Please review your daily intake of Vitamin D
Wednesday, February 20th, 2008Try and read this article on Vitamin D by the dean of health and fitness writers, Jane E. Brody from The New York Times. She recaps the current thinking about the benefits and proper doses of Vitamin D.
Here are some of the key points from her article:
Many Doctors and researchers now believe that the current recommended daily allowances (RDAs) of Vitamin D are too low.
You can get your Vitamin D through sunlight, eating certain foods rich in D or through supplements.
Skin exposure to the suns UV rays (the same ones that cause sunburn) forms Vitamin D.
Other sources of Vitamin D are fortified milk, juices and certain foods such as the oily fishes. Some vitamins contain D, but not all. Check your labels.
It takes a quart of fortified mild a day to reach the current RDA of 400 international units (IUs).
Researchers now believe that 700-800 IUs per day will significantly reduce risk of bone fractures
Animal studies show that Vitamin D reduces tumors.
Observational studies in people show that low levels of Vitamin D are linked to the increased occurrence of many types of cancer including breast, stomach, bladder, pancreas and uterus as well as Hodgkins Lymphoma and multiple myeloma. A recent double blind study showed that those taking 1000 IUs of D had 80% less chance of cancer than those that did not. Diabetes and MS have also been linked to low levels of D.
It is unclear what the maximum safe dose of Vitamin D is as reliable studies are rare.
