Fried onions
Fried onions are a more concentrated form of a food that some people with histamine intolerance report reacting to, particularly in larger quantities.
Onions themselves are relatively mild, but frying changes things — the process concentrates their compounds and they tend to be eaten in larger amounts as toppings or in dishes.
-
Cooking method and quantity — raw and lightly steamed onions tend to be better tolerated by sensitive individuals; fried onions are often consumed in larger portions, which may increase the overall load
-
Portion size effect — fried onions are often eaten in larger quantities (as toppings or in dishes) than raw, which can compound the impact
Lightly sautéed or steamed onions may be worth trying as a gentler alternative.
