To support bone strength, stave off osteoporosis and keep your muscles and joints working well, it’s important to get enough calcium in your diet. But that’s where most of it should come from: your diet. Don’t rely on just multivitamins and calcium chews. Fat-free milk, cheese and yogurt, dark leafy greens, sardines, soybeans, broccoli, sesame seeds and almonds all offer this vital mineral. Aim for 1,300 mg a day, with no more than 50 percent from supplements. And don’t forget to move. Exercise, especially resistance work, is key to building healthy bones.
