Is Meat Healthy? 8 Myths About Meat and Your Health
There is a lot of nonsense in nutrition.
One of the worst examples is the constant propaganda against meat consumption.
Here are 8 ridiculous myths about meat consumption and health.
1. Meat Rots in Your Colon
Some people claim that meat doesn’t get digested properly and “rots” in your colon.
This is absolute nonsense, probably invented by dishonest vegans in order to scare people away from eating meat.
What happens when we eat meat, is that it gets broken down by stomach acid and digestive enzymes.
In the small intestine, the proteins are broken down into amino acids and the fats are broken down into fatty acids.
After that, they get absorbed over the digestive wall and into the bloodstream. There’s nothing left to “rot” in your colon.
If you want to know what really “rots” in your colon, it’s indigestible plant matter (fiber)… from vegetables, fruits, grains and legumes.
The human digestive system doesn’t have the enzymes necessary to break downfiber, which is why it travels all the way to the colon.
There, it gets fermented (rots) by the friendly bacteria in the intestine, which turn it into nutrients and beneficial compounds like the short-chain fatty acid butyrate (1).
So, meat doesn’t rot in the colon. Plants do… and this is actually a good thing.
Bottom Line: The nutrients in meat are broken down and absorbed way before they reach the colon. However, fiber from plants does ferment (“rot”) in the colon, which is actually a good thing as it feeds the friendly bacteria.
2. Meat Is High in Harmful Saturated Fat and Cholesterol
One of the main arguments against meat, is that it tends to be high in both saturated fat and cholesterol.
But this really isn’t a cause for concern, because new science has shown both of them to be harmless.
Despite being seen as something to be feared, cholesterol is actually a vital molecule in the body.
It is found in every cell membrane and used to make hormones. The liver produces large amounts of it to make sure we always have enough.
But even when saturated fat and/or cholesterol cause mild increases in LDL, this is not a problem because they change the LDL particles from small, dense LDL (very bad) to Large LDL, which is protective (11, 12).
Therefore, it is not surprising to see that in population studies that include hundreds of thousands of people, saturated fat and cholesterol are not associated with an increased risk of heart disease (15, 16).
In fact, some studies show that saturated fat is linked to a reduced risk of stroke, another very common cause of death and disability (17).
When they put this to the test in actual human experiments, making people cut saturated fat and replacing it with “heart healthy” vegetable oils (which happen to lower cholesterol), it actually increases the risk of death (18).
Bottom Line: It is true that meat tends to be high in saturated fat and cholesterol, but this is not a cause for concern because they do not have adverse effects on blood cholesterol or increase the risk of heart disease.
3. Meat Causes Heart Disease and Type 2 Diabetes
Strangely enough, meat is often blamed for Western diseases like heart disease and type 2 Diabetes.
Heart disease didn’t become a problem until the early 20th century and type 2 diabetes only a few decades ago.
Blaming an old food for new health problems makes absolutely no sense.
Fortunately, we do have two very large, very thorough studies that can put our minds at ease.
In a massive study published in the year 2010, researchers pooled data from 20 studies that included a total of 1,218,380 individuals. They found no link between consumption of unprocessed red meat and heart disease or diabetes (20).
Another major study from Europe that included 448,568 individuals found no link between unprocessed red meat and these diseases (21).
However, both of these studies found a strong increase in risk for people who ateprocessed meat.
For this reason, it is very important to make a distinction between the different types of meat.
Many studies apparently showing that “red meat” is harmful didn’t adequately make the distinction between processed and unprocessed meat.
Processed foods in general are pretty awful… this isn’t just true of meat.
Bottom Line: Many massive studies have examined the relationship between meat consumption, heart disease and diabetes. They found a strong link for processed meat, but no effect for unprocessed red meat.
4. Red Meat Causes Cancer
One common belief is that meat, especially red meat, causes cancer.
This is where things get a bit more complicated.
It is true that processed meat is associated with an increased risk of cancer, especially colon cancer (22).
But when it comes to unprocessed red meat, things aren’t as clear.
Although several studies suggest that even unprocessed red meat can raise the risk of cancer, review studies that pool the data from many studies at a time show a different picture.
