You need more than calcium to ward off osteoporosis and bone fractures: you also need vitamin D. And new research shows that vitamin D may do more than help keep bones healthy. Tissues in the skin, brain, pancreas and elsewhere rely on this vitamin, too, to stay healthy. In addition, getting adequate amounts of vitamin D may bolster your immune system and even prevent colon cancer. The body synthesizes vitamin D from sunlight, and it is found naturally in oily fish such as salmon, mackerel and herring; liver; egg yolks; and butter.
