An Interview with Ward Nicholson now has three parts on the web. Good overview of man's diet over the past 65 million years. Long but highly recommended reading. First published in Chet Day's "Health & Beyond" newsletter. Now part of a very comprehensive Beyond Vegetarianism site. Every argument that your vegetarian friends use to avoid meat for health reasons is debunked here.

Dr. Georgia Ede reviews the EAT-Lancet’s global nutrition study, “Food in the Anthropocene—the EAT-Lancet Commission on healthy diets from sustainable food systems,” which envisions a “Great Food Transformation” based on minimizing consumption of animal foods. She concludes, “the report fails to provide us with the clarity, transparency and responsible representation of the facts we need to place our trust in its authors. Instead, the Commission’s arguments are vague, inconsistent, unscientific, and downplay the serious risks to life and health posed by vegan diets.”
