Effects and mechanisms of antioxidant-rich functional beverages on disease prevention

There has been growing attention of the key role of beverages as they deliver health benefits beyond the basic nutritional functions. Functional beverages are an excellent source of functional components including vitamins, minerals, polyphenol, amino acids, and bioactive compounds and their mechanisms of action included antioxidant effects. The antioxidant-rich beverage protects the body against oxidative stress. Oxidative stress may lead to elevate reactive species and a decrease in antioxidant defenses, resulting in chronic diseases like cardiovascular disease, cancer, type-2 diabetes, and neurodegeneration. Consumption of natural compounds with an antioxidant profile may be a preventive substitute. Pomegranate, grapes, tomato, apple, or some other fruit and vegetables juices are well known to possess antioxidant activities. This review illustrates the recent studies on the antioxidant and radical scavenging activity of fruit and vegetable juices supplementation and their role in disease prevention, and a special attention is paid to the mechanisms of action.
