Carol Ann Rinzler is the author of more than twenty books on health and medicine, including Nutrition For Dummies, an international bestseller translated into fourteen languages. Rinzler's award-winning Estrogen and Breast Cancer: A Warning for Women was among the first to document the link between hormone therapy and an increased risk of breast tumors. Her four books in the Dummies series (Nutrition plus Controlling Cholesterol, Weight Loss Kit, and Heartburn & Reflux) make complex medical facts and figures accessible to the general reader.
