A new report from the World Cancer Research Fund (WCRF) links obesity to 12 types of cancer. The report, Diet, Nutrition, Physical Activity and Cancer: a Global Perspective, analyzed a decade of research to develop cancer prevention recommendations. The analysis found strong evidence that being overweight or obese throughout adulthood increases risk of cancer of the mouth, esophagus, stomach, pancreas, gallbladder, liver, colon, breast (post menopause), ovaries, endometrium, prostate (advanced), and kidney.
The prevalence of obesity is increasing worldwide. To reduce cancer risk, the WCRF recommends being physically active; limiting fast foods; eating a diet rich in whole grains, vegetables, fruit and beans; and limiting consumption of red and processed meats, sugar, and alcohol. They also advise getting nutrients through diet, not supplements, and encourage breastfeeding when possible.
