Is banana high in histamine?

Banana is mostly low in histamine: none was detected in tested bananas, but they contain putrescine, a related amine, and 4 of 10 published low-histamine diets exclude them.

Fine for many people. Rated 1 of 3. Measured in lab studies.

Why sources disagree. Bananas had no detectable histamine in tests, but they carry notable putrescine, an amine some researchers think competes with histamine for the DAO enzyme. Four of ten published diets exclude them.

mg/kg = milligrams of histamine per kilogram of food. "Not detected" means below the laboratory's detection limit.

How freshness and processing change it

No study we found measured histamine or putrescine as bananas ripen, so advice to eat only green or only ripe bananas is untested. Our rating is for fresh bananas; banana chips and dried banana were not measured.

Why we rate banana 1

Bananas are a good example of why "histamine" lists are really lists of several different things. Measured directly, bananas contain no detectable histamine: a University of Barcelona team tested eight bananas sold in Spain and none had any. What they did contain was putrescine, a related amine, at an average of 37.94 mg/kg and up to 49.49 mg/kg. Among the fruits the team measured, only citrus fruit had more.

Putrescine matters because some researchers think it competes with histamine for diamine oxidase (DAO), the gut enzyme that breaks histamine down. If that is true, a food rich in putrescine could let more of the histamine from the rest of a meal through. The evidence is thin, though. The 2021 review that discussed it found only old laboratory and animal studies, the most recent from 1985, and that one showed an effect in rats when putrescine was present at four to five times the level of histamine.

The published diets reflect that uncertainty. Four of the ten low-histamine diets in the 2021 review exclude banana, and a 2024 clinical review lists bananas among the fruits to avoid. The other six diets in the review do not exclude them.

We rate banana 1, "mostly low", and mark it disputed: no histamine in any measured sample, a real but unproven concern from putrescine, and lists that split. In practice that means a banana on its own is unlikely to be a large histamine load. If you do react to bananas, the putrescine question is the likely reason and is worth raising with your dietitian. Cherries, which had under a tenth of the putrescine in the same study, are an option if you want a fruit with fewer open questions.

Questions about banana and histamine

Are ripe bananas higher in histamine than green ones?

We found no study that measured this. The bananas tested were ordinary shop-bought fruit, and none had detectable histamine.

Evidence behind this page

  • Bananas sold in Spain had no detectable histamine and an average of 37.94 mg/kg putrescine (8 samples). 1
  • The idea that putrescine blocks histamine breakdown by DAO rests on old in-vitro and animal studies, the latest from 1985. 2
  • Four of ten published low-histamine diets exclude banana. 2
