Do you think there are any health benefits of turning into vegan or vegetarian?

Not much but balance is good. Humans were and still are meat eaters and designed to be. Until we no longer have incisors then it might mean we should change. Just look at the difference in animals that eat primarily meat versus those that eat nothing but greens and you will see the vegans have crushing teeth only except the very from that are made for cutting off shoots. Primarily meat eaters have that and incisors like the fangs on dogs.

So go tell you snowflake tree hugging friends to go f themselves as it is not healthy.
