many "quick fixes" and "weird tricks" that are claimed to solve this problem for good.
You are skeptical and you should be. You may want to believe that a pill or a powder can give you a flat, defined stomach, but deep down you know that this is just wishful thinking.
And that's why it's good that you're here. In this article, you'll learn the real reasons you're constantly bloated and I'll show you 6 simple science-based strategies that can help you finally soothe and flatten your belly.
You are probably bloated for one of the following 5 reasons
In most cases, that unsightly flab around your midsection will be caused by one of 5 things.
1. too much body fat
What many people think is a chronically bloated midsection is actually just too much body fat.
First of all, bloat can come overnight, while body fat levels move up or down much more slowly.
For example, if you've ever woken up looking like a true well-toned Adonis, but by the end of the day looked more like a construction worker with a beer belly, that was bloat. Body fat doesn't accumulate that quickly - even if you binge eat.
The easiest way to tell if you are dealing with too much body fat or not is simply to measure your waist circumference at the level of your belly button every morning and every evening. If bloating is the culprit, then your readings will fluctuate wildly. If, on the other hand, body fat is the culprit, then the readings will be fairly consistent.
You should also know that your midsection will look and feel like it's bloated if you're a man with a body fat percentage over 15% or a woman with a body fat percentage over 25%.
The flat, defined stomach you want requires a body fat percentage of around 10% for men and 20% for women.
2. a lactose intolerance
Dairy products are packed with a type of sugar called lactose. In order for your body to use lactose, it has to be broken down by enzymes. The enzyme needed to break down lactose is called lactase.
The problem is that about 70% of the world's population cannot produce enough lactase, which means that they are unable to fully and properly digest lactose in dairy products.
When these undigested and partially digested sugars enter the large intestine, bacteria attack them and produce gases as a by-product. When these gases accumulate in the intestine, it swells up and voila - you are bloated.
3. irritable bowel syndrome or symptoms similar to irritable bowel syndrome
Irritable bowel syndrome is a disorder of the intestines that causes pain and discomfort in the abdominal area - and one of the symptoms is bloating.
There is a long list of physical and mental health issues that are known to contribute to IBS, but I'm going to focus on one in particular here:
A type of carbohydrate known as a FODMAP, which stands for fermentable oligo-, di-, mono-saccharides.
FODMAPs are found in grains such as wheat, rye and barley, beans, dairy products and many fruits and vegetables. They can cause bloating in a similar way to lactose: they are difficult to digest and some people cannot digest them properly, resulting in undigested food entering the large intestine where it becomes food for gas-producing bacteria.
4. a sodium-potassium imbalance
Increasing your sodium intake above the norm causes your body to retain more water (1). A good portion of this retained fluid will be under your skin, making it appear thicker and softer.
This is one of the reasons why you're likely to be significantly more bloated after an epic day of eating.
This probably isn't news to you, but you may not realize how easy it is to consume too much sodium and become bloated. A measly teaspoon of salt contains about 2.3 grams of sodium and it only takes a few extra teaspoons on top of your normal intake to make a noticeable shift in the amount of water stored.
This is the reason that many cases of chronic bloating can be "cured" simply by getting your sodium and potassium intake under control.
5. hormones
Hormones are often the bogeyman when it comes to fitness. You know, belly fat, plateaus in fat loss and muscle gain, irresistible cravings, slow metabolism, etc. - blame it on those pesky hormones that conspire to keep you fat, weak and unhappy.
Well, that's simply not true. People - including some self-proclaimed gurus - love to pick on the endocrine system (the system that produces hormones) because it's a good scapegoat.
This system is so large and complex that a little pseudoscientific talk is all that's necessary to get the layperson to reach for their wallet.
The reality, however, is this:
Hormones affect pretty much every physiological mechanism in your body, but when it comes to things like stagnant weight loss, slow muscle gain and unsightly belly fat, they're rarely the problem.
The real problem is usually just a misapplication of the basic fundamentals of weight loss and muscle building.
However, when it comes to bulking up, hormonal imbalances can be an important piece of the puzzle. The best demonstration of this is an experiment conducted during World War 2 that would never pass ethics committees today.
The purpose of this experiment, conducted under the direction of Dr. Ancel Keys and known as the Minnesota Starvation Experiment, was to study the physical and psychological effects of starvation and to develop an effective program to help starving prisoners of war return to a normal dietary regimen and metabolic function.
The experiment was conducted with 36 volunteers (conscientious objectors who preferred this experiment to serving on the front lines) and began with 12 weeks of hard labor and a maintenance calorie intake of about 3,200 kcal per day.
Next came the 6-month starvation phase of the experiment, which consisted of a reduction in calorie intake to around 1,500 kcal while maintaining physical labor. The scientists individually adjusted the subjects' diets with the aim of achieving a weight loss of around 25% at the end of the 6-month phase.
This starvation phase was followed by 20 weeks of metabolic rehabilitation, which consisted of restricted and unrestricted increases in calorie intake.
This study revealed a lot of fascinating facts, but I would like to focus on one particular observation at this point.
At the beginning of the experiment, subjects generally lost weight in a predictable and linear fashion, with weight loss of about 2 pounds per week.
After a while, however, the weight loss became strangely nonlinear. Sometimes the scale wouldn't move for weeks and then there would be a significant weight loss virtually overnight. As the researchers discovered, these were the effects of dramatic increases and decreases in water retention, not body fat.
This meant that these men lost fat even during the weeks when their weight did not change, but this was offset by corresponding water retention.
You may now be wondering what caused these spurts of water retention, which are also well known in bodybuilding circles. Well, some came about by chance for no apparent reason, but most followed an acute increase in calorie intake.
For example, halfway through the study, a 2,300 kcal meal was served to celebrate. The researchers noted that many of the men woke up several times the following night to urinate, and the next morning the men were several pounds lighter.
This raised the following question: What caused these men's bodies to retain large amounts of water and why did eating large amounts of food reverse this effect?
Well, the primary suspect was the hormone cortisol and subsequent research has proven this hypothesis. Studies show that a prolonged calorie deficit dramatically increases cortisol levels (2), which causes a whole range of adverse effects in the body, including increased water retention (3).
Basically, an increase in cortisol levels will also result in an increase in the amount of water your body stores, which will make you look bloated. And that's exactly what happened to the subjects in the Minnesota experiment. Feasting lowered cortisol levels (carbohydrates are particularly good at reducing cortisol levels, by the way (4)), which in turn caused rapid water excretion.
The bottom line is this: If you want to minimize potential bloat, make sure your cortisol levels aren't too high.
6 science-based ways to get rid of a bloated belly
Now that we know what the most common reasons for a bloated belly are, it's time to talk about what you can do about it. Figuring out what's causing your individual bloat can take some trial and error, but for most people the solution lies in one of the 6 tips below.
