Histamine Checker is a small, independent project. Its only job is to give you a fast, private, no-signup estimate of how histamine-heavy a meal looks — using the food tolerance scale that low-histamine diets are actually built on.
Most people who suspect histamine issues hit a wall of contradictory food lists. We wanted one simple tool: tick what you ate, see a relative load, and learn why freshness matters. No account, no tracking, no upsell.
Our food scores follow the SIGHI Food Compatibility List (Swiss Interest Group Histamine Intolerance), the most widely referenced low-histamine reference. Scores are tolerance ratings (0–3), not measured milligrams — we say so plainly in the tool. This tool uses a simplified subset of the SIGHI list; for precise ratings always cross-check the official SIGHI publication. Health context on this site is drawn from publicly available clinical and dietetic summaries (e.g. Mayo Clinic–style overviews, low-histamine diet guides).
This is an independent educational project maintained by volunteers interested in making low-histamine eating easier to understand. We are not a clinic and do not provide personal medical recommendations.
We would rather tell you a score is a tolerance rating than pretend it is a lab measurement we do not have. Every page states its sources and limits. If you spot an error, our Contact page is open.
