>> I simply take it to be the case that veganism is the flat-earth-theory of 2019.

> And you wonder why nobody takes your comments seriously.

My cheeky comment, in regards to veganism being the flat-earth-theory of 2019, was in response to your ludicrous suggestion to me that I should blindly accept something silly just because "so many people [...] consider veganism [...] actually positive". And it is nothing to do with my next response (to your follow-up comment of equally no substance re: good faith) that good faith on my, and others, part have already come by and been downvoted into oblivion (furthermore you are totally unaware of this happening).

> The American Dietetics Association, the largest association of professional dieticians in the world, says vegan diets are healthy and appropriate for all ages:

So what? Is the American Dietetics Association your religion, and whatever they espouse is to be taken as gospel?

Just because something is posted on pubmed does not make it a fact.

> Science is on our side.

Hah, nope. Science is _not_ on your side. And posting links to pubmed does not automatically make you scientifically-minded. The American Dietetics Association, and the like, that you so fondly identify with are wont to rely on epidemiological studies (which are not exactly science).

The vast majority of human nutrition research — including the lion share of the research cited in the EAT-Lancet report — is conducted using the tragically flawed methodology of nutrition epidemiology. Nutrition epidemiology studies are not scientific experiments; they are wildly inaccurate, questionnaire-based guesses (hypotheses) about the possible connections between foods and diseases. This approach has been widely criticized as scientifically invalid [see here <https://www.frontiersin.org/articles/10.3389/fnut.2018.00105... and here <https://jamanetwork.com/journals/jama/fullarticle/2698337>], yet continues to be used by influential researchers at prestigious institutions, most notably Dr. Walter Willett. An epidemiologist himself, he wrote an authoritative textbook on the subject and has conducted countless such studies, including a recent, widely-publicized paper tying low-carbohydrate diets to early death. In my reaction to that study <https://www.psychologytoday.com/ca/blog/diagnosis-diet/20180..., I explain in plain English why epidemiological techniques are so untrustworthy and include a sample from an actual food questionnaire for your amusement.

Even if you think epidemiological methods are sound, at best they can only generate hypotheses that then need to be tested in clinical trials. Instead, these hypotheses are often prematurely trumpeted to the public as implicit fact in the form of media headlines, dietary guidelines, and well-placed commission reports like this one. Tragically, more than 80% <https://rss.onlinelibrary.wiley.com/doi/full/10.1111/j.1740-... of these guesses are later proved wrong in clinical trials. With a failure rate this high, nutrition epidemiologists would be better off flipping a coin to decide which foods cause human disease. The Commission relies heavily on this methodology, which helps to explain why its recommendations often fly in the face of biological reality.

> Who's the flat earther here?

Given that science was never on "your side" in the first place, all you need to do in order to answer this question is to look in the mirror.
