Dairy products may increase your risk of death from prostate cancer, according to a study published in the International Journal of Cancer. Researchers monitored the dairy intake of 926 men diagnosed with prostate cancer as part of the Physician’s Health Study for 10 years. Those who consumed three or more servings of dairy products a day increased their risk for overall death by 76 percent and had a 141 percent higher risk for death due to prostate cancer compared to those who consumed less than one serving. Both high- and low-fat dairy products were associated with increased mortality. Researchers suspect hormones, saturated fat, and dairy calcium as possible mechanisms for the increased risk.
