We are fortunate to live in one of the most well-informed societies ever, yet the majority of us have no idea how to analyze and understand the cornerstone of information in our modern age: science. It seems that there is a scientific study to prove anything, and a corresponding sucker who will believe it.

I know a young man who is adamant that all grains (refined or whole) are destructive to your health and insists you must have meat in your diet. His arguments are cogent, and he is knowledgeable on the subject citing a variety of authors and scientific studies. How can we argue with that? We can and we must because the vegan community actually has the weight of scientific truth on our side.

Decoding Scientific Studies

If one study, or even ten studies imply that something is so, does that make it a scientific fact? Our society is in need of a set of comprehensive skills that allow us to rigorously analyze scientific data and make informed judgments about the validity of the information. We need to ask critical questions such as: was this a peer reviewed, double blind/controlled study? Is it published in a reputable scientific journal? How many test subjects were there? Ten? One hundred? Tens of thousands (like the Harvard Nurses study, or the China Study for example). What is the duration of the study conducted? Even if all these factors are satisfactory, how many times was this study conducted with the same results? And perhaps most importantly, have the findings been accepted by major health organizations charged with the responsibility of analyzing all available data and presenting the public with a position?

It is important to consider who sponsored or funded the study as well. You can find lots of studies saying milk does a body good, but who paid for those studies? If you investigate deeply you will find that the dairy industry is behind much of this “research.” Likewise there are a plethora of studies showing that evolution is impossible, and global warming is a myth. But why do most reasonable people accept evolution and global warming as scientific truths? Because the majority of the scientific community has come to the certain conclusion that they are truths based on the rigorous analysis of the facts. We must have a consistent standard that we apply to all science, regardless of our political or pious prejudice.

Who Can You Trust?

For an analysis of nutrition, reputable organizations such as the American Dietetic Association, American Cancer Society, American Heart Association, can be good sources.  These organizations take hundreds, even thousands, of peer-reviewed studies, compiled over decades, and come to collective conclusions based on these studies.  Not surprisingly, they have all come to pretty much the same conclusion on nutritional recommendations. Unfortunately they lack the marketing power that food and supplement industries enjoy.

Simply put, every mainstream health organization recommends eating more vegetables, fruits, and whole grains and imposes restrictions on meat consumption. What is the natural extension of this recomendation? A plant-based diet. These organizations will mention meat and dairy but encourage it’s intake in much smaller amounts, sometimes twice a week, as opposed to every meal. They are mainstream agencies and are cautious not to scare people away, but the message is clear- eat more veggies and fruits, less meat and dairy. They know that this will reduce the harmful, risk-factors that animal products establish in the diet. The American Dietetic Association even recommends more veggies and restricted or no meat for athletes.

There is a reason mainstream health organizations are trying to get the public to eat more fruits, veggies and whole grains. Plant-foods are high in fiber, phytochemicals and antioxidants, have no cholesterol and are generally low in saturated fat (with the exception of coconuts, palm kernel oil, and an insignificant amount in nuts and seeds). Conversely, animal products are high in both cholesterol and saturated fat, and are completely devoid of cancer-fighting fiber and phytochemicals.

The Tide is Turning

A hopeful sign that mainstream nutrition is moving in the veggie direction is the new food guide, MyPlate recently unveiled by the U.S. Department of Agriculture and the U.S. Surgeon General. MyPlate replaces the Food Pyramid, the standard nutrition guide since 1992.

The innovative new guide shows four portions on an image of a plate with vegetables and grains being the largest segments, with fruit and “protein” making up the smaller sections. Not only is it very exciting that the vegetable and grain section are by far the largest slice of the plate, but it is also noteworthy that vegetables, fruits, and grains are listed as “food”, while the fourth section, “protein” is listed simply as a nutrient. Not as “meat”, or as “meat/beans” but just as protein. The other sections could be listed as “carbohydrates” or “vitamins” but they are not. It is apparent that they are specifically recommending eating vegetables, grains, and fruits, however, how you get your protein is optional. The clear message is that meat is no longer recommended or required in the diet. This is truly a turning point in mainstream nutrition education. This is practically a vegan plate!

So, contrary to the beliefs of my aforementioned friend, actually, whole grains are a perfect staple food, meeting the nutritional recommendations of every major health organization in the U.S. Despite our small (but growing) numbers, there is nothing “fringe” or “radical” about veganism in terms of scientific validation; it is simply an extension of mainstream health recommendations to eat more plants and restrict animal foods. Anyone can cite a study to the contrary, much like the anti-climate change camp, or the anti-evolution crusaders. But the position of mainstream health organizations takes into consideration the entire body of literature available, and make recommendations based on the weight of that scientific research, not simply citing the self-serving bias of some rogue studies. And their recommendations are increasingly supportive of plant-based nutrition.

So the next time someone is spouting facts and studies supporting a claim, check the science. Don’t just believe someone because they have letters after their name, or they are telling a story that sounds believable. Be critical thinkers. Research and look into it. Scientific truth is a powerful tool if we choose to utilize it.

Showing a study or two and claiming it to be factual, is not real science. lol This is one reason why people laugh at and make fun of Vegans and Vegetarians, they use no logic or reasoning what so ever in their argument. Want to know what a fact is? The Heart is Beating. That\'s a scientifc fact. A study is not a scientific fact. It\'s a bunch of random variables and hoopla B.S. without actually doing any real science.

So, to argue that the Vegan and Vegetarian diet is backed by science, is utterly stupid and flawed. The only solid argument that Vegans have is choice. That\'s it. For every other argument that they have, it can be rebuked by real knowledge and understanding of the world around us. This is called reality. Vegans do not live longer than meat eaters. Period. You have no scientific evidence of this. Oh and I likely will not be back to this site because of the fricken ads popping up all the time. It\'s utter nonsense too.

