Numerous health benefits of grape juice are known and proven, but one of the common claims that grape juice prevents the stomach flu deserves closer scrutiny. The proponents of this theory emphasize the antiviral property of vitamin C and the ability of grape juice to change the acidity level (pH) of stomach acid. Research does not support this theory as there is no proof grape juice prevents stomach flu. Washing hands, social distancing physical activity and intake of foods naturally high in vitamin C are efficient ways of preventing the flu and boosting the immunity.
