The best insurance against osteoporosis appears to be frequent exercise of the
bones that we want to keep strong, and a well-rounded diet that is rich in vitamins and
minerals, moderate in salt and meat, and includes a variety of calcium-containing
foods. Milk is certainly a valuable one, but so are dried beans, nuts, corn tortillas and
tofu (both processed with calcium salts), and several greens—kale, collards, mustard
greens.
