The University of Texas MD Anderson Cancer Center, the American Institute for Cancer Research and WebMD provide lists of recommended nutritional foods for cancer patients on their respective websites. All three sources emphasize the nutritional importance of fruits, vegetables, whole grains and beans.
Extreme diets may not include nutrients that are essential for cancer patients undergoing therapy, according to WebMD. Meals that include half a plate with fruits and vegetables are ideal for cancer patients. It is important to avoid sugary foods and processed meat, and cancer patients should opt for fish and lean meat over red meat, as well as eating meat-free dishes a few times a week. The list provided by the University of Texas MD Anderson Cancer Center is organized by food category, while the American Institute for Cancer Research's list provides information on foods that individuals often inquire about.
