An American prospective study involving more than 3600 men and 10 years of follow-up-for the first National Health and Nutrition Examination Epidemiologic Follow-up Study (NHEFS)-found that those with the highest intakes of dairy were more than twice as likely to develop prostate cancer than men with the lowest intakes.
However, when the researchers looked at the individual dairy products consumed, they found that the risk was higher only with low-fat milk-and not for whole milk or any other dairy. In fact, whole milk had a slight-albeit statistically not significant-protective effect (Am J Clin Nutr, 2005; 81: 1147-54).
