Grapes Histamine Information

Grapes, primarily red and black variations, contain an antioxidant called quercetin that behaves as a natural antihistamine. Quercetin blocks the release of histamine thus reducing allergy symptoms and the potential for a histamine reaction. It may be particularly useful for those with histamine intolerance, or high histamine levels, considering it has a natural effect of keeping histamine levels in check. However, large quantities of grapes may increase total histamine in the body as grapes are naturally high in histamines. Concerning the other foods and products mentioned and their impact on histamine levels: Red wine and French champagne are known to have higher histamine content due to fermentation, especially if made from red grapes. Yeast in baked goods, and mushrooms too, contribute to higher histamine levels. Cheese, especially aged and hard cheese, along with yogurt and buttermilk, contain bacteria. These bacteria produce histamine during the fermentation process. Similarly, typical vinegar and vinegar-based products like pickles and mustard, carry higher histamine content. Histamine levels in the body increase significantly when processed, preserved, or smoked meats are consumed, such as ham and salami. The same applies to certain fish products, particularly smoked fish and canned fish. Tomatoes and tomato products like ketchup and pizza have also been identified as histamine-rich foods. Certain foods delay breakdown of histamine prolonging its effects. This includes pineapple, papaya, cocoa products, nuts, alcohol, green and black tea, and energy drinks. Histamine libera-tors, such as cocoa products, citric fruits, mushrooms, certain nuts, and additives like gelatine and some preservatives promote the release of histamine in the body causing an increase in histamine levels. Every individual reacts uniquely to different foods—the list above applies generally, but sensitivities vary on an individual level.
