Does calcium work?

A new analysis of all kinds of studies on the use of calcium to prevent fractures is just out in the American Journal of Clinical Nutrition. The results? “calcium intake is not significantly associated with hip fracture risk in women or men…[results] show no reduction in hip fracture risk with calcium supplementation, and an increased risk is possible.” It sure would be nice if it were that easy to prevent fractures but bone strength requires a good diet containing ALL nutrients, not just calcium (with or without vitamin D), as well as plenty of physical activity, so these results should not come as a surprise. The bottom line: eat healthfully and move!
