Calcium supplements are the fourth most consumed supplement in the United States. The current recommendation is 1200mg per day; this is equal to about 4 glasses of milk per day. But where did this number come from? How was it decided that everyone needed to be taking in so much calcium? There was a study done in 1986 that demonstrated that taking 1200mg of supplemental calcium did indeed increase bone density. This bit of news was taken up by the media and supplement companies and voila- a new recommendation to help promote dense bones. Unfortunately it took 10 years before someone asked the question of whether or not taking that much calcium decreased fractures. A 12 year study in 1997 that followed 77,000 women showed that women who drink 2 or more glasses of milk are actually almost 50 percent higher risk of fracture than those who don’t drink milk.
It turns out that while supplemental calcium may increase bone density some, it also makes bones more brittle. The highly promoted idea that milk builds “strong bones” refers to the prevention of osteoporosis. We’ve been lead to believe that drinking milk and eating dairy products is the best way to do this. In fact, the opposite seems to be true. A balanced intake of minerals cannot occur when the diet emphasizes dairy. Dairy’s high calcium content causes relative deficiencies in magnesium and other bone-building minerals, and its high phosphorus content reduces calcium availability. Healthy bones come from a balanced intake of all the bone minerals, including calcium from food, exercise (especially weight lifting) and vitamin D. Here are some great foods and their calcium content.
