The formal study of diet, nutrition and cancer is still relatively young, with most epidemiological studies and randomized controlled trials (RCTs) having occurred in the last twenty to thirty years. Despite methodological challenges of studying diet and cancer in free-living populations, there is scientific consensus that overweight and obesity increase the risk of certain cancers and growing evidence that dietary patterns rich in vegetables, fruits, and whole grains and low in red and processed meat are associated with lower risk of colorectal cancer and total cancer mortality. Although it is more difficult to isolate the specific components of diet that affect risk, several key factors appear to play a role. Dietary composition appears to operate by both affecting energy intake and also independent of energy intake. Despite extensive research, evidence does not support an important impact of the macronutrient composition of diet on cancer risk.
