Here’s a very informative study, that shows how results can lead to unfounded conclusions and mislead you into a false assumption. While there’s a voluminous number of scientific studies that clearly demonstrate the role vitamin deficiency states play in the development of cancer, this study suggests otherwise. Research studies from time to time have been reported that conflict with the documented protective role vitamins in our food and supplements play in general and antioxidants in preventing cancer.
Initial review of the information caused me to pause and wonder about the differences, and it became immediately evident to me.
A study conducted at Cedars-Sinai Heart institute in Los Angeles, California, by its Director, Dr. Eduardo Marban, found while trying to lower the genetic changes that happen when attempting to multiply human heart stem cells.
They found that high doses of antioxidant supplements, such as vitamin C and E, not foods may increase cancer risk.
Because heart stem cells growing in higher concentrations of oxygen caused more abnormalities, the researchers attempted to stop the problem triggered by oxidation via adding high doses of antioxidants.
The study published online in the journal Stem Cells found there is a danger zone for cells exposed to anti-oxidants to develop genetic abnormalities that predispose to developing cancer.
“Taking one multivitamin daily is fine, but a lot of people take way too much because they think if little is good, a lot must be better. If you’re taking 10 or 100 times the amount in a daily multivitamin, you may be predisposing your cells to developing cancer, therefore doing yourself more harm than good,” Dr. Marban said.
The study reports that the stem cells were exposed to 20 per cent oxygen, but cells growing in human tissue are exposed to just 3 to 5 per cent oxygen. This is critical, because the research findings do not reflect what happens in the human body under normal conditions. Also, our cells are exposed to numerous factors, including our emotions, varying levels of circulation (oxygen and nutrients), environmental factors, toxins, etc., that all play a part in our risk of developing cancer.
