The benefits of veganism and vegetarianism have not been proven - there is no evidence of the benefits but there is evidence that it can be very harmful to the brain and accelerate human aging.
Wikipedia is one of the best sources of information. But Wikipedia is also a powerful weapon for promoting anything and creating myths that everyone will believe in later. And then try to convince someone otherwise.
So today, supporters of veganism (strict vegetarianism) have a huge influence on Wikipedia and post their scientifically inaccurate information there, which is then read by millions and billions of people on earth, and believe in it.
A reference to the opinions of vegan scientists, not scientific data.
Wikipedia often refers to the opinions of vegan scientists to confirm the benefits or harms of certain foods. But their opinion is their opinion. Science must be clear of opinions.
A vegan will say one thing, a meat-eater - another. But this is not a scientific approach. Wikipedia should only refer to scientific data.
And given that it refers to the opinion of exclusively vegan scientists, it promotes vegetarianism and veganism. But this is not Science — it is already a belief in something, unsupported by evidence.
Try looking at the following screenshot from the article or the Wikipedia article itself for "Vegetarian nutrition" and "Vegan nutrition":

Note the words "claim that". This is a reference to the opinion of some vegan scientists. A reference to an opinion, not to scientific facts. This is called an “appeal to authority”, and is a logical error that proves nothing.
Science is primarily all research and evidence, not opinions or books written by anyone without reference to research.
In this excerpt, vegan scientists suggest that animal fat and animal protein are the cause of heart disease and that a low-fat vegetarian or vegan diet can prevent and reverse chronic diseases.
But in these articles, there is no word that vegan nutrition has serious problems, primarily for the brain and human aging:
1.Research has also shown that 92% of vegans and 47% of lacto-Ovo vegetarians are deficient in vitamin B12, which is critical for the brain. Without vitamin B12, neurodegenerative diseases (diseases of the brain and nervous system) develop, which leads to rapid aging of the brain.
Vitamin B12 also carries out the reverse synthesis of homocestein into methionine in the body, which is important for the prevention of cancer and atherosclerosis.

Vitamin B12 deficiency also leads to anemia (if simply — oxygen starvation), impaired brain function, symptoms of mental disorders, and a decrease in brain mass:

There are also studies linking vitamin B12 deficiency to Alzheimer's disease (senile dementia), which ends in fairly rapid death of a person.

Symptoms of vitamin B12 deficiency: memory loss, depression, fatigue, and then permanent brain damage:

The only source of vitamin B12 for vegans is algae. But research shows that eating algae may not be enough:

2. A vegan diet is cholesterol-free and low in saturated fatty acids. And vegans consider it a useful acquisition. But cholesterol is used in the synthesis of testosterone. And saturated fat consumption is also correlated with increased testosterone levels, research shows.
http://jap.physiology.org/content/82/1/49.full
Not surprisingly, vegans have significantly lower testosterone levels than meat-eaters

http://ajcn.nutrition.org/content/42/1/127.abstract
http://www.ncbi.nlm.nih.gov/pubmed/1435181
Moreover, a lack of saturated fatty acids accelerates human aging.
3.Vegans are totally deficient in vitamin D. Vitamin D deficiency is associated with various diseases, including heart disease and cancer.
http://ajcn.nutrition.org/content/85/6/1586.long
http://archinte.jamanetwork.com/arti...ticleid=414285
Low levels of vitamin D in the blood are also associated with various brain disorders, including autoimmune diseases multiple sclerosis, depression, and cognitive impairment.
There are even cases when mothers who followed a vegan diet give birth to a child who is diagnosed with cerebral palsy or rickets, but it is worth starting to take vitamin D, as the child begins to develop.

