Abstract

The free radical theory of aging posits that the accumulation of macromolecular damage induced by toxic reactive oxygen species plays a central role in the aging process. Therefore consumption of dietary antioxidants appears to be of great importance. Wheat germ have strong antioxidant properties. Aim of this study is investigate the effects of a wheat germ rich diet on oxidative mtDNA damage, mtDNA copy number and antioxidant enzyme activities in Drosophila. Current results suggested that dietary wheat germ enhances the activities of antioxidant enzymes in Drosophila. There was no statistically difference in mtDNA damage and mtDNA copy number results of “Wheat Germ” and “Refined White Flour” feed groups. mtDNA damage slightly increased with aging in both groups but these changes were no statistically different.
