18 Foods Research Links to Increased Cancer Risk

6. Dairy products

Research into the effects of dairy products on cancer risk is mixed. Some studies have determined that dairy can be connected to an increased risk of some cancers, while others have determined it may have protective qualities. For example, research into the effects of dairy products on breast cancer has yielded mixed results. Some research suggests that dairy's vitamin D and calcium can protect against breast cancer. At the same time, other studies show that the increased intake of saturated fats from dairy products can increase the risk of breast cancer, as can the compounds and pollutants found in milk, including estrogen.
