It is hard to have absolutes when this type of thread comes up, but I think you can use history, some common sense and some science. History shows that no human population has ever been shown or documented to just eat Vegan, with the closest to this be Vegetarians; on the other hand the overwhelming history to this day shows societies eating any combination of meat, fish, dairy and vegetables, seasonal fruit and honey (obviously in more modern times processed sweet stuff has come in). I would like to see evidence to the contrary.
I believe everyone should find their health by testing what works without being dogmatic. But, this will not be popular, but it is my true self researched belief - at least 80% of humans can safely digest meat and fish, some struggle with (modern) dairy, I would say 80% of persons cannot maintain healthy biomarkers and or "feeling" of physical well being on a Vegan diet between 5 and 10 years. I say this based on the endless anecdotes on YouTube, especially by some of the most prominent movers and shakers in the movement (from a performance perspective) who have either now gone Keto or Carnivore - some names Tim Sheiff, Drew Morg, Bobby Risto. The performance angle is a confounder, but I have noted that when Vegan athletes / body builders "come out" as Vegan, they are usually already performative on an omnivorous diet and I believe carry this performance for a while (up to several years) on the Vegan protocols, I note that there then is a quiet period where the promotion abates (i.e. times / gains are no longer reported) . A bit of simple research on say the top male and female "Vegan" tennis players show meat use (

https://www.tennisworldusa.org/tenn...-djokovic-doesn-t-eat-meat-he-is-vegetarian-/). And in the non sports world no matter what view is taken, it is a disgrace to influence 1000's, telling them to eat in a certain way, only to be found to lie (Rawvana).
All to often this is the type of story I have read:

When persons say the cannot do / stick to LCHF and similar, I tend to see this is (80 / 20 rule) down to the lure of old habit carby things, not usually down to a deficiency or related medical issue - this is my truthful research experience.
I believe Veganism has been given a free pass in the press, in exactly the same manner as high carb low fat; I think the impact on soil, carb / sugar load, bio availability of the nutrients as a minimum should be looked at. The case in Belgium where a couple have been jailed due to neglect via their dietary choices for their child and this Swedish case should good food for thought

How many Type 2's (and I would widen this to the general population (especially past 40 plus) could cope with the Vegan meal examples below, I am not exaggerating when I say the carb / sugar numbers would most likely terminate me within a month - how long would you last? Would you be able to cope with the alternate option?
