Although there are quite a few myths about certain food causing acne, grapes are not one of them. If you find that you have red irritated skin blemishes after consuming grapes, it might be due to the fact that you have a mild allergy to them. Food allergies are prevalent in both kids and adults, including fruits like grapes.
Strawberries are another more common example of a food allergy which thousands of people have. The degree to which someone is allergic to grapes or any other food varies depending on the individual and it can cause oneâ€™s skin to break out into hives.