1. keep your chair moving
Before you start tinkering with your diet, make sure you're not suffering from constipation, as this will make a bloated belly worse (5).
Constipation can have a number of causes, but the cause most people have heard of - inadequate fiber intake - is rarely the reason (6). Ironically, increasing fiber intake in response to constipation can actually make it worse (7) and studies have shown that reducing fiber intake can help relieve constipation (8).
The point here is that you should just make sure you're eating enough fiber and if this can help you with your bowel movements, that's great.
Of course, laxatives can help you go to the toilet more regularly, but exercise (9) and magnesium supplementation are also two reliable ways to keep your stools moving.
2 Avoid soft drinks and other carbonated beverages
The math is simple. Bloating is exacerbated by two things: water retention and excessive amounts of gas in the digestive tract - and your soft drinks are made from water that has been mixed with carbon dioxide gas to make them fizzy, as well as sugar syrup. Carbonated drinks + your stomach = bloat
3. keep your sodium and potassium levels balanced
If your belly is bloated and you're not suffering from constipation or drinking carbonated drinks, you need to dig a little deeper to find relief for your bloated belly. And controlling your sodium and potassium intake is a good place to start.
Remember that a large increase in sodium intake can cause water retention and bloating. But you should also know that inadequate potassium intake can do the same (11).
The key here is to maintain a stable and adequate intake of both sodium and potassium. Official recommendations are 1.5 to 2.3 grams of sodium and 4.7 grams of potassium per day. (These amounts increase if you sweat a lot, as is the case with athletes. I personally consume about 3 to 4 grams of sodium and about 5 to 6 grams of potassium).
If you take a closer look at the sodium and potassium content of your diet, you'll probably find that you're eating too much sodium and not enough potassium.
Here are some simple ways to get the right intake of these two minerals:
- Avoid processed foods, breakfast meats and other types of processed meats like sausage and franks.
- Reduce the use of salt in cooking.
- Look at the labels on sauces and salad dressings and choose lower salt options.
- Include more potassium-rich foods such as beans, dark green leafy vegetables, bananas, potatoes, pumpkin, salmon and mushrooms in your diet.
4. lower your cortisol levels
Your body reacts to physical and mental stress by increasing cortisol production. This is necessary and healthy and is an integral part of the fight or flight response that has helped us survive since time immemorial.
However, the whole thing becomes a problem when cortisol levels remain chronically elevated. If you've been on a calorie deficit for too long, if you exercise too much or if you're dealing with abnormally high levels of physical or mental stress, chances are your cortisol levels have been too high for too long. And that means your body is retaining more water than it should.
Fortunately, there are some quick and easy ways to lower your cortisol levels and keep them in a healthy range:
- Don't starve yourself to death
- Avoid overtraining
- Develop a daily relaxation routine
- Forget low-carb diets
- Have occasional refeed days during a diet
- Do a detox week at the gym
- Make sure you get enough sleep
5. avoid foods that are known to cause digestive problems
So far we've looked at some pretty simple strategies to combat a bloated belly. Well, this one is a little more challenging. But the good news is that I'm not telling you that you have to swear off all foods that aren't considered part of a clean diet. This is just about some specific foods that we've talked about before: Dairy and FODMAPs.
As you know, these foods can cause bloating in many people and the first step to finding out if they are the cause of your problems is to eliminate them from your diet.
Here's a list of foods you should avoid to see how your body reacts:
- Grains such as wheat, barley and rye
- beans
- dairy products
- Onions and garlic
- artichokes
- Asparagus
- Vegetables such as broccoli, Brussels sprouts, cauliflower and other types of cabbage
- chocolate
- Fruit such as apples, apricots, blueberries, cherries, nectarines, peaches, plums, watermelon
- mushrooms
- avocados
- Sugar alcohols such as xylitol, sorbitol and mannitol
I know this is a long, frustrating list, but remember that this is only temporary - and even if it works, it doesn't mean you have to give up these foods forever.
Instead, you can use the approach used in testing for food intolerances and add these foods back into your diet one at a time while keeping a food diary. You will find that only a handful of these foods will cause bloating.
6. don't waste your time with natural diuretics
If this isn't the first article you've read on this topic, you've probably come across claims that certain foods and supplements can prevent a bloated belly and help you achieve the sexy flat stomach you've always wanted.
Examples include asparagus, nettle, celery, green leafy vegetables, hawthorn, bananas, olive oil, horsetail, green tea, parsley and many, many more.
Unfortunately, I have yet to find any scientific evidence that any food or supplement can reliably reduce bloat. Sure, potassium-rich foods like bananas, beans and vegetables can help if low potassium intake is the cause of your problems, but in this case it's not the food per se that helps, it's the potassium.
Alcohol is known to have a diuretic effect (12), but becoming a binge drinker is not really a viable strategy against a bloated belly. Caffeine also has mild diuretic effects, but scientific research shows that the fluid consumed with caffeine more than replaces any water excreted (13).
The bottom line is that no food or natural supplement will lead to a noticeable reduction in water retention. You will have to work a little harder for it.
The bottom line on bloated belly
I can understand if you are extremely frustrated with your bloated belly. Fortunately, there are some simple solutions. As long as your problems are not caused by a medical issue, here's what you need to do:
- Find out if it's just fat or actually a bloated belly.
- Eat enough fiber, exercise regularly and make sure you're getting enough magnesium in your diet.
- Reduce carbonated drinks.
- Make sure your sodium and potassium intake is balanced.
- Avoid excessive physical or mental stress.
- Reduce your FODMAP intake (if nothing else helps).
This will significantly reduce or eliminate your symptoms.

Since when did not getting enough sleep become something to brag about? "Hey, I only sleep 5 hours a night!" Congratulations. How many times can you hit yourself in the soft tissue with a hammer before training?
Not getting enough sleep doesn't make you a badass, but it certainly affects your efforts in the gym. While you may be able to "function just fine" on a few hours of sleep, too little sleep will still alter your results in terms of body recomposition.
The studies
In one study, the group that slept 8.5 hours per night lost more fat than the group that slept only 5.5 hours per night. In addition, the group that slept less lost significantly more muscle (60%) than the group that got a full 8.5 hours of sleep. This is another reason why body recomposition is more than "calories in vs. calories out".
Where do you think your recovery really comes from? Babies tend to do two things - eat and sleep a lot. Why? Because getting the body to grow requires an enormous amount of rest. So if you're not getting enough sleep, when are you going to give your body the extra time it needs to grow?
Relax, dammit!
Relaxing your mind and body at night can be a problem. Make sure your sleep-wake cycle, which is regulated by light and darkness, is functioning normally. When it's dark, your body releases more melatonin. When it is light, your body reduces the release of melatonin and increases the release of excitatory hormones.
