Calcium Supplementation Linked To Increased Risk of Colon Polyps
Daily calcium supplements are linked to an increased risk of colon polyps. 2,000 participants (aged 45 to 75), all with a history of polyps, were randomly assigned to take a daily calcium supplement, a daily vitamin D supplement, both, or neither for 3 or 5 years.

If you need additional calcium, consider these sources first: white beans, figs, Bok Choy, kale, black eyed peas, almonds, oranges, turnip greens, sesame seeds, and seaweed.
