Flaumig: Vegans will tell you that eating vegan is healthy.  In reality, a vegan diet cannot provide vitamin B12 (B12 from plant sources is not in a form digestable by humans) and is very much lacking in taurine, carnitine, calcium, and Vitamin D.  If you eat vegan, you have to take supplements to get those missing or insufficient nutrients.  Pretty much by definition if you have to supplement your diet from non-food sources in order to get sufficient necessary nutrients, it's not a healthy diet.

Arguing against dietary supplements is really weak considering the widespread deficiencies in non-vegan populations. "Oh you take an iron pill? Your diet isn't healthy!" Give me a break.

There is no "B12 from plant sources". There's pseudo-B12, which the name gives away as not being B12. All B12 is produced by bacteria. Food animals are given B12 injections, and a good percent of non-vegans are still lacking and should supplement.

There's no dietary requirement for taurine or carnitine. Calcium is readily available from plant sources. D needs to be supplemented for a large portion of the general population, vegan and non-vegan alike.

None of it is an argument against veganism. A vegan diet could be lacking in dozens of nutrients and require a daily horse pill and still be the right thing to do. Trying to make an argument that one diet is superior than another on the basis of fortification/supplementation when they get to the same place regardless is anti-science and a roundabout appeal to nature.

Vegans will tell you that anyone can be vegan.  In reality, some of the staples of the vegan diet, soy, wheat, peanuts, and tree nuts, are among the most common food allergies.  Tens, if not hundreds of millions of people around the world would get sick or die on a vegan diet.

Right. Because a vegan absolutely has to have soy. Or peanuts, or wheat, etc. No one is getting sick or dying because they can't have peanuts. Even an extreme fringe case of someone allergic to every plant food would say absolutely nothing about everyone else who gets on fine.

Vegans will tell you that veganism is the most environmentally sustainable diet.  In reality, it's not even close.

You actually linked to a source that didn't completely misrepresent the study and still managed to get it wrong. The study is about how to maximize food output. To do so, you can have grazing animals on land that doesn't support human food crops very well. That's it. There is no need to do so. And it's glaringly obvious that growing food crops directly instead of passing them through food animals would reduce total land requirements for food.

Vegans will tell you that veganism is cruelty free.  In reality, much of the workforce that provides food for the vegan diet is mistreated and underpaid.  People in South America are starving because most of their primary crop, Quinoa, is being exported to the US.  What little that is left behind is priced so exorbitantly that many cannot afford it.  Rainforests in Mexico are being destroyed to make space for growing avocados to keep up with the increased demand.

What, you don't eat plants? You gave two examples of foods people eat, and wrote some nonsense about quinoa. Stop repeating sensationalist bullshiat from British tabloids. Land is being cleared for avocados because, get this, people eat them. Here's an idea though, lets stop clear cutting for cattle and just farking grow avocados on a fraction of that land.

Veganism is bullshiat, and vegans are all either charlatans or gullible fools.

Add a few more bullshiat items to your list and you'd be on your way to a full on gallop. It's disappointing people have smarted your post, but maybe they'll have a second thought now, look up some credible sources, and not just believe bullshiat that conforms to their bias.

Photoshop This: That "What the Health" documentary is loaded with bs and misleading information. https://www.vox.com/science-and-health/2017/7/25/16018658/what-the-health-documentary-review-vegan-diet

It sure is.
