Paleo Advocates Get Vegan Diets (and Saturated Fat) Wrong

  Quite a few people have asked me to comment on the blog Authority Nutrition. It’s written by Kris Gunnars, a medical student at the University of Iceland. First, despite the bold title of his blog, Gunnars is no authority on nutrition. His background is the usual one of the self-proclaimed expert: “I got interested […]

Staying Strong on a Vegan Diet: Protein and Muscles

We all know that it’s easy to meet the protein RDA on a vegan diet. But what constitutes “enough protein” remains a topic of some debate among experts. Among its other functions, protein protects bone health which may in part be due to its effects on muscle mass. Unfortunately, a decline in muscle mass over […]

The New York Times, Nina Planck, and Safety of Vegan Diets

Last week brought more shoddy coverage of vegan diets from The New York Times. This time, it was a debate about the safety of veganism.

Oral Contraceptives and Vitamin B12: Is There An Issue for Vegans?

Several readers asked me about an article that appeared on the Vegan Mainstream website linking oral contraceptive use to vitamin B12 deficiency. The writer, who was depending in part on greens and sea veggies for vitamin B12 (somebody bring me my smelling salts, please) ended up with a B12 deficiency. Unable to reverse the deficiency […]

Recommended Supplements for Vegans

Just days before everyone was talking about the Voracious [ex-] Vegan story, I received a severe scolding from a reader for my stance on supplements (this was in response to my post on omega-3s). She was adamant about the fact that “whole plant foods” can easily provide everything we need. An effort to prove that […]

Do Ex-Vegans’ Stories Make the Case Against Vegan Diets?

When I read the recent blog post by Tasha, who used to be The Voracious Vegan, it felt like déjà vu all over again. Just a couple of months ago I was blogging about another woman—Lierre Keith—whose vegan diet made her so sick that she had to go back to eating meat and, in the […]

Vitamin B12 Supplements: How Much is Enough?

In a new study from the United Kingdom, researchers found that more than half of vegan men were deficient in vitamin B12 based on their serum levels.
