Is Aged Cheddar Cheese High in Histamine?

High in histamine — best avoided on a low-histamine diet. Histamine forms as cheese ages: bacteria break down the milk protein and produce biogenic amines, so the longer a cheddar is matured the more histamine and tyramine it accumulates. Sharp, "extra mature" blocks are among the highest-histamine cheeses you can buy. If you are reacting to cheese, ripening time matters far more than fat content — a fresh, unaged cheese is a much safer swap.