However… it does appear that the way meat is cooked can have a major effect on its health effects.
There are several ways to prevent this from happening… such as choosing gentler cooking methods and always cutting away burned or charred pieces.
So the answer is not to avoid red meat, but to make sure not to burn it.
Keep in mind that overheating can cause harmful compounds to form in many other foods. This is NOT exclusive to meat (26).
Bottom Line: The link between unprocessed red meat and cancer is very weak in men and nonexistent in women. This may depend on the way meat is cooked, because overheating can form carcinogens.
5. Humans Are Naturally Herbivores and Not “Designed” For Meat Consumption
Some vegans claim that humans aren’t “designed” to eat meat.
They say that humans are naturally herbivores like our primate ancestors.
Our digestive systems really don’t resemble those of herbivores at all.
We have short colons, long small intestines and lots of hydrochloric acid in the stomach to help break down animal protein (29).
The length of different parts of our digestive system is somewhere in between the lengths typical for both carnivores and herbivores, indicating that humans are “designed” to be omnivores (30).
It is also believed that our consumption of animal foods helped drive the evolution of our large brains, which set us apart from any other animal on earth (31).
Humans function best eating both animals and plants. Period.
Bottom Line: Humans are well equipped to make full use of the nutrients found in meat. Our digestive system reflects a genetic adaptation to an omnivorous diet, with animal foods as a major source of calories.
6. Meat is Bad For Your Bones
Many people seem to believe that protein is bad for the bones and can lead to osteoporosis.
The theory goes like this… we eat protein, which increases the acid load of the body, then the body moves calcium from the bones and into the bloodstream to neutralize the acid.
There are in fact some short-term studies to support this. Increasing protein does lead to increased calcium loss from the body (32).
However, this short term effect does not appear to persist because the long-term studies show that protein actually has beneficial effects on bone health (33).
This is a great example of where blindly following the conventional wisdom in nutrition will lead to the exact opposite result.
Bottom Line: Despite protein causing increased calcium loss in the short term, the long-term studies show that a high protein intake is linked to improved bone density and a lower risk of osteoporosis and fractures.
7. Meat is Unnecessary
It is often claimed that meat is unnecessary for health.
This is actually kind of true… most of the nutrients in it can be found in other animal foods.
But just because we can survive without it, it doesn’t mean that we should… quality meat has many nutrients that are good for us.
This includes quality protein, vitamin B12, creatine, carnosine and various important fat-soluble vitamins, which vegans and vegetarians are often lacking in.
Whole foods like meat contain way more than just the standard vitamins and minerals that we’re all familiar with it. There are literally thousands of trace nutrients in there… some of which science has yet to identify.
The fact is, humans evolved eating meat and evolution designed our bodies with these nutrients in mind. They are an essential part of the immensely complex biological puzzle.
Can we live without meat? Sure… but we won’t reach optimal health, making use of all the beneficial nutrients that nature has provided us with.
Although we can survive without meat, the same could be said of most other food groups… including vegetables, fruits, legumes, fish, eggs, etc. We just eat more of something else instead.
Quality meat is pretty close to being the perfect food for humans. It contains most of the nutrients we need.
There is even a study in the literature where two guys ate nothing but meat and organs for a year and remained in excellent health (37).
Of course, not all meat is the same. The best meat comes from animals raised on pasture, fed the types of foods they would eat in nature.
Bottom Line: Some claim that meat is unnecessary. Although it is true that we can survive without it, there are still many nutrients in there that are important for optimal health.
8. Meat Makes You Fat
Meat is often believed to be fattening.
This seems to make sense on the surface because most meat is pretty high in fat andcalories.
However, meat also happens to be one of the best sources of highly bioavailable protein. Protein is the most weight loss friendly macronutrient, by far.
There are also studies showing that if you increase your protein intake, you automatically start eating less of other foods instead (42).
Eating more protein also tends to favour increased muscle mass. Muscle is metabolically active and burns a small amount of calories around the clock (44).
If anything, the more you eat of high quality meat (and less of other foods instead), the easier it should be for you to lose weight.
