This has stirred up quite a controversy.
She posted here, ten days ago, about the medical and spiritual journey that led her back to eating meat, after years as a vegan. (Her story is similar to the story told by Lierre Keith in the excellent book, The Vegetarian Myth.)
Tasha received so many views and comments on her blog that her web server crashed. She also received death threats and other harassment from putative vegans and animal rights activists. She posted here, a few days later, about this fallout.
Many of the constructive comments on the blog post are worth reading. And lots of other folks have blogged insightfully about the situation; you can find trackback links at the bottom of Tasha's posts.
Some of the perspectives represented in the comments include vegans who are having similar health problems; vegans who are doing just fine; pseudo-vegans who secretly eat meat; omnivores who eat only Meat Of Known Origin; and a good number of people who are concerned most of all for Tasha's well-being, and are happy to hear that her health has improved dramatically.
My observation:
Many vegans are motivated by concern for animal welfare. They are horrified by factory animal farming.
Many thoughtful omnivores are also motivated by concern for animal welfare, and are also horrified by factory animal farming.
We all want to see a food system that is healthier and more just for everyone. We all have different ideas about exactly what that looks like, and how to get there. And each of us has ideas that evolve over time.
Fundamentally, our goals and motivations are similar.
I would ask us all to focus on our common ground, where possible, rather than focussing on our differences.
