Calcium and Cancer

Your mom always told you to drink your milk, and now there's reason to heed her advice. According to new research, women who get the most calcium daily (from food sources such as low-fat dairy) slashed their odds of developing stomach, oesophageal, and colon cancers by about 23 percent.

"Calcium tends to build up bile and fat in the digestive tract," says study author Yikyung Park. "That may prevent them from damaging the protective lining, which can up the risk for cancer."
