Vitamin D deficiencies at epidemic levels, says new study

(NaturalNews) Vitamin D is an amazing nutrient that protect the body from all sorts of diseases and problems. Researchers continually uncover new links between lack of vitamin D and disease, illustrating the fact that it is vital to good health. However recent studies have also found that most people are deficient in vitamin D.

A team of doctors from the McGill University Health Centre in Canada was surprised to find that about 59 percent of people evaluated were deficient in vitamin D and about 25 percent were severely deficient. Published in the Journal of Clinical Endocrinology and Metabolism, the study is allegedly the first to illustrate a definitive link between vitamin D deficiency and an accumulation of fat in muscle tissue.

"Because it [vitamin D deficiency] is linked to increased body fat, it may affect many different parts of the body. Abnormal levels of vitamin D are associated with a whole spectrum of diseases, including cancer, osteoporosis, and diabetes, as well as cardiovascular and autoimmune disorders," explained Dr. Richard Kremer, lead investigator of the study.

What can you do about it?
1) Get 15 - 20 minutes of sunlight a day.
2) The best form of vitamin D is D3, or cholecalciferol, because it is the precursor to the type created by the body from sunlight exposure. Vitamin D3 can be safely taken at amounts much higher than the RDA guidelines. The article says the recommended daily allowance (RDA) of vitamin D is between 200 and 400 international units (IU) per day, depending on age. Recent studies are showing that these recommendations are too low to maintain optimal health. Some are suggesting that these guidelines be updated to amounts upwards of 1,000 IU per day, including the Canadian Cancer Society.
3) Some foods contain vitamin D, but most people do not consume enough vitamin D-rich food to obtain adequate amounts of it.
