But to be most effective, that calcium has to come from sources that aren't high in fat. Nonfat dairy products, such as skim milk or nonfat yogurt, and supplements are most effective. Otherwise, the fat negates the good effect of the calcium. Another study found that calcium could lower the risk for colorectal cancer. In this study, people who had been treated for colorectal polyps were less likely to have the polyps return if they took daily calcium supplements.
Polyps are benign tumors in the colon that can develop into cancer.
By reducing the growth of polyps, calcium could lower cancer risk. The researchers believe calcium could also prevent the growth of polyps in people who haven't been treated for them. Doctors at UT Southwestern Medical Center at Dallas say most people don't get all the calcium they need. Try incorporating nonfat dairy products into your diet, or look for other sources, like calcium-fortified foods and dietary supplements.