4. Vegans have less muscle mass:

Thus, proponents of this diet use lie and fear-mongering trying to convince everyone else to eat the same way, but hide the truth about the harm of veganism and vegetarianism.
Banning meat
Wikipedia also says that vegetarians are less likely to suffer from cardiovascular diseases and cancer. But this is also not true. According to research, men who eat meat (boiled — not fried) have a lower risk of heart disease, and women who eat meat have a lower risk of cancer.
http://ajcn.nutrition.org/content/ea...62638.abstract
There is no evidence at all of the harm of cooked meat. There is only evidence of the harm of fried meat. But vegetable fried food is just as dangerous for the heart as fried meat. Here it is a matter of the method of preparation.
There are no serious studies proving that vegetarians are healthier than meat-eaters. There are only observational studies that exist to build hypotheses, but can't prove anything.
These studies compared vegetarians with meat-eaters without dividing into meat-eaters who eat fried or boiled meat. Also, meat eaters usually do not care about their health.
This is the fashion today because of the propaganda that who cares about health, he/she stops eating animal and fatty foods.
But there is a study that lasted 17 years, where they specifically compared both vegetarians and meat-eaters who care about their health. Vegetarians continued to be vegetarians, and meat-eaters continued to be meat-eaters. In this study, vegetarians had no health benefits and did not have a lower mortality rate.
www.ncbi.nlm.nih.gov/pubmed/8842068
Many pro-vegetarian links on Wikipedia refer to books, but not to scientific research.
In the screenshot above (from Wikipedia), you have already seen that there are several links that vegetarians cite in support of their point of view. For example, some links refer to a book written by Kathy Freston.
But this book claims, without any reference to research, that animal fat and animal protein are harmful to health.
There are also links in Wikipedia about vegetarianism to other books that were written by vegan doctors. Among them are the books of Dr. Neal Barnard, Dr. Colin Campbell, Dr. Caldwell Esselstyn, and Dr. Dean Ornish.
These are good books, but they only describe opinions without reference to qualitative research.
Falsifying facts about the benefits of veganism
1. Vegan scientists from the Wikipedia link in their books refer to a number of studies and articles published in respected peer-reviewed journals
One of these is a study conducted by Dr. Dean Ornish. However, the Ornish program did not only use a low-fat vegetarian diet. The study participants also quit smoking, started meditating, doing aerobic exercise, and much more as part of this program. This study did not answer the question of what would happen if patients did not change their diet, but simply stopped smoking, began to meditate, run, etc.
http://www.sciencedirect.com/science...14067369091656
And to understand what affected the patients (the Ornish diet or just a healthy lifestyle), a very large controlled study was conducted.
This study compared the low-fat vegan Ornish diet and three other diets (including the low-carb Atkins diet - a fat-rich diet). For reference, the Atkins diet does not limit the consumption of such products as meat, fish, lard, seafood, eggs. Raw vegetables are added to these products.
Well. After 1 year, it turned out that the high-fat, low-carb Atkins diet is much, and once again, much more effective than the vegan Ornish diet.
The Atkins diet showed a much more significant improvement in almost all health markers. This is the largest and best study on a vegetarian diet that anyone has ever done. But vegetarians will never say anything about this study because the results were disappointing for fans of vegetarianism.
http://jama.jamanetwork.com/article....ticleid=205916
The Atkins group lost more than 22 pounds (10 kg) of body weight, while the Ornish group lost just 5 pounds (2.3 kg).
Participants in the Atkins group had a much stronger decrease in blood pressure, a greater increase in good blood cholesterol (HDL), and a greater decrease in triglycerides.
It is particularly interesting that triglycerides in the blood of the group with the high-fat diet Atkins decreased by 29.3 mg/DL, while the group with the low-fat vegan diet Ornish - only 14.9 mg/DL.
Claims that animal fat and protein are the cause of heart disease are pseudoscientific and have no evidence. There are a lot of studies showing that animal fat has nothing to do with cardiovascular diseases:
http://ajcn.nutrition.org/content/ea...27725.abstract
http://www.ncbi.nlm.nih.gov/pubmed/9635993
http://www.ncbi.nlm.nih.gov/pubmed/19364995
Not to mention that humans have been eating animal food throughout evolution, and most of the chronic diseases of modern Western humans are relatively new. And blaming old foods for new health problems just doesn't make sense.
2. And here's another rigging of the facts, based on low-quality research showing health benefits and lower mortality in vegetarians and vegans - the Seventh-day Adventists
The problem with these studies is that they are so-called observational studies. Observational studies can only demonstrate correlation, not cause, and cannot be evidence.
http://care.diabetesjournals.org/con.../1225.abstract
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2671114/
Many vegetarians are healthier, probably because they take more care of their overall health: they eat more vegetables, most often don't smoke, exercise, etc.
This has nothing to do with avoiding animal products. And there is proof of this. So there is another study that involved 10,000 people.
All participants took care of their health (no smoking, exercise, etc.). and in this study, there was no difference in the health of people who were vegetarian and non-vegetarian.
www.ncbi.nlm.nih.gov/pubmed/8842068
There may be a question. If there is no difference, then maybe vegetarianism is still better. After all, it takes into account ethical considerations. But let's take a look at other studies.
So, one controlled study found that a vegan diet is more effective against type 2 diabetes than a regular diet recommended by the American Diabetes Association. And diabetes is one of the main causes of heart disease.
www.ncbi.nlm.nih.gov/pubmed/8842068
However, the effect of a low-carb (high-fat - with animal fats) diet on type 2 diabetes has also been studied. And the results were much more powerful than the vegan diet results.

AFTERWORD
The thesis (or postulate/statement) about the benefits of veganism is pseudoscientific. Veganism contributes to faster aging of a person (especially their brain), as well as poorer health than a diet high in animal fats and animal products — including meat.
The truth is that the health benefits of veganism are based largely on a few (unproven) observational studies, combined with some animal studies that are taken out of context.
