Opening Salvo of the Vitamin D Wars?
Some news in the mainstream online sources of a new study which appears
to be casting doubt on the role of vitamin D and cancer.
This article mentions the positive markers for
preventing colon cancer but suggests nothing positive for
other cancers. The article is suitably vague about what constitutes
too much vitamin D intake. In fact, it mentions nothing in terms of
how much vitamin D a person could synthesize in direct sunlight
on a bright summer day nor the amount required to show toxic
side effects. Articles like this will leave people to rely on
the antiquated RDIs of the FDA which are far too low for
vitamin D.
As an example of what constitutes healthy vitamin D intake as well as other vitamins, here's a news bulletin from the Orthomolecular News Service that came out this week (reproduced below). Compare with the current US FDA RDI which is 400 IU a day.
I also noticed this past weekend that you can get Vitamin D at Walmart. There are 1000 IU capsules of Vitamin D3 available.
Doctors Say, Raise the RDAs Now (OMNS October 30, 2007) The US Recommended Daily Allowance/Daily Reference Intakes are too low and most should be raised immediately, says an independent panel of physicians, academics and researchers. In a statement this week, the Independent Vitamin Safety Review Panel said: "Government-sponsored nutrient recommendations, such as the US RDA/DRIs, are not keeping pace with recent progress in nutrition research. While current official recommendations for vitamin A, iron, calcium, and some other nutrients are generally adequate, the public has been asked to consume far too little of many other key nutrients. Inadequate intake, and inadequate standards to judge intake, have resulted in widespread nutrient inadequacy, chronic disease, and an undernourished but overweight population." Citing a large number of physician reports and clinical studies, the IVSRP called for substantial increases in daily intake of the B-vitamins, vitamins C, D and E, and the minerals selenium, zin! c, magnesium and chromium. "Raising the RDA/DRI will save lives and improve health," the Panel said. "Clinical and sub-clinical nutrient deficiencies are among the main causes of our society's greatest healthcare problems. Cancer, cardiovascular disease, mental illness, and other diseases are caused or aggravated by poor nutrient intake. The good news is that scientific evidence shows that adequately high consumption of nutrients helps prevent these diseases." Specifically, the IVSRP called for a new standard, an Optimum Health Requirement, recommending daily adult consumption of nutrients in the following higher quantities: Vitamins B-1 Thiamine: 25 mg B-2 Riboflavin: 25 mg B-3 Niacinamide: 300 mg B-6 Pyridoxine: 25 mg Folic acid: 2,000 mcg B-12 Cobalamin: 500 mcg C: 2,000 mg D3: 1,500 IU E as natural mixed tocopherols: 200 IU Minerals Zinc: 25 mg Magnesium: 500 mg Selenium: 200 mcg Chromium: 200 mcg The Panel concluded by stating: "In the past, over-conservative government-sponsored standards have encouraged dietary complacency. People have been led to believe that they can get all the nutrients they need from a 'balanced diet' of processed foods. That is not true. For adequate vitamin and mineral intake, a diet of unprocessed, whole foods, along with the intelligent use of nutritional supplements, is more than just a good idea: it is essential."

Orthomolecular medicine uses safe, effective nutritional therapy to fight illness.
