I know people who really thrive on a vegan diet. And I do understand the ethical thoughts behind it. I've tried it a couple of years before I got sick, for health and ethical reasons - it was macrobiotic-ish and I really did enjoy that food. But in the end it just didn't work out for me healthwise.For the record, I do advocate for a vegan diet, for the societal and environmental benefits, but it won't magically cure any health issues.
