A new study shows vitamin C's cancer-fighting properties. Reuters reports:
The new research, published in the journal Cancer Cell, supported the general notion that vitamin C and other so-called antioxidants can slow tumor growth, but pointed to a mechanism different from the one many experts had suspected.And, it seems Vitamin E may reduce blood clots in women. More from Reuters:
The researchers generated encouraging results when giving vitamin C to mice that had been implanted with human cancer cells -- either the blood cancer lymphoma or prostate cancer. Another antioxidant, N-acetylcysteine, also limited tumor growth in the mice, the researchers said.
Antioxidants are nutrients that prevent some of the damage from unstable molecules known as free radicals, created when the body turns food into energy. Vitamin C, vitamin E and beta-carotene are among well-known antioxidants.
"The data indicated that, in general, women taking vitamin E were 21 percent less likely to suffer a blood clot," the American Heart Association, which published the finding in its journal Circulation, said in a statement.To round out the good news, according to Reuters Vitamin D may cut risk of early death. Look:
"This is an exciting and interesting finding, but I don't think it's proven," Dr. Robert Glynn of Harvard Medical School said.
The American Heart Association generally does not recommend antioxidant vitamins such as vitamin E for the prevention of cardiovascular diseases or conditions, which include blood clots.
The study by Glynn and his colleagues reviewed data from 39,876 women aged 45 and older taking part in the Women's Health Study. They were given either 600 international units of natural source vitamin E or a placebo.
"Intake of ordinary doses of vitamin D supplements seems to be associated with decreases in total mortality rates," said Philippe Autier of the International Agency for Cancer Research in France and Sara Gandini of the European Institute of Oncology in Milan.Want to know more about these vitamins and where to get them?

The reasons why were not clear but the researchers suggested the vitamin might block cancer cells from spreading or boost the immune system.
They did not conduct the studies themselves but did what is called a meta-analysis by reviewing 18 separate trials involving nearly 60,000 patients. The doses averaged 528 international units, within the range of most commercially available vitamin D supplements.
Food supplies us with both nutrients and calories (energy). All calories come from only three elements: carbohydrates, fats, and proteins. Nutrients are derived from noncaloric food factors — including vitamins, minerals, fibers, and phytochemicals. These noncaloric nutrients are vitally important for health…
