Just to clarify, it’s dramatically better for the environment, not necessarily for the individual’s health. Although a vegan diet can be healthy for the individual, too. You just have to know what you’re doing.
A vegan diet is far, far healthier than the average American diet even if the vegan doesn’t have a clue about nutrients and just eats a balanced diet with good healthy food. The only way you end up with significant B12 deficiency or other vitamin/mineral deficiencies is if you eat an even more restricted diet (for example, raw vegan), and even then a B12 supplement is much healthier than red meat.
Eating 2/3 of your meals made entirely of pureed dog shit is probably healthier than the average American diet. So, not exactly a ringing endorsement.
What I meant by that is some people don’t know how to eat a balanced diet. If someone suddenly decides they are vegan and doesn’t learn how to eat correctly (e.g. they start eating nothing but noodles and bananas), they could run into trouble.
