Another link sent by Trevor. Vegan blogger finally admits that her health was suffering. Worth reading all the way through, just to see how difficult it is to give up beliefs in the face of evidence.
A Vegan No More
by Tasha on November 19, 2010
3.5 years of veganism didn’t just leave me exhausted, depressed, and very sick, it also filled my head with doubts and questions about the ethics of veganism. If I actually need to eat animals to be healthy, how can it be so wrong? It has been a complicated and eye-opening journey, and I now find myself in a much different place than I was 3 years ago, a year ago, or even several months ago. Perhaps if my health hadn’t improved so dramatically upon the reintroduction of animal flesh I wouldn’t be so sure, but it did improve remarkably, and now that I have my life and my happiness back, I will never give it up again. Ultimately, I can no longer think it is wrong to eat animals...
...When I stumbled along this quote about veganism by Megan Mackin it seemed as if it had been written for me: “It begins, eventually, to look like a very effective way to co-opt a movement: take the most passionate activist-minded, girls especially, and get their focus on a way of living that drains energies and enforces conformity in others. The Big Boys still run things, but now even more freely – with out much interference.”
