Have you heard of anti-histamine foods? When you have Mast Cell Activation Syndrome or MCAS, the key to success is to find the foods you can tolerate. Foods that are high in histamine should generally be avoided, but your individual constitution will determine what you can tolerate. Foods that are low in histamine are generally considered safe. And then there are foods that actually lower histamine or anti-histamine foods. When you include anti-histamine foods in your meals you can ameliorate some of the negative effects of eating higher histamine foods.
