Serving size, prep, and portion notes for ham
Ham is cured pork, and the curing is exactly what turns it into a trigger food. It is very high in nitrites from the curing salts and high in histamine that builds up as the meat is salted and aged, so deli ham and sliced sandwich ham are common reasons for flushing, headaches or a blocked nose. Fresh pork does none of this: it is the cure, not the pork, that causes the problem.
Watch for
Very high in nitrites from the curing salts (sodium nitrite), a frequent trigger for headaches and facial flushing / High in histamine, because salting and slow aging let histamine accumulate, so cured ham hits harder than fresh meat / Moderate tyramine plus a mild histamine-releasing effect, which can stack on top of the histamine already in the meat / Usually carries added sulfites for colour and shelf life, another common sensitivity in preserved meats
