Nutrition and cancer?


This week the new report from the World Cancer Research Fund on the association between nutrition, physical activity and cancer will be published (see http://www.wcrf.org/). This report is the result of one of the most comprehensive series of systematic reviews and meta analyses. The title of the new report is Food, Nutrition, Physical Activity and the Prevention of Cancer.

In a process that has taken five years, an expert panel of 21 renowned scientists from around the world reviewed and assessed the body of research on the relationship between food, nutrition (including obesity) physical activity and cancer risk. The expert panel has drawn conclusions based on this evidence and developed 10 health recommendations for the prevention of cancer.

Based on early ecological studies and case-control studies it was hypothesized that nutritional factors such as fat intake, fiber intake and fruit and vegetable consumption were strong determinants of risk for certain cancers.
In the last decades more and more longitudinal cohort studies have become available, and these studies show that the association between diet and cancer risk appears to be much weaker than was believed from the earlier weaker designed investigations.

However, the WCRF reviews will probably also make clear that obesity is a major risk factor for certain cancers, such as breast cancer.
