Human biology, perhaps? After all, haven't we evolved over thousands of years to be omnivores?

In other words, according to you, people who aren't interested in being vegetarian lack intellectual curiosity. It's a little strange to see a comment so boastful of intellectual intolerance on HN...

It's not necessarily the lack of interest, but instead the absolute choice to not consider it at all.

In terms of biology plenty of humans thrive on vegan and vegetarian diets.

I know plenty of vegetarians and a few vegans. While vegetarians do relative okay especially if they eat eggs, the vegans are forever talking about supplements and are fatigued and look like 60 by the time they are in their 40s.

You have no idea what you are talking about. Those are anecdotes and it sounds like you're biased.

There are plenty of athletes on a vegan diet. Sure we take B12, but plenty of omnivores are deficient as well. The only reason you get more of that is because it's supplemented to livestock.

My blood tests came back absolutely stellar and I eat whatever I want most days. When it comes to sports, I can easily compete with my omnivore friends.

Just describing what I see. I don't disagree that there may be a few people who do fine with it, in general, it is a huge overhead to make sure you are getting enough as a vegan. As a omnivore you can grab that steak and go.