The light you expose yourself to can interfere with the body's release of natural melatonin and delay falling asleep. Reduce laptop, TV and cell phone use in the evening and open the curtains in the morning so that your body can be awakened by natural sunlight. The morning sunlight will help to get your sleep-wake rhythm in order.
Additional help
If you have trouble winding down or relaxing at night, try a good ZMA product or another natural sleep-inducing supplement.
Tip: Autoregulate your breaks
A new study on resting between sets could change the way you train, especially if hypertrophy is your goal.
Source: https://www.t-nation.com/training/tip-auto-regulate-your-rest-periods
By Jorden Pagel
There's a lot that comes into play when building and executing a training plan when it comes to achieving your goals. Things like the exercises you'll perform, the load, the tempo and the number of reps and sets all play a role in whether or not a program will work. However, one of the most important factors is often overlooked: the rests between sets.
How long you rest will largely determine the effectiveness of your program. If your goal is to build strength and you don't rest long enough, you won't be able to perform your next set with maximum effort. And if your goal is to build muscle mass, you could compromise your muscle growth if you rest too long.
The conventional approach
There are certain predetermined rest intervals that most exercisers follow. Here is the conventional view.
Strength
Maximum strength can be defined as training at an intensity of 90% of your 1RM weight for < 4 repetitions. Based on the intensity at which you train and the energy systems used, the conventionally recommended rest period is somewhere between 2 and 5 minutes.
Hypertrophy (muscle growth)
It is always believed that shorter rest periods (30 to 90 seconds) are best for maximum muscle growth. However, recent studies suggest that this is not the case. A study by Henselmans and Schoenfeld found that there is no real scientific basis for the claim that shorter rest periods are better for mass gains.
According to Schoenfeld, "Based on current research, it appears that you can self-regulate your rest breaks, which allows you to put in the necessary effort on your next set without compromising your muscle gains.
Basically, they've found that because volume and tension are the two strongest facilitators of muscle growth, a reduction in rest periods can result in a reduction in the amount of weight you can move. And if resting a little longer allows you to increase volume and/or tension, then this will lead to greater gains.
So rest breaks for hypertrophy should vary from 1 to 3 minutes depending on the exercise performed and the amount of weight used.
Muscle endurance
The aim here is to increase resistance to fatigue. Endurance training is performed with light weights and a high number of repetitions (15 to 20 or more). To induce fatigue under these circumstances, the rest intervals must be short - generally less than one minute
Fat loss
Although your ability to lose fat is largely determined by your diet, the length of your rests between sets can also have an impact on your metabolic environment and your ability to burn fat. Many fat loss programs combine the above training methods. However, as the primary goal is not to produce maximum strength or muscle growth, conventional rest intervals are not normally used here.
If fat loss is the primary goal, then you want to drive the metabolic fire up as high as possible. To achieve this, rest intervals are generally limited to 30 seconds or less for less exhaustive exercises such as bodyweight exercises, kettlebell training or dumbbell training, while they can be up to 2 minutes for more intense multi-joint exercises.
Autoregulation & RPE
Autoregulation is the practice of adjusting your program (sets/reps/pause intervals) before or during your workout based on how you feel. In terms of rest intervals, these are timed based on how you feel, rather than adhering to predetermined rest times.
Despite the fancy name, autoregulating your break intervals is quite simple. Basically, you perform the next set when your heart rate returns to normal and you feel ready for the next set. This feeling will vary depending on what you are doing. Multi-joint exercises will require longer rests than isolation exercises.
The important thing here is that you estimate the length of your rests yourself rather than a set amount of time. You perform your next set when you're ready - not when you've finished checking your messages on Facebook.
A good way to gauge this feeling is to use the Rate of Perceived Exertion (RPE) scale. Here you rate the intensity of your exercise on a scale from 1 to 10, where 1 stands for no or little effort and 10 for failure due to exertion. The perceived exertion rate works well because it allows you to regulate your rest intervals based on how you feel. The same set can produce different levels of physical exhaustion on different days, and the perceived exhaustion rate lets you regulate your rest intervals based on where you are on the scale on a given day.
You'll have days in the gym where you feel great and you'll have days where you feel like a bag of garbage. Auto-regulation allows you to keep the volume of your workouts high by taking longer breaks when you need them.
Benefits
There are a number of benefits to auto-regulating your training, especially if your goal is maximum strength or muscle growth. An individual choice of your pause times will allow you to put in the maximum effort required for each set.
Let's take deadlifts with near maximal effort as an example. Your goal for a given day is to perform 3 sets of 3 reps with 90% of your 1RM weight and 3 to 4 minutes rest between sets. The first set goes well, but after the second set you feel exhausted. You realize that you will not be able to perform the third set with the current weight after only 4 minutes rest.
If your goal is maximum strength, what will you benefit more from: reducing the weight so that you can stay at the specified length of rest intervals or resting one minute longer to be able to perform the following set with the same weight? Obviously the extra minute of rest.
The same goes for building muscle. Volume is the primary driving force for muscle growth, so resting 30 or 60 seconds longer will have many more benefits if it allows you to maintain a higher volume.
Disadvantages
The biggest disadvantage of auto-regulating your rest intervals is that it requires an honest assessment of your training. You can't just rest as long as you want - you need to be honest with yourself about how long you NEED to rest.
Auto-regulation is also probably not the best way to regulate your rest intervals during a fat loss program, as the design of many of these programs requires you to complete your sets under a high level of exhaustion to increase calorie expenditure.

Tip: Evaluate your bench press technique
The form of your bench press exercises could be increasing your risk of injury. It's time to re-evaluate your technique.
Source: https://www.t-nation.com/training/tip-assess-your-bench-press-technique
By Joel Seedman, PhD
Choose any variation of the bench press such as flat bench press, incline bench press or bench press on a reverse incline bench. Use dumbbells held in a neutral position (palms facing each other) and keep your elbows close to your sides.
Instructions
Increase the weight and find out how much you can move. Write this weight down. You should be able to move at least 80% of your normal barbell bench press weight when you add up the weight of the two dumbbells. So if you typically bench press 100 kilos with a barbell, you should be able to move 40 kilos of dumbbells in a similar way.
The position with the elbows held close to the body may feel strange at first, but it represents the correct mechanics for any bench press variation, regardless of whether it is performed with a barbell, dumbbells or any other loading mechanism.
Your score
If you fail this test, start incorporating dumbbell bench presses into your training. More importantly, during all pressing exercises, pull your shoulder blades down and back and pull your elbows towards your body by activating your latissimus.
A good dose of stabilization training for the upper back and shoulders would also be appropriate. As most individuals lack sufficient strength in the latissimus and stability and motor control in their upper torso, this position often feels quite weak.
In fact, it is not uncommon to see exercisers bench pressing 150 kilos or more but struggling with 50 kilo dumbbells. This would suggest that they have become very efficient with faulty movement mechanics - which is a common problem even among advanced exercisers.
