MORE ABOUT VITAMIN D CONTROVERSY DOES VITAMIN D PROTECT AGAINST CANCER INFECTIONS MULTIPLE SCLEROSIS AND WHAT SCIENTISTS SAY ABOUT VITAMIN D IN HEALTH
Should you take vitamin D supplements.? Vitamin D is important for our bones and some studies suggest that a lack of vitamin D can raise the risk of cancer. But some vitamin scientists are looking at some "intriguing, if preliminary epidemiological and lab studies" that point to a role for vitamin D in combating infections,multiple sclerosis,cancer and autoimmune diseases.
A molecular geneticist, John White at McGill University said that vitamin D switches on an arm of the immune system that kills bacteria (see links below). A kind of front line response to infection. Vitamin D also has anti inflammatory effects. An article about the possible expanded roles of vitamin D in health, quotes Robert Heaney, an endocrinologist at Creighton University, "the field has just exploded." Heaney who sat on the panel that made the vitamin D dose recommendations previously, is now saying they need to be raised. However, some scientists say there is still not enough evidence that vitamin D does all the things some advocates say.
Vitamin D is found in few foods. Oily fish provides vitamin D. Milk has vitamin D added to it. Sunlight causes the synthesis of vitamin D in the skin. People who live in less sunny climes get even less vitamin D. In general getting vitamin D just from food is a tricky proposition.
The Canadian Cancer Society has recommended that people in Canada take vitamin D. Specifically, adults living in Canada should consider taking vitamin D supplementation of 1,000 international units (IU) a day during the fall and winter. Adults at higher risk of having lower vitamin D levels should consider taking vitamin D supplementation of 1,000 IU/day all year round. This includes people who are older; with dark skin; who don't go outside often, and who wear clothing that covers most of their skin.