So, unless you have real, legitimate science to back up your claims, you should stop touting studies as actual science. It\'s nothing more than a bunch of pseudo science B.S. This is why the Vegan community is losing a large amount of people. Not because they\'re doing it wrong, because there is no actual factual science to back it up.

I call Shenanigans on your Shenanigans. The only real reason why people are Vegan, is to belong to an excluse group of people. It\'s elitist Bull Shit at its finest. So yeah, you keep your filthy, unhealthy diet, I\'ll keep my Bacon and triple cheese burgers. :)

If you want to peruse the huge bulk of scientific evidence favouring the whole food plant-based diet over vegetarian and omni diets, why not visit Dr Gregor\'s website http://nutritionfacts.org; it provides free short videos on health-related topics, all revolving around a non-processed plant-based diet.

Great article, thoroughly enjoying researching veganism and educating myself on the topic out of curiosity on various fronts. I feel that I should forward findings on several of the advisory bodies that you mention. The American Dietetic Association, American Cancer Society, American Heart Association, are all discussed in The Protein Myth by David Gerow Irving who contests their legitimacy due to funding sources and business ties. From what I read in the book, I would doubt their accuracy and ability to fully advise the public due such constraints. Their messages, he suggests, tend to be a watered down version of the truth, formulated to placate those in control (the funding organisations)

I would have to completely agree. I would never trust any of the sources coming from the American Dietetic Association, American Cancer Society or American Heart Association. Especially the Cancer Society. Where do you think they get their funding? And to say that they have a lack of funding is crazy. The multi-national co-operations cash in on the vegan life style probably more than any other diet, with the likes of Monsanto. You\'re caught in almost every direction.
On being vegan, or any other extremest diet, I\'d say if it works for you.. run with it. If not, change it up until you find something that does. I find this article to be quite smug and sneery if I\'m being honest!

As a recovering vegan, first of all, I get where you're coming from. I was a vegetarian for over 30 years. And not just any vegetarian. Whole foods. Whole grains. Real food. Healthy food. Statistics, studies, and numbers are good and necessary, but in the end the only real "study" that matters is a study of one. That is to say, what does a vegan diet do for your health personally? In the end, my "healthy" vegan diet was destructive to my health and I was forced to abandon it at the beginning of this year. All things being equal, I prefer my vegan diet. But all things are not equal, and I needed to find out and eat what was healthy for me. What is healthy for me includes a serving of meat, fish, or eggs at least twice a day. Lots of non-starchy vegetables, some fruits and nuts. And no grains, whole or otherwise, because grains are destructive to my health. I'm not going to go so far as to say they are destructive to everyone's health, but it's something to consider in certain cases.

Glad to see someone finally bring up that legitimate studies do reflect that Mother Nature knows best, she did not equip humans to be meat eaters. As human beings we should respect her, ourselves and our animal friends. As vegans we claim to not harm animals and we should never harm our fellow creatures, no matter what they eat. Recently it has come to my attention that out of our sincere hope to save homeless pets, dogs particularly, we may have missed something. We may be doing unintended harm to our dogs by S/N. According to numerous peer reviewed medical studies S/N can cause (and has caused, per retrospective studies) some pretty serious health problems for our furry friends, more than it could alleviate, as we have been taught to believe. We do not want pet overpopulation but do we want to deprive our dogs of critical health supporting endocrine hormones? Apparently there are many serious diseases that happen due to hormone loss after we remove our friends gonads. I am wondering wether or not the vegan community has applied any "critical thinking" to this important issue? One woman at least has seriously looked into this and covered a lot of ground in her review of medical studies: http://www.naiaonline.org/pdfs/longtermhealtheffectsofspayneuterindogs.pdf, not all of it, and there are many additional studies out there now being noticed but it seems like all of us animal lovers have been ignoring these scientific findings or just never heard about them. I am wondering what the author of this excellent vegan article thinks of this?

I disagree with the first statement made here but I agree with helping our dog friends. Mother nature did not make us, God did, or whoever you believe in. We, by physical means WERE made to eat meat and plants. We are born OMNIVORES. Not herbivores. Us humans have been meat eaters since the dawn of time so that\'s why we have certain structures. We chew food by chomping up and down, left to right. Up and down is the equivalent to that of meat eaters and side to side is that of plant eaters. Conclusion is, we are omnivores made to eat BOTH meat and plants. If everyone on earth ate the proper equivalent of meat, veggies, fruits, etc. in proportion, we wouldn\'t ever have a problem with "killing off the animals". Many Vegans claim Mother Nature has a huge role in this and if she does, she is damn well capable of keeping the animals alive herself if that\'s the fate of it. Many animals we eat today weren\'t ever meant for free roaming. Chickens would get gigantic and overpopulate, imagine turkeys at 4 times their current size! Cows were breed for consumption (milk, cheese, meat) and a study came out (backed by a real test) that there are no harmful hormones in meat. It would be rediculous to believe so though considering animals aren\'t made out of different "material", if you will, than us. Now, I\'m not telling you or anyone else to not be vegan but I find the majority of "info" to be a load of bs based off of how society has lived years in the past. I tried to go vegan, it was hard to get past the cravings so I dropped it. If going vegan works for you and you feel satisfied, go for it. I\'m just tired of vegans forcing their bs onto those who have no intentions of turning. Don\'t get me wrong, plants are great but meat has a lot of benefits to your physical health as well.