Aside from requiring the exerciser to stabilize each side separately, the dumbbell version limits the exerciser more tightly in the range of correct position while reducing their ability to use compensatory movement patterns and momentum, which many exercisers have relied on over the years.
Tip: Use 3 seconds of lowering for your biceps
Want to make your arms grow? Extend the eccentric phase of your biceps exercises.
Source: https://www.t-nation.com/training/tip-use-3-second-descents-for-biceps
By John Meadows
Three-second lowering works better for certain exercises than others, depending on the muscle group being trained. For biceps, this method works for almost everything. Here are some general guidelines for using this technique in your bicep workout.
3 second lowering for biceps
Don't overdo it! As you probably know, the eccentric or lowering phase of the movement is the part where a lot of muscle damage is generated. Combine this with the fact that the biceps are quite a small muscle group and you get the perfect recipe for trouble if you use this technique on all your sets.
Guidelines:
- Use 3 seconds of lowering on one exercise (3 to 4 sets) per training session.
- Use 3 seconds of lowering on one set of each exercise if you perform multiple exercises for your biceps during a training session (still only 3 to 4 sets).
- The best way to use this technique is during basic exercises such as barbell or dumbbell curls at the end of a training session, when you have already achieved a strong bicep pump. You won't be able to use a lot of weight, but you'll feel the exercise like never before.

Men should know their oestrogen levels
Every adult man should know what his oestrogen levels are. Your health, your appearance, your emotional well-being and your ability to conceive may depend on it. In fact, your life could depend on knowing if your estrogen levels are too high or too low.
Oestrogen and testosterone are closely linked
Testosterone gets most of the attention in men, while estrogen gets most of the attention in women, but estrogen is just as important to men as testosterone in many ways. And even though these two hormones are considered the yin and yang of human sexual behavior and development, they are very similar on a molecular level.
You could put these two molecules right next to each other and they would look virtually identical except for the fact that testosterone has an extra carbon atom. And this similarity is one reason why some men have high estrogen levels. Because the testosterone molecule is so similar to oestrogen on a molecular level, it is very easy for the aromatase enzyme to separate the extra carbon atom and convert testosterone into oestrogen.
In principle, this is a good thing, as men also need a certain amount of oestrogen. Not only does estrogen have myriad effects on your health, but it is also part of an elegant feedback system that signals the testes via the pituitary gland to reduce testosterone production when estrogen levels get too high. In this way, this system ensures that the right amounts of testosterone and oestrogen are always circulating in the body.
Sometimes, however, too much testosterone is converted into oestrogen. Combined with the low levels of oestrogen produced in the testes, adrenal glands, brain and adipose tissue, this can cause a hormonal maelstrom of problems. The feedback loop kinks, estrogen levels remain continuously elevated and this signals the testes to produce less testosterone.
However, there are plenty of other ways in which excessive increases in testosterone levels can occur, and although not often talked about, low estrogen levels can sometimes be even more of a problem than high estrogen levels. Ultimately, estrogen levels should always be in the hormonal comfort zone - not too high, not too low, but just in the right range.
What problems can too high oestrogen levels cause?
As soon as oestrogen levels rise uncontrollably, the risk of degenerative diseases skyrockets. The risk of stroke increases. The risk of type II diabetes increases. Emotional disorders occur more frequently. The risk of prostate cancer increases.
Erectile function suffers. Waist circumference increases. It becomes harder to build muscle. And, worst of all, high oestrogen levels significantly increase the overall risk of death.
When scientists studied the estrogen levels of 501 men with chronic heart failure, men with normal estradiol levels (the "most potent" form of estrogen) in the range of 21.80 pg/mL to 30.11 pg/mL had the fewest deaths over the three-year study period. Men with the highest levels (above 37.99) had 133% more deaths during the same period. However, the men with the lowest oestrogen levels (below 12.9) were even worse off, with 317% more deaths in this group.
So estrogen certainly plays an important role in heart health, in addition to its role in many other body systems.
Signs of high estrogen levels include:
- An increased amount of fat in the abdominal area
- A loss of muscle mass
- Low libido, reduced erectile function
- Fatigue
- An increase in fatty tissue in the nipple area
- Depression and emotional disorders
- Lower urinary tract symptoms associated with benign prostate enlargement
Signs of low estrogen levels include:
- Usable erections but mediocre orgasms
- Joint discomfort
- Fatigue and depression
- Reduced emotions
- A possible weakening of the adrenal glands
- Anxiety
- Excessive jealousy
- Low blood pressure
- Excessive urge to urinate
Testing oestrogen levels
Regardless of age, it is in every man's interest to ensure that his estrogen levels are in the green zone. It is important to establish a baseline estrogen level against which to compare levels in subsequent years.
Here is a list of average estrogen levels by age from a study published in the journal Clinical Endocrinology:
- Age 2-29 years: 28.0 pg/mL
- Age 30-39 years: 25.7 pg/ml
- Age 40-49 years: 24.7 pg/ml
- Age 50-59 years: 22.1 pg/ml
- Age 60-69 years: 21.5 pg/ml
- Age 70-80 years: 21.9 pg/ml
There are different possible ways to accurately test estrogen levels - via a 24-hour urine test or via a blood test, with the blood test being the simpler. Saliva tests are now also available, which can be carried out without a doctor's visit.
In the case of a blood test, the more sensitive test for men should be used rather than the standard test, which is intended for women. In addition, some laboratories use immunoassay techniques to test blood samples, which have a variability rate of up to 53% compared to other methods. Such inaccurate results could lead to problems being treated that do not actually exist. For example, if supposedly high estrogen levels are treated when in fact they are in the normal range, the consequences can be catastrophic. Liquid chromatography or a mass spectrometer test should be used instead, as these tests are more accurate.
To complicate matters further, sex hormone binding globulin (SHBG) also plays a role in estrogen levels. As the name suggests, SHBG binds a certain percentage of sex hormones, including testosterone and oestrogen, making them inaccessible to the body.
With increasing age, SHBG levels rise and bind more hormones. As a result, even though estrogen levels may appear normal, free estrogen levels may be too low. Ideally, SHBG and estrogen blood levels should be in the mid-normal range to provide an accurate snapshot of the estrogen situation in the body.
What can cause high estrogen levels?
1 - Too much body fat
Fat contains the aromatase enzyme that converts testosterone into oestrogen. So the fatter you get, the more testosterone is converted into oestrogen, making you even fatter. This is a vicious cycle and the only way to break out of it is to get and stay lean.
2 - The natural ageing process
The older you get, the more aromatase enzyme your body produces and the higher your oestrogen levels will rise. This is the reason why the breasts of old men on the beach are often indistinguishable from the breasts of their old wives.
Of course, this age and oestrogen thing is not quite so clear-cut. Since SHBG levels also increase with age, which can cause some of the extra estrogen to be bound, one could also assume that old men have less free estrogen. In addition, age also brings with it a reduction in testosterone production, which may also lead to less oestrogen, as there is less starting material available to be converted into oestrogen.
