Milk's main claim to fame may also help protect you from colon cancer. Those who took calcium faithfully for 4 years had a 36% reduction in the development of new precancerous colon polyps 5 years after the study had ended, revealed Dartmouth Medical School researchers. (They tracked 822 people who took either 1,200 mg of calcium every day or a placebo.) Though the study was not on milk itself, you can get the same amount of calcium in three 8-ounce glasses of fat-free milk, along with an 8-ounce serving of yogurt or a 2- to 3-ounce serving of low-fat cheese daily.
