These are the foods a doctor buys - and avoids - at the grocery store
Michael Ruhlman, a chef and author, does just that in his book "Grocery: The Buying and Selling of Food in America."
Roxane B. Sukol, a preventive medicine specialist and the medical director of the Cleveland Clinic's Wellness Enterprise, takes Ruhlman through the aisles of her local grocery store to point out which foods she picks, which products she avoids, and which sections she spends the most time in at the market.
