Removing dairy products from your diet may lower your risk of certain cancers, according to a study published online in the British Journal of Cancer. Researchers followed 22,788 lactose intolerant participants from Sweden. They also monitored cancer rates of their immediate family members. The incidence rates for lung, breast, and ovarian cancers decreased among the lactose intolerant. Family members and the general Swedish population who included dairy in their diet did not experience the same reduction in cancer risk. Researchers suspect the avoidance of high amounts of saturated fat and hormones found in dairy products may account for the decreased risk.
