Q. Some people say that calcium doesn't really keep bones strong. How do you respond to that?
A. “There’s controversy over this—some people say calcium doesn’t actually reduce risk of fractures—but I think that, overall, the data suggest that women who eat a diet that is abundant in calcium, as well as fruits and vegetables, have reduced risk of fractures. The problem is that everybody would like to have a hero in terms of one vitamin, one mineral, or something else in the diet that’s the deciding factor, but there isn’t one single entity that helps bones. It’s not just calcium, it’s not just vitamin D. Vitamin K in fruits and vegetables, magnesium in grains—these nutrients are important for bone health too. It’s all of them put together that really create an environment that is the healthiest for bones.”
