How Grapes Protect Your Heart
May 14, 2009
A diet enriched by grapes may prevent the downhill sequence of heart failure after years of high blood pressure. A study suggests that grapes may prevent heart health risks beyond the simple blood pressure-lowering benefits that come from a diet rich in fruits and vegetables.
The heart-healthy benefits of grapes may be the result of the phytochemicals (naturally occurring antioxidants) activating a protective process in the genes that reduces damage to the heart muscle.
Researchers studied the effect regular table grapes had when added to the diets of rats. After 18 weeks, the rats that received the grape-enriched diet powder had lower blood pressure, better heart function, and fewer signs of heart muscle damage.
