All this week, the Brian Lehrer Show will be taking a closer look at some of the most pervasive nutrition myths with Sophie Egan, author of How to Be a Conscious Eater: Making Food Choices That Are Good for You, Others, and the Planet (Workman, 2020), and contributor to The New York Times, most recently the article "myths.html">10 Nutrition Myths Experts Wish Would Die". Today, she and Daphene Altema-Johnson, program officer with the Food Communities & Public Health Program at the Johns Hopkins Center for a Livable Future, will dispel the myth that white potatoes are unhealthy and the notion that plant-based milks are better for you than cow's milk.
