Vitamin D is the new hot nutrition topic of this decade. Adequate Vitamin D circulating in the blood is important not only for bone health (calcium relies on vitamin D to help it travel to the parts of the body that need it) but also insufficient D has been implicated in a host of health problems such as high blood pressure and heart disease.
Your body can make vitamin D from sunlight, but most of us can’t get enough from that route, so you'll want to get most of your vitamin D from food and supplements. The best sources are fatty fish including salmon (wild), herring, mackerel, and sardines; milk (fat-free, 1% low-fat), soy milk, and fortified yogurt. Because few foods are rich in vitamin D, you may need to take a supplement) in order to take in 1000 IU of vitamin D daily. Ask your doctor to test your D level and if it’s low, discuss supplementing.
