(Integrative Medicine) - A new study funded by the National Cancer Institute suggests that high amounts of animal-based nutrients may increase the risk for cancers of the stomach and esophagus (the tube connecting the throat and the stomach), while high intakes of plant-based nutrients may do just the opposite. Researchers interviewed 1095 patients with cancer of the esophagus or stomach as well as 687 individuals who were free of cancer in three health centers across the United States. Information was obtained about the patients' diet and eating habits through food-frequency questionnaires. They found that patients who consumed high amounts of fiber, beta-carotene, folate, and vitamin C (found primarily in plant-based foods) were significantly less likely to develop cancer of the esophagus or stomach than those who consumed low amounts of these nutrients. Those who took vitamin C supplements were also less likely to develop certain types of stomach cancer. In contrast, those who consumed high amounts of foods of animal origin, including dietary cholesterol, animal protein, and vitamin B12, were significantly more likely to develop these cancers than those who consumed low amounts of such nutrients. The researchers conclude that their findings have important implications for the prevention of stomach and esophageal cancer.