These phenomena may partly explain why so many men with heart problems have either too high or too low estrogen levels.
3 - A faulty feedback mechanism
When estrogen levels are too high, this signals the testes via the pituitary gland to temporarily stop producing testosterone. However, if estrogen levels are continuously elevated, this can override the system and send the wrong signal to the testes to take a long vacation. This can lead to even higher estrogen levels.
4 - Testosterone replacement therapy
Millions of men are undergoing testosterone replacement therapy to revitalize their bodies and revive their flagging libidos. Unfortunately, many doctors have not done their homework. Injecting men - especially obese men - with too much testosterone can result in an unwanted amount of it being converted to estrogen. These elevated levels need to be addressed either by adjusting the testosterone dosage or by using an aromatase inhibitor.
5 - An impaired cytochrome P450 enzyme system
The P450 system is the system where most active drug ingredients end up. In other words, the vast majority of drugs, chemicals or supplements you take are processed and eliminated by the P450 system. This system is like a chemical recycling station where chemicals are broken down, repackaged and either reused or excreted.
The same system also eliminates estrogen from the body. However, certain things can interfere with this system. Too much alcohol can be a problem, as can obesity or a zinc deficiency. You may also be consuming foods or medications or supplements such as grapefruit juice or ginkgo biloba that interfere with the efficiency of the P450 system.
6 - Xenoestrogens
These are chemicals in our environment that mimic the effects of estrogen. These chemicals - mainly heavy metals, synthetic chemicals like DES and DDT, and industrial chemicals like phthalates are increasing in volume and accumulating in more body tissues with each passing year.
These chemicals can be found in food, adhesives, fire retardants, solvents, drinking water, perfumes, waxes, household cleaners, lubricants, etc.
Although we do not know the exact extent of the damage caused by these chemicals, there have been widespread reports of biological abnormalities in humans and animals (mutations, hermaphroditic sexual organs, reduced fertility, etc.) in recent decades.
In 1992, a team of reproductive specialists from Copenhagen reported that the average sperm count in industrialized countries has dropped by 50% since 1938 (which means you're probably only half the man your grandfather was).
What's more, there's plenty of evidence that these chemicals are a part of all of us. Scientists have found that 75% of samples taken from 400 adults contained significant levels of industrial xenoestrogens, while 98.3% of samples were found to contain DHT and its derivatives. To make matters worse, certain xenoestrogens appear to interact synergistically, amplifying their effects.
7 - Phytoestrogens
While xenoestrogens are man-made monstrosities, phytoestrogens are found in plants. Xenoestrogens accumulate in fatty tissue, while phytoestrogens are metabolized and soon excreted from the body. They are therefore not nearly as big a problem as xenoestrogens.
Nevertheless, you should not have too many phytoestrogens in your body, as they are similar to oestrogen on a molecular level and can also act like oestrogen. Phytoestrogens are found in various foods and probably most commonly in soy protein.
8 - Alcohol and marijuana
Yes, recreational drugs can also lead to elevated estrogen levels.
What can lead to low estrogen levels?
There are not many things that can cause low estrogen levels in men. One is advanced age with its accompanying low testosterone levels and elevated SHBG levels. This can be treated with testosterone replacement therapy.
Another reason for low estrogen levels is overuse of estrogen blockers and aromatase inhibitors. These drugs are prescribed by doctors and either prevent testosterone from being converted to estrogen or prevent estrogen from binding to the estrogen receptors in cells.
Of course, a man with low oestrogen levels may also be suffering from an as yet undiagnosed disease that is responsible for these low levels.
What can you do about high oestrogen levels?
1 - Nutrition
Many vegetables contain indole-3-carbinol, which reduces the effects of estrogen. These chemicals are found in useful amounts in broccoli, cauliflower and cabbage.
Calcium D-glutarate is also an effective fighter against estrogen, as it eliminates estrogen from the body before the body reabsorbs it. This active ingredient is found in grapefruit, apples, oranges and the aforementioned vegetables rich in indoles.
However, these fruits and vegetables alone cannot bring estrogen levels that have gotten out of control back into balance. At best, they can be seen as aids that can help to shift the amount of oestrogen metabolites in the right direction. In turn, you should avoid foods such as soy that can shift the amount of oestrogen metabolites in the other direction.
2 - Supplements
Because estrogen is such a big issue, the supplement industry has spent a lot of time researching this topic. Here are a few nutrients and compounds that seem to be the most effective when it comes to normalizing estrogen levels:
- Boron (reduces levels of free estrogen)
- Curcumin reduces the effect of the aromatase enzyme
- Fish oil - especially DHA - which reduces the number of oestrogen receptors
- Green tea extract appears to inhibit the aromatase enzyme
- Resveratrol reduces the activity of the aromatase enzyme
- Zinc reduces the activity of oestrogen receptors
3 - Pharmaceutical interventions
Aromatase inhibitors impair the ability of the aromatase enzyme to convert testosterone into estrogen.
There are two classes of aromatase inhibitors. The first class is known as "suicide inhibitors", which includes the active ingredient exemestane. These should be avoided as they are extremely potent and can easily reduce oestrogen levels too much. The second class is the class of so-called competitive inhibitors such as anastrozole and letrozole. Letrozole should probably be avoided as it is very potent and can easily be an overkill for correcting moderately elevated oestrogen levels.
This leaves the moderately effective anastrozole aka Arimidex, which is sufficient to significantly reduce oestrogen levels. This active ingredient should only be used if symptoms of increased oestrogen levels are present and dietary interventions and supplements have not helped. Of course, this active ingredient should only be used under medical supervision.
However, most men do not need an aromatase inhibitor as long as they are not undergoing testosterone replacement therapy and too much of the testosterone used is converted to oestrogen.
4 - Reduction of xenoestrogens
To significantly rid your environment of xenoestrogens, you would probably have to move to the woods and feed on organically grown mung bean sprouts. Apart from that, however, there are things you can do to make your life less estrogen-rich.
