High-Histamine Foods

Histamine accumulates in food through fermentation and protein degradation. The shared characteristic of all high-histamine foods is fermentation or extended protein breakdown, both of which generate histamine directly. Histamine-rich foods can interfere with fasting tolerance in histamine-intolerant people. Leftover proteins accumulate histamine because bacterial breakdown of protein generates histamine over time. People with histamine intolerance may experience cravings, irritability, or difficulty fasting comfortably after eating histamine-rich foods. Fermented tofu, pork, and processed lunch meats are examples of histamine-rich foods that could make fasting harder for some people.
