Why so? A vegan diet when supplemented is an easy way to avoid potential bad consequences of animal products, such as heart disease, cancer, obesity or diabetes.

The only real thing that meat-eaters do not have to supplement that vegans do is b12 (because livestock are supplemented with it) and maybe omega 3.

40% of the population is B12 deficient: https://eatingourfuture.wordpress.com/science-studies-vegan-...

So most people should supplement, not just vegans.

This directly contradicts the Wikipedia article on the subject [1], and in general the page you link looks more like pseudoscience than not. Do you have a better source, maybe from a published paper or the NIH?

If the vegan diet was one of the outcomes from his experiments (where the goal is to optimize for anti-aging), I'd be fine with it. But it's a restriction he put on himself based on a ethical/philosophical motivation.

Why would he have to experiment with it? He didn’t have to experiment with exercise before starting an exercise plan.

>b12 (because livestock are supplemented with it)

What do you mean "supplemented"? The vitamin comes from animal sources.

[bmikaili]

Livestock is given B12 supplements. B12 only occurs naturally in soil, where the concentrations are too low for even animals to bind. Prehistoric humans probably ate more dirt and had enough of it.

And maybe omega-3? That’s underplaying the role of long chain PUFAs by a lot.

And when you say annual products, are you talking about all animal products, like seafood? Because there is a vast difference between oysters, muscles, and salmon, and industrial farm raised beef.

And animal products, again, are you excluding the organ meats, which are extremely high in many things that could possibly extend our lifespan? Like riboflavin, manganese, zinc,?
