(NaturalNews) 30 years ago the famous Nobel laureate Linus Pauling said that vitamin C supplements can prevent cancer, a highly controversial statement at the time. Now a team of Johns Hopkins scientists have shown that vitamin C stops the growth of some tumors in mice.The StudyThe study was lead by Chi Dang, M.D., Ph.D., professor of medicine and oncology and Johns Hopkins Family Professor in Oncology Research. Their work is detailed in Cancer Cell, Volume 12, Issue 3, 230-238, 11 September, 2007. They found that the antioxidants' actual role may be to destabilize a tumor's ability to grow under conditions where there isn't enough oxygen to feed it. The conventional belief is that vitamin C helps prevent cancer growth by grabbing up volatile oxygen free radical molecules and preventing the damage they do to our DNA. "The potential anticancer benefits of antioxidants have been the driving force for many clinical and preclinical studies," Says Dang. "By uncovering the mechanism behind antioxidants, we are now better suited to maximize their therapeutic use."
Matti Narkia on 25 Feb 09Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism (1). Vitamin D3 (cholecalciferol) can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight, or it can be obtained from the diet. Plants synthesize ergosterol, which is converted to vitamin D2 (ergocalciferol) by ultraviolet light. Vitamin D2 is less active in birds than vitamin D3 and may also be less active in humans (2). When exposure to UVB radiation is insufficient for the synthesis of adequate amounts of vitamin D3 in the skin, adequate intake of vitamin D from the diet is essential for health.
