Q. If you've already developed a lot of your bone by the time you're 20 or 30, will improving your diet even make any positive difference in your bone health?
A. “You’ve probably developed most of your bone by the time you’re in your late twenties. Most of the gain is in your late teens, but we’ve seen 60- and 70-year-olds who gain some bone over time by supplementing with calcium and vitamin D and increasing exercise. Even if you’re in your twenties and thirties, you want to do everything you can to not lose bone. Developing healthier lifestyle habits is a way to maximize your peak bone density and then to minimize the loss. Once you improve your habits, you can regain some of what you’ve lost, not a lot, but some.”