If you're meticulous, you can try to avoid the following chemicals:
- Alkylphenol
- Atrazine (a weedkiller)
- 4-Methylbenzylidene camphor (4-MBC) (used in sunscreen products)
- Butylated hydroxyanisole / BHA (a food preservative)
- Chlorine and chlorine by-products
- Dichlorodiphenyldichloroethylene
- DEHP (used to make PVC elastic)
- Dieldrin (an insecticide)
- DDT (an insecticide)
- Endosulfan (an insecticide)
- Erythrosine / FD&C Red No. 3
- Ethinyl estradiol (combined oral contraceptive pill)
- Heptachlor (an insecticide)
- Lindane / hexachlorocyclohexane (an insecticide)
- Metalloestrogens (a class of inorganic xenoestrogens)
- Methoxychlor (an insecticide)
- Nonylphenol and its derivatives
- Pentachlorophenol (a biocide and wood preservative)
- Polychlorinated biphenyls / PCBs (found in electrical oils, lubricants, adhesives and paint)
- Phenosulfothiazine (a red dye)
- Phthalates (plasticizers)
- Propyl gallate
- Parabens (methylparaben, ethylparaben, propylparaben and butylparaben, which are often used as preservatives in personal care products)
Checking every label to see if the product contains one or more of the aforementioned chemicals can easily drive you mad. To make your life a little easier, you can do the following things whenever possible:
- Buy organic produce
- Store food in glass containers instead of plastic containers
- Remove plastic wrap before heating food in the microwave
- Use natural detergents and household cleaning products
- Use all-natural personal care products
- Avoid plastic whenever possible and don't drink from water bottles that have been in the sun for a long time
5 - Adjust your lifestyle
Your problems with estrogen may be related to drinking too much or too often, or smoking marijuana too often or too much. The simple solution to this is moderation. If you weigh too much (which in itself can increase estrogen levels), then do the obvious.
Take control of your estrogen levels
- Get your estrogen levels tested
- If your levels are normal, then use them as a reference for the following years.
- If the levels are too high, check if you have symptoms of high estrogen levels. If the levels are too low, check if you have symptoms of low estrogen levels.
- Address the problem using the solutions described above including lifestyle changes, dietary changes, supplements, avoidance of xenoestrogens and phytoestrogens, and medication under medical supervision.

High blood sugar levels occur when the body cannot efficiently transport sugar from the blood into the cells. If uncontrolled, this can lead to diabetes.
A 2012 study reported that 12 to 14% of all US adults suffer from type 2 diabetes, while 37 to 38% were classified as prediabetic (1). This means that approximately 50% of all US adults have diabetes or prediabetes.
Here are 15 natural ways to lower blood sugar levels and prevent prediabetes or diabetes from developing:
1. Exercise regularly
Regular exercise can help you lose weight and improve your insulin sensitivity. Increased insulin sensitivity means that your cells are better able to use the sugar in your bloodstream. Exercise also helps your muscles to use blood sugar as an energy source for muscle contractions.
If you have problems with blood sugar control, then you should check your blood sugar levels regularly. This will help you learn how to respond to different activities and prevent your blood sugar levels from rising or falling too much (2).
Good forms of exercise for this purpose include training with weights, fast walking, running, cycling, dancing, hiking, swimming, etc.
2. control your carbohydrate intake
Your body breaks down carbohydrates into sugar (mainly glucose) and insulin transports this sugar into the cells. If you eat too many carbohydrates or have problems with insulin function, this process will not work properly and blood sugar levels will rise. However, there are some things you can do to prevent this.
The American Diabetes Association (ADA) recommends controlling carbohydrate intake by counting your carbohydrates or using another method to control carbohydrate intake (3). Some studies have found that these methods can help you plan meals appropriately, which can improve blood sugar control (4, 5).
Many studies also show that a low-carbohydrate diet can lower blood sugar levels and prevent a sharp rise in blood sugar levels (6, 7, 8, 9). In addition, a low-carb diet can help control blood sugar levels in the long term (10).
3. increase your fiber intake
Fiber slows down the digestion of carbohydrates and the absorption of sugar. For this reason, it promotes a slower rise in blood sugar levels.
In addition, the type of fiber you consume may also play a role. There are two primary types of fiber: soluble and insoluble fiber. While both are important, soluble fiber in particular has been shown to lower blood sugar levels (11, 12, 13).
In addition, a high-fiber diet can help to better control type 1 diabetes by improving blood glucose control and preventing low blood glucose levels (13, 14).
Foods rich in fiber include vegetables, fruits, legumes and whole grains. The recommended daily intake for fiber is about 25 grams for women and 38 grams for men. This corresponds to about 14 grams of fiber per 1,000 kcal (15).
4. drink water and make sure you are well hydrated
Drinking enough water could help you keep your blood sugar levels within healthy limits. In addition to preventing dehydration, adequate hydration helps your kidneys excrete excess blood sugar through urine.
An observational study showed that those who drank more water had a lower risk of developing high blood sugar levels (16). Drinking sufficient amounts of water regularly rehydrates the blood, lowers blood sugar levels and reduces the risk of diabetes (16, 17, 18, 19).
Keep in mind that water and other calorie-free drinks are best. Sugar-sweetened drinks raise blood sugar levels, promote weight gain and increase the risk of diabetes (20, 21).
5. introduce portion control
Healthy portion control helps regulate calorie intake and can contribute to weight loss (22, 23, 24). In addition, controlling body weight promotes healthy blood sugar levels and can also reduce the risk of developing type 2 diabetes (22, 23, 25, 26, 27, 28).
Monitoring your portion sizes will also help you to reduce your calorie intake and, as a result, lower your blood sugar levels (23, 24).
Here are some useful tips for portion control:
- Measure and weigh your portions
- Use smaller plates
- Avoid all-you-can-eat restaurants
- Pay attention to food labels and check portion sizes
- Keep a food diary
- Eat slowly.
6. choose foods with a low glycemic index
The glycemic index was developed to determine the body's blood sugar response to foods containing carbohydrates (29). Both the amount and type of carbohydrate determine how a food affects blood glucose levels (30, 31).
It has been shown that long-term blood glucose levels can be lowered with type 1 and type 2 index (32, 33). However, although the glycemic index of foods is important, the amount of carbohydrate consumed also plays a role (34, 35).
Foods with a low glycemic index include seafood, meat, eggs, oats, rye, beans, lentils, legumes, sweet potatoes. Corn, yams, most fruits and non-starchy vegetables.
7. control your stress levels
Stress can affect your blood sugar levels (36, 37). Hormones such as glucagon and cortisol are released during stress. These hormones can cause blood sugar levels to rise (38, 39).
One study showed that exercise, relaxation and meditation significantly reduced stress and lowered blood sugar levels in students (40). Exercise and relaxation methods such as yoga and conscious stress reduction can also help to correct problems with insulin secretion in chronic diabetes (40, 41, 42, 43, 44).
8. monitor your blood glucose levels
"What gets measured gets controlled." Measuring and monitoring blood glucose levels can also help you control them.
Monitoring your blood glucose levels will help you determine if you need to make adjustments to your meals or medication (31). It will also help you to find out how your body reacts to certain foods (45, 46).
Try to measure your blood sugar levels every day and keep a record of them.
9. make sure you get enough good sleep
Getting enough sleep is essential for good health (47). Poor sleep habits and a lack of rest and recovery can negatively affect blood glucose levels and insulin sensitivity, as well as increase appetite and promote weight gain (48, 49).
Sleep deprivation reduces the release of endogenous growth hormone and increases cortisol levels. Both play an important role in the control of blood glucose levels (47, 50, 51).
