An anti-vegan op-ed piece in the New York Times has received some fairly righteous debunking in an article by the Times' Public Editor.
Rachelle Leesen, a clinical nutritionist at the Children's Hospital of Philadelphia, told me that Planck's article "was extremely inflammatory and full of misinformation." She and her colleague Brenda Waber pointed me to a 2003 paper by the American Dietetic Association, the nation's largest organization for food and nutrition professionals. After reviewing the current science, the A.D.A., together with the Dietitians of Canada, declared, "Well-planned vegan and other types of vegetarian diets are appropriate for all stages of the life cycle, including during pregnancy, lactation, infancy, childhood and adolescence."
