Cancer of the prostate: influence of nutritional factors - General nutritional factors

Obesity: Studies attempting to establish an epidemiological link between bo dy mass index and the risk of cancer of the prostate have been contradictor y. Energy intake: No straightforward relationship between energy intake and ca ncer of the prostate has been identified. Fat intake: According to epidemiology studies, there is a correlation betwe en high-fat diet and the incidence of cancer of the prostate. it has thus b een demonstrated that men whose diet contains more than 30 to 40% fat have a higher risk of developing cancer of the prostate than those whose diet co ntains less than 30% fat. In addition, high-fat diets favor progression of tumors in elderly subjects. Role of saturated fat: Saturated fat has been implicated most often in the development of cancer of the prostate, high intake being correlated with sh orter survival after diagnosis of cancer.
