Caffeine
Caffeine contains moderate levels of Histamine. If you're sensitive to any of these, check it against your profile before eating.
Intolerances
- Histamine (+liberators / DAO inhibitors)Moderate
Caffeine holds no histamine; it is flagged because it is reported to slow DAO, so it narrows your headroom rather than adding to the load. The evidence is thinner than for alcohol or sulfites — worth testing on yourself rather than cutting on principle. Sources: Maintz & Novak, Am J Clin Nutr 2007; SIGHI food list.
