I really wish he did his research without being restricted to a vegan diet. He mentioned in one of his videos that his choice for a vegan diet isn't motivated by health, so I can't help but think that part of these recommendations are just there to mitigate the effects of that specific diet. For example, an omnivorous diet might not need certain supplements.

I am glad he is focusing on a vegan diet (especially if no technological revolutions are made in artificially derived animal products). It's nice to learn about the downsides of it in order deal with them rather than just defaulting back to animal products.

One of his main points in the intro is not destroying our biosphere and going vegan is the single most impactful thing an individual can do to support that. Supplementing B12 is not that hard of a task to ask from a population which already swallows pills and powders by the kilograms a year.

> not destroying our biosphere

Not sure that having people live longer helps with that.

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.

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.

>b12 (because livestock are supplemented with it)

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

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,?
