Very interesting article! Another reason, why do not eat any meat!

We probably don't need to eat meat in modern times but it is likely our ancestors would not have evolved large brains without it. Personally although I still eat meat I can't help but feel uncomfortable with it for animal welfare reasons.

Disagree. Vegans also get neurodegenerative diseases. And are prone that after a long Vegan diet. It's not healthy it's a religion that puts Animal Life above Human wellbeing and most of the data the quote is from flawed studies and manipulated skewed data. It's very hard for most people to do it right and they start to get malnourish over time which is why most go back to eating meat.
