Potassium sulfite
Potassium sulfite is high in Histamine. If you're sensitive to any of these, check it against your profile before eating.
Intolerances
- Histamine (+liberators / DAO inhibitors)High
Sulfites (E220-228) are the best-evidenced additive on this list. They do not contain histamine: they inhibit DAO, the enzyme that clears it, so they lower your headroom for everything else in the meal. This is also why wine is worse than its histamine content alone suggests — the sulfites and the alcohol both block the same clearance. Sources: Maintz & Novak, Am J Clin Nutr 2007 (histamine intolerance review); Comas-Basté et al., Biomolecules 2020; EFSA re-evaluation of sulfites, 2016. Note EU law already requires 'contains sulphites' above 10 mg/kg, so the label will tell you.
