Vitamin D: importance in the prevention of cancers, type 1 diabetes, heart disease, and osteoporosis.

The purpose of this review is to put into perspective the many health benefits of vitamin D and the role of vitamin D deficiency in increasing the risk of many common and serious diseases, including some common cancers, type 1 diabetes, cardiovascular disease, and osteoporosis. Numerous epidemiologic studies suggest that exposure to sunlight, which enhances the production of vitamin D3 in the skin, is important in preventing many chronic diseases. Because very few foods naturally contain vitamin D, sunlight supplies most of our vitamin D requirement.

25-Hydroxyvitamin D [25(OH)D] is the metabolite that should be measured in the blood to determine vitamin D status. Vitamin D deficiency is prevalent in infants who are solely breastfed and who do not receive vitamin D supplementation and in adults of all ages who have increased skin pigmentation or who always wear sun protection or limit their outdoor activities. Vitamin D deficiency is often misdiagnosed as fibromyalgia.

A new dietary source of vitamin D is orange juice fortified with vitamin D. Studies in both human and animal models add strength to the hypothesis that the unrecognized epidemic of vitamin D deficiency worldwide is a contributing factor of many chronic debilitating diseases. Greater awareness of the insidious consequences of vitamin D deficiency is needed. Annual measurement of serum 25(OH)D is a reasonable approach to monitoring for vitamin D deficiency. The recommended adequate intakes for vitamin D are inadequate, and, in the absence of exposure to sunlight, a minimum of 1000 IU vitamin D/d is required to maintain a healthy concentration of 25(OH)D in the blood.

  • Vitamin D is better than Vitamin C!

  • It depends what you're using them for. Different vitamins perform different functions in the body. Vitamin C works more on the immune system.

  • This is great... thanks

  • You make vitamin D in the skin. But taking it orally is VASTLY different. I did my masters thesis in organic chemistry on hormone mimics and showed conclusively that ingestion of hormones is in fact toxic, especially vitamin D! You are erroneously using skin production as a measure of oral toxicity. Absurd and dangerous. What if we swallowed estrogen and estrogen mimics? We'd get sick. Same with D! We bypass our innate protection. Google "Stink Award" online.

  • @rgzdev i agree,great video but that god part is just ridiculous

  • "Who do you want to believe God or the government"

    Way to throw your credibility out through the window! Since he is basing his estimates of of Vitamin D requirements on the actual production levels of the human body, it would make more sense to credit *evolution* than god, which would be true even if a god(s) existed.

    But that would miss the point of proselytizing.

  • google codex alimentarius for info on our future and the vitamin supply.

  • Stopes left most of her estate to the Eugenics Society, an organization that shared her passion for racial purity and still exists today under the new name The Galton Institute. The society has included members such as Charles Galton Darwin (grandson of the evolutionist), Julian Huxley and Margaret Sanger.

  • Stopes also attended the Nazi congress on population science in Berlin in 1935, while calling for the compulsory sterilization of the diseased, drunkards, or simply those of bad character. Stopes acted on her appalling theories by concentrating her abortion clinics in poor areas so as to reduce the birth rate of the lower classes.
