High Histamine Foods List (What to Avoid)

A good way to ease into a low histamine diet is to start by eliminating the worst culprits, that is, the foods which most directly raise your histamine levels: the high histamine foods. Whether you have MCAS, mastocytosis, or a more general histamine intolerance, cutting out high histamine foods is essential for managing your symptoms.

Most food lists out there just dictate what to eat and what to avoid, but rarely do they dig into why there are so many high histamine foods out there. The secret is: most of what we label as high histamine foods are actually low in histamine.

But they’re foods which have some other characteristic(s) that make them trigger reactions in most people with histamine issues. This is actually good news for you.

It means that even a couple weeks into the diet, you may be able to start reintroducing some high histamine foods— if you discover the root cause of your histamine intolerance.

What Makes Foods High Histamine?

If your symptoms aren’t very bad or you’re trying to ease some seasonal allergy woes, you can just start by emphasizing lower histamine foods, slowly & eventually replacing each of these high histamine foods.

But beyond the foods with the highest histamine levels, I want to dig into four other types of foods which you’ll find on the list below. Each of these types of foods can raise or abnormally sustain your histamine levels.

You can find a more in-depth look at what to eat on a low histamine diet in my low histamine foods list, but looking at it directly, there are foods which:

• •contain high levels of histamine
• -contain high levels of other biogenic amines
• +maintain existing histamine levels (prevent the clearing of histamine by DAO)
• *theoretically “release” histamine from other foods (histamine liberators; unproven)
• ~increase intestinal inflammation (or increases “permeability“)

Once you figure out why you’re so sensitive to histamine, you may find that you’re able to reintroduce certain foods more quickly due to why they were initially eliminated. I’ve marked the 5 reasons why a food may need to be avoided on each food below, according to the symbols I’ve added next to each of the reasons listed above.
