scientists from the U.S. recently reported in American Journal of Clinical Nutrition that low zinc supply with increased wear of the DNA strands in peripheral blood cells is accompanied, during the normalization of zinc levels the breaking of the strands is reduced again. About two billion people worldwide suffer from a lack under zinc . A deficiency is implicated in several chronic diseases, including cancer, combined. The protective effect of zinc on its antioxidant properties and ability to the DNA repair, returned.
During the study, nine healthy men in a controlled diet, so that the scientists were able to zinc supply to manipulate. In the first 13 days, subjects received daily 11 mg zinc , which ensured an adequate zinc status. Then the subjects were given 42 days no zinc . At 56 Day of the study, participants received 11 mg for 18 days again zinc daily, with the first seven days extra zinc was administered. The total time taken from regular blood samples, allowing the blood cells to DNA damage are investigated. The results showed that had risen the end of the zinc-free period, the damage to the DNA strands in comparison to the initial study by 57%. At the end of the study, when the zinc level was raised again, the blood samples showed a 39.9% lower injury and the fact that the damage was reversible.
The authors concluded that: 'All in all, the data suggest that the influence of zinc status of DNA damage in peripheral blood cells, and that an adequate zinc status on DNA integrity in humans may be essential. "
