What people eat may affect the outcome of their cancer treatment, and 60% of cancer patients look online for diet guidance. But they may be getting bad advice. Only 11 out of 21 major U.S. cancer centers have websites that either give nutrition advice or link to other sites that do, according to a recent study. Worse, the advice is contradictory—half of the websites recommend a low-fat, high-carbohydrate diet, while the other half recommend equal amounts of fat and carbohydrates. In addition, recommendations should be tailored to individual patients because nutritional needs vary by cancer type and stage. The researchers call for studies to develop sound guidelines for people's diets during and after cancer treatment.
