Chromium 6: A Killer Compound With An Improbable Trigger
Even miniscule amounts of chromium 6 can cause cancer. Blame that do-gooder nutrient, vitamin C.Brown University researchers have discovered that naturally occurring vitamin C reacts inside human lung cells with chromium 6, or hexavalent chromium, and causes massive DNA damage. Low doses of chromium 6, combined with vitamin C, produce up to 15 times as many chromosomal breaks and up to 10 times more mutations - forms of genetic damage that lead to cancer - compared with cells that lacked vitamin C altogether.
Chemistry sure is hard.
AP Wire | 02/27/2007 | Antioxidants don’t help you live longer
Antioxidant vitamins taken by tens of millions of people around the world won’t lead to a longer life, according to an analysis of dozens of studies that adds to evidence questioning the value of the popular supplements. The large review of separate studies on thousands of people found no long-life benefit from vitamins A, E and C and beta carotene and selenium.
On the other hand, they might kill you.
Then again, there is no guarantee the study is correct.
Dr Ioannidis wrote: “Published research findings are sometimes refuted by subsequent evidence, with ensuing confusion and disappointment.” He argued that there is increasing concern that in modern research, false findings may be the majority or even the vast majority of published research claims, and went on to try and prove that most claimed research findings are false.
However, in this week’s PLoS Medicine, Ramal Moonesinghe (US Centers for Disease Control and Prevention) and colleagues demonstrate that the likelihood of a published research result being true increases when that finding has been repeatedly replicated in multiple studies.
So there you have it.
