In an animal trial, injections of high doses of vitamin C have been demonstrated to reduce tumor weight and growth rate by about 50 percent in mouse models of brain, ovarian, and pancreatic cancers.
The NIH researchers, however, tested the idea that ascorbate, when injected at high doses, may have prooxidant instead of antioxidant activity. Prooxidants would generate free radicals and the formation of hydrogen peroxide, which, the scientists hypothesized, might kill tumor cells. In their laboratory experiments on 43 cancer and 5 normal cell lines, the researchers discovered that high concentrations of ascorbate had anticancer effects in 75 percent of …read more

Data from a large, prospective epidemiologic study published in this month’s issue of The American Journal of Clinical Nutrition supports previous findings from small-scale investigations on the link between plasma vitamin C concentrations and stroke risk. They found that individuals with high concentrations of vitamin C in the blood plasma had a 42% lower risk of having a stroke compared to those whose plasma Vit C concentrations were in the lower quartile of the study population.
The next question, of course, is how to increase the circulating Vitamin C in your blood. One way is to increase your consumption of fruit …read more

If you want to make the most out of the health benefits of your green tea, pass on the milk, and add a zest of lemon instead. A preliminary study indicates that citrus juices enable more of green tea’s unique antioxidants to remain after simulated digestion, making the lemon-tea even healthier than previously thought. Using a model simulating gastric and small-intestinal digestion, it has been found that citrus juice enables more catechins to be available in the intestines for absorption. The study has been published this month in Molecular Nutrition and Food Research.
Catechins display health-promoting qualities and may be responsible …read more
