DAO Deficiency

What we write about here

This is where we write about histamine and about the enzyme that breaks it down: which foods build it up, why the symptoms turn up in places as different as the head, the skin and the gut, and what the scientific literature actually says when you read the whole of it. There are long reads, study summaries and low-histamine recipes meant for eating normally rather than counting amines all day. If you have just arrived, two good places to start are the food list and the signs of DAO deficiency.
