Two groups of rats were fed a high-salt diet, with or without grape powder (the equivalent of 9 servings of grapes daily). Two other groups were fed a low-salt diet, with or without grape powder. After 18 weeks, among rats on the high-salt diet, those given grape powder had lower blood pressure, better heart muscle function and structure, and lower markers of inflammation than those that did . . .
