Grapes Up-Regulate Genes To Make Glutathione Antixoidant
- While fruits and vegetables have been extolled for years as heart-healthy antioxidants the direct antioxidant benefits of their chemicals have been exaggerated. Lots of healthy foods deliver much of their benefit by causing alterations in metabolism. To do that they must cause changes in genetic regulation. Here is some research that shows grapes turn on genes that boost an internally synthesized antioxidant called glutathione. A study appearing in the Journal of Nutritional Biochemistry¹ demonstrates that grapes are able to reduce heart failure associated with chronic high blood pressure (hypertension) by increasing the activity of several genes responsible for antioxidant defense in the heart tissue. Grapes are a known natural source of antioxidants and other polyphenols, which researchers believe to be...
