Yes, mango is low histamine. It’s also a natural antihistamine and a great source of vitamin C, and a decent source of vitamin A and dietary fiber. However, mangoes are also quite high in sugar; therefore you shouldn’t have more than one mango without eating it alongside another high protein or high fiber food. Some sources have noted that mango may be a histamine liberator, but even the concept of a “histamine liberator” is quite muddled. In fact, mango’s vitamin C content is believed to be what makes it a natural antihistamine, as vitamin C is a mast cell-stabilizer.
