We have known for years that we are supposed to drink milk to build strong bones. Vitamin D, which is found in foods like milk, fish, and even juice, prevents the brittle bones that come with osteoporosis. Now there is new evidence that Vitamin D may do even more than that.
According to Johns Hopkins researchers, who tracked more than 13,000 patients for eight years, Vitamin D is sort of an insurance policy to help ward off heart disease, diabetes, cancer, and it affects the immune system.
Dr. Michael Melamed, a Johns Hopkins Researcher at the Einstein College of Medicine, says, "It can tell a cell either to grow or to not grow and it can tell immune cells whether to turn on or not turn on. The people who had the lowest Vitamin D levels back in 1988 to 1994 had a 26% higher chance of dying".
In other words, if you have low levels of Vitamin D those immune cells may not turn on. Researchers add that while dairy products are a good source of Vitamin D, most of us get all we need from just 10 to 15 minutes a day in the sun, even if we use sunscreen. The concern is for those who spend most of their time indoors, they need to be sure that their diet includes lot of Vitamin D.
