A recent study found that calcium supplements are associated with an increased risk of heart attack. Plenty has been written about the study so I won’t go into detail, but it is worth mentioning.
Remember, this study looked at calcium supplements, not calcium intake from real food.
You can get calcium from more sources besides milk and dairy products. According to Marion Nestle , eating plenty of fruits, vegetables, grains, beans and nuts can also help you get enough calcium into your body.
