Anticancer Research published by the Research explains that women suffering from breast cancer but has a high content of vitamin D in the blood stream will have a higher life expectancy than those who do not.
" Vitamin D is entered in the bloodstream of patients with breast cancer will repair normal cells damaged by the effects of cancer cells. Vitamin D is also able to fight the cancer cells in the body so as to extend the life expectancy of cancer patients, " said The study's authors, Dr. Heather Hofflich, a professor of medicine at the University of California San Diego.
Vitamin D can be produced naturally in the body by processing the sunlight on the body. But besides these ways, vitamin D can also be obtained from foods that contain vitamin D such as milk, cereals, fish, and fish oil.
Vitamin D is a group of fat-soluble secosteroids responsible for enhancing intestinal absorption of calcium, iron, magnesium, phosphate and zinc. In humans, the most important compounds in this group are vitamin D3 (also known as cholecalciferol) and vitamin D2 (ergocalciferol). Cholecalciferol and ergocalciferol can be ingested from the diet and from supplements. The body can also synthesize vitamin D (specifically cholecalciferol) in the skin, from cholesterol, when sun exposure is adequate (hence its nickname, the "sunshine vitamin").
Although vitamin D is commonly called a vitamin, it is not actually an essential dietary vitamin in the strict sense, as it can be synthesized in adequate amounts by most mammals exposed to sunlight. A substance is only classified as an essential vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from its diet. In common with other compounds commonly called vitamins, vitamin D was nevertheless discovered in an effort to find the dietary substance lacking in a disease, namely rickets, the childhood form of osteomalacia. Additionally, like other compounds called vitamins, in the developed world, vitamin D is added to staple foods, such as milk, to avoid disease due to deficiency. *wiki*
