A recent report by the World Cancer Research Fund titled FOOD, NUTRITION, PHYSICAL ACTIVITY AND ENDOMETRIAL CANCER 2013 provides additional support for a Paleo approach to nutrition and fitness:
The evidence that greater body fatness (reflected by BMI, measures of abdominal girth and adult weight gain) is a cause of endometrial cancer is convincing. Glycaemic load is probably a cause of endometrial cancer, and physical activity and coffee both probably protect against this cancer.
Evidence for non-starchy vegetables and red meat was no longer suggestive of an association and was too limited to draw a conclusion.
