Oatmeal
Plain oatmeal has no significant histamine content and is well-tolerated by most people with histamine sensitivity.
Oatmeal is a minimally processed whole grain with no fermentation step and no known histamine-raising properties.
-
Clean and simple — rolled or steel-cut oats don't contain histamine, and nothing in standard processing introduces it
-
Toppings change things — plain oatmeal is easy to handle, but common additions like dried fruit, nut butters, or flavored syrups may be worth watching
Building a plain oatmeal base and adding low-histamine toppings gives you a lot of flexibility.
