The participants also showed significant improvement in their lipid profile.

Grapes to Protect the Heart: Prevent Atherosclerosis
Red grapes are packed with bioflavanoids, which are potent anti-oxidants that have a strong action against plaque formation within the arteries. Resveratrol, another polyphenol is known to have a protective action on the arterial walls and prevents atherosclerosis.
Another nutrient called pterostilbene, directly affects the enzymes that regulate cholesterol and triglyceride levels in the blood. Grapes are effective in regulating cholesterol levels in blood.
Grapes are also very effective in management of peripheral venous disorders like varicose veins. Bioflavanoids prevent the clotting of platelets and thereby prevent clot formation and aid in reducing venous congestion.
