Health benefits of grape juice

Grapes are an excellent source of health-promoting flavonoid. The stronger the color of the grape, the higher the concentration of flavonoids.

Flavonoids of polyphenols in grape juice are reported to reduce low density lipoprotein (LDL) oxidation and improve blood circulation.

Expert says that flavonoids in purple grape juice are among the most powerful antioxidants around – may be even better than vitamins C or E.

Grape seed extracts, which are rich in flavonoids known as procyanolic oligomers, are widely used in treating varicose veins and other venous disorders.

A study published in the American Journal of Clinical Nutrition showed that purple grape juice has the power to reduce LDL cholesterol and triglycerides – both of which help to lower risk for heart disease.

A study at the University of Wisconsin found that when purple grape juice was given to laboratory animals, abnormal clotting was significantly reduced. It shows that flavonoids reduce the ‘stickiness’ of blood-clotting cells, or platelets which lowers the risk of coronary heart disease and heart attack.

Another of the key components of grapes is resveratrol. Resveratrol belongs to a group of compounds called phytoalexins that plants produce in self-defense against environmental stressors, such as adverse weather or attack by insect or organisms.

Resveratrol acts as an antioxidant and has also been shown to reduce the buildup of plaque in arteries.