Good sleep is about both quality and quantity. It's best to get a sufficient amount of good sleep each night (49).
10. eat foods rich in chromium and magnesium
High blood sugar levels and diabetes have also been linked to certain micronutrient deficiencies (51, 52). Examples of such deficiencies include the minerals chromium and magnesium.
Chromium is involved in carbohydrate and fat metabolism. It also helps control blood glucose levels and a deficiency of chromium may increase the risk of carbohydrate intolerance (53, 54, 55). However, the underlying mechanisms are not fully understood. In addition, studies have come to different conclusions.
Two studies conducted with diabetic patients showed that chromium had positive effects on long-term blood glucose control, while another study found no benefits (55, 56, 57).
Chromium-rich foods include egg yolks, whole grains, cereals rich in bran, coffee, nuts, green beans, broccoli and meat.
Magnesium has also been shown to have positive effects on blood sugar levels. In addition, a magnesium deficiency has been linked to a higher risk of developing diabetes (31, 58, 59).
One study found that participants with the highest magnesium intake had a 47% lower risk of developing diabetes (60). However, if you already consume enough magnesium-rich foods, then magnesium supplements are unlikely to provide any additional benefits (61).
Magnesium-rich foods include green leafy vegetables, whole grains, fish, dark chocolate, bananas, avocados and beans.
11 Try apple cider vinegar
Apple cider vinegar can have many health benefits. It promotes lower fasting blood sugar levels, which may be due to a reduction in glucose production by the liver or increased utilization of blood sugar by cells (62, 63, 64).
In addition, studies show that vinegar can significantly affect the body's response to sugar and improve insulin sensitivity (63, 65, 66, 67, 68, 69).
To incorporate apple cider vinegar into your diet, you can add it to salad dressings or mix 2 teaspoons with 250 ml of water.
12. experiment with cinnamon extract
Cinnamon is known for its numerous health benefits. For example, it has been shown to improve insulin sensitivity by reducing insulin resistance at the cellular level (70, 71). Studies also show that cinnamon can lower blood sugar levels by up to 29% (72, 73, 74).
Cinnamon slows down the breakdown of carbohydrates in the digestive tract, which reduces the increase in blood sugar levels after a meal (75, 75). Cinnamon works in a similar way to insulin, albeit at a much slower rate (77).
An effective dose is between 1 and 6 grams of cinnamon per day, which is equivalent to 0.5 to 2 teaspoons of cinnamon (78). A higher intake is not recommended, as too much cinnamon can be harmful, especially cassia cinnamon.
13 Try berberine
Berberine is the active compound in a Chinese medicinal plant that has been used for thousands of years to treat diabetes. Berberine has been shown to help lower blood sugar levels and increase the breakdown of carbohydrates for the purpose of energizing the body (79, 80, 81).
In addition, berberine may be as effective as some blood glucose-lowering drugs. This makes berberine one of the most effective supplements for people suffering from diabetes or prediabetes (79, 82).
However, many of the mechanisms underlying these effects of berberine are not yet known (81, 83). In addition, berberine may have some side effects. Diarrhea, flatulence and abdominal pain have been reported (84).
A common dosage is 1,500 mg per day, which is usually divided into 3 single doses of 500 mg taken before meals.
14. eat Fenugreek (Fenugreek) seeds
Fenugreek seeds are an excellent source of fiber that can also help control blood sugar levels.
Many studies have shown that fenugreek can effectively lower blood sugar levels in diabetics. It also helps to lower fasting blood sugar levels and improve glucose tolerance (85, 86, 87, 88).
Although it may not be as popular, fenugreek can easily be added to baked goods to help manage diabetes. Fenugreek can also be used to make flour or brewed as a tea (89).
Fenugreek seeds are considered one of the safest medicinal herbs for diabetes (87, 88). The recommended dosage is 2 to 5 grams of fenugreek seeds per day.
15 Lose some weight
It goes without saying that maintaining a healthy weight will help you improve your health and avoid future health problems. Good weight control promotes healthy blood sugar levels and has been shown to reduce the risk of diabetes.
Even a 7% reduction in body weight can reduce the risk of diabetes by up to 58% and weight reduction appears to work even better than medication in this regard (90). What's more, this reduced risk can be maintained over the years (91, 92, 93).
You should pay particular attention to your waistline, as waist circumference is probably the most important weight-related factor in estimating your risk of diabetes. A waist circumference of 89 centimeters or more in women and a waist circumference of 101 centimeters or more in men are associated with an increased risk of developing insulin resistance, high blood sugar levels and type 2 diabetes (94). A healthy waist circumference may be even more important than overall weight (94).
Conclusion
It is always advisable to discuss major lifestyle changes or the use of new supplements with your doctor. This is especially important if you have problems with blood sugar control or if you are using medication to lower blood sugar levels.
If you are diabetic or have problems with blood sugar control, you should start doing something about it as soon as possible.

Pineapple is one of the most popular tropical fruits that contains an enzyme known as bromelain. Bromelain has become a widely studied compound in the scientific field due to its impressive health benefits.
What is bromelain?
Bromelain is a compound made up of proteases and is found in the pineapple fruit. While bromelain may be best known for its ability to aid in digestion and the breakdown of proteins, its potential uses far exceed these functions. Bromelain has much more to offer and the good news is that it is also available as a supplement that can be used in the treatment of numerous diseases.
The history of bromelain is closely linked to the pineapple, as it is the only known good source of this group of enzymes. Bromelain was discovered in 1891 by the chemist Vincente Marcano and subsequently studied further by another chemist named Russell Henry Chittenden. Bromelain was initially named bromelin and was described as a "proteolytic ferment of pineapple juice". The first known primary source of bromelain was the pineapple fruit, before it was later discovered that the ripe pineapple stem had higher levels of bromelain (2).
During the years following its discovery, the production of bromelain has continued to increase. Its commercial success has led manufacturers to develop faster extraction techniques for large-scale production. Today, bromelain supplements are used for numerous health purposes.
It has been observed that the timing of ingestion is important for the desired effect. Taken after a meal, for example, bromelain can improve digestion and the absorption of nutrients, while when taken on an empty stomach it can help to reduce inflammation (3).
Where does bromelain come from?
The only notable source of bromelain is the pineapple plant. The enzyme is usually extracted from either the stem of the plant or young pineapple fruit, although other parts of the plant also contain small amounts of bromelain. There are no other fruits that contain larger amounts of this compound.
There are two types of bromelain, depending on which part of the plant the bromelain was extracted from (4):
- Tight bromelain: This is the type of bromelain that is widely available on the market, as extraction is cheaper and the pineapple stem is ultimately a waste product. The extraction is done by centrifugation, ultrafiltration or freeze-drying. If bromelain is used in mainstream products, it is most likely of this type.
- Fruit bromelain: Studies suggest that fruit bromelain has a weaker digestive effect but a better proteolytic (protein-breaking down) effect than strain bromelain. In contrast to stem bromelain, fruit bromelain is rarely used due to its limited availability.
Potential health benefits of bromelain
As a protease enzyme, the primary benefit of bromelain is that it can improve protein absorption. However, bromelain is also commonly used to support healing and as an adjunct to the treatment of numerous diseases. For example, if you suffer from chronic inflammation or sports injuries, you might consider using bromelain supplements to help your body recover and recuperate.
Other potential benefits of bromelain supplements include:
Bromelain can reduce inflammation and swelling
Bromelain can help relieve symptoms of osteoarthritis and rheumatism. It is also used to support the healing of strains and sprains as it can reduce swelling and promote tissue healing. People taking arthritis medication might consider either switching to bromelain as a natural alternative or using it as a supportive treatment (5).
Bromelain can improve the function of the immune system
Studies have shown that bromelain can promote healthy immune system function by regulating numerous pro-inflammatory proteins during periods of cellular stress (6).
Acceleration of wound healing
It has been observed that the use of bromelain after surgery can promote soft tissue healing and reduce bruising. Patients who had taken bromelain experienced faster wound healing compared to subjects who had only used a placebo (7).
Bromelain can reduce the symptoms of sinusitis
Sinusitis is an inflammation of the inner mucous membranes of the sinus cavity, usually caused by infections or allergies. Bromelain is known to relieve symptoms of sinusitis (8). Together with quercetin, bromelain can help relieve sinus inflammation, with quercetin acting as an antihistamine (9).
Bromelain promotes blood circulation
Bromelain may help to promote healthy blood flow by reducing platelet aggregation in the veins and reducing the risk of blood clotting. This could reduce the risk of atherosclerosis and other cardiovascular diseases (10).
Bromelain could relieve menstrual cramps
There are claims that bromelain may help to induce menstruation by relaxing the tissues of the uterus. This could increase blood flow and is also said to help prevent menstrual cramps (11).
What can bromelain be used for?
Due to the impressive components of bromelain, it is not surprising that it is used to treat or reduce the severity of disease symptoms. Although it is usually recommended for patients who have undergone surgery or suffer from chronic sinusitis, bromelain can also be used for many other purposes. These include (12):
Bromelain can be applied to the skin for burns
Studies suggest that bromelain can help remove dead skin cells from third-degree burns and that it can help heal first- and second-degree burns. For severe burns, bromelain should only be used on the skin under medical supervision.
Bromelain can relieve indigestion and heartburn
Bromelain is known to help reduce indigestion and a bloated feeling, especially when taken in combination with other enzymes.
Bromelain can relieve discomfort from insect bites
Applying bromelain directly to insect bites can relieve inflammation and other discomfort.
Bromelain can be used as a meat tenderizer
Pineapple is also used in cooking to soften meat. Today, bromelain is sold in powder form as a meat tenderizer and is usually combined with papain - an enzyme found in the papaya plant (13). In fact, bromelain is such a powerful meat tenderizer that chefs claim it can turn meat into mush if marinated for too long (14).
Scientific studies on the potential benefits and uses of bromelain
Bromelain has been the focus of numerous animal studies. These were usually aimed at investigating the mechanisms and effects of this supplement on different systems of the body. Most of these studies have focused on its role in wound healing and immune function, as well as its anti-inflammatory effects.
In a study conducted at the Manipal College of Dental Sciences, it was observed that bromelain, papain, miswak and neem helped prevent plaque and gingivitis in patients undergoing orthodontic treatment. The results of this study suggest that bromelain, along with the other natural compounds mentioned, could be used as a dental cleanser to reduce the risk of poor dental health in people who wear braces (15).
Research also suggests that bromelain could have positive effects on cancer treatment by slowing or halting the growth of metastases. In a 2013 study, it was observed that bromelain had a direct effect on the growth and spread of gastric and colon cancer cells.
The primary mechanism of action involved the promotion of apoptosis among cancer cells and the activation of certain pathways for cancer cell death (16). Cancer patients also showed improved appetite and a reduction in fatigue and other problems associated with cancer treatment (17).
Bromelain has also been studied for its ability to inhibit lipogenesis, which is important for preventing obesity. A 2012 study conducted at the Institute of Microbial Technology showed that strain bromelain had the ability to reduce a buildup of fat by suppressing adipogenesis and promoting apoptosis in mature adipocytes (18).
How should bromelain be dosed?
The recommended dosage of bromelain depends primarily on the purpose for which it is to be used. Some doctors recommend taking two to three single doses per day. The standard dosage for digestive complaints is between 200 and 2,000 mg after a meal. For other purposes, bromelain can be taken in doses of 200 to 800 mg per day (19).
This dosage varies depending on the bromelain activity of the specific supplement, which is usually measured in MCU or "milk clogging units". For people who take bromelain two or three times a day, the dosage may be reduced over time depending on need (20).
Although bromelain is considered safe and harmless by numerous health organizations, it doesn't hurt to consult a doctor before taking it to make sure you're using the dosage your body needs.
Possible side effects and interactions of bromelain
Bromelain is relatively safe and does not usually cause serious side effects even when taken in large quantities. However, some people may experience allergic reactions after taking bromelain, particularly those who are allergic to pineapples. Some common symptoms of pineapple allergy include (21):
- Difficulty breathing
- congestion
- Congestion of the sinuses
- Anaphylactic shock
People who are allergic to latex, wheat, celery, carrots and fennel should also avoid bromelain supplements unless they have consulted their doctor. It should also be mentioned that pregnant women should not take bromelain, as there are not enough studies on the safety and harmlessness of this supplement for the mother and her unborn child.
Interactions with medications:
Bromelain may have drug interactions due to its effects on digestion and nutrient absorption. People taking any of the following medications should not use bromelain or limit its use:
Antibiotics: Studies suggest that taking bromelain in combination with antibiotics could increase the absorption and drug levels of these medications in the body (22).
Anticoagulants (warfarin, aspirin and non-steroidal anti-inflammatory drugs): Taking bromelain in combination with anticoagulant medications may increase the risk of excessive bleeding (23).
Sedatives: Some studies suggest that bromelain can cause drowsiness in some cases, which can dramatically increase the effects of sedatives and antidepressants (24).
People taking any of these medications should discuss the use of bromelain with their doctor in advance to ensure that they are not harming themselves rather than their health.
Bromelain is an effective, natural anti-inflammatory
Pharmaceutical companies offer a wide range of anti-inflammatory drugs, which can have negative health effects as well as their desired effects.
Bromelain supplements could provide a safe and natural alternative to synthetic painkillers and anti-inflammatory drugs. These supplements not only help to relieve inflammation, but can also help to improve the function of the immune system and reduce the risk of cardiovascular disease.
