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.
If a tool can't say what it doesn't know, it shouldn't pretend to.
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.
Most people do not need a diagnosis to start paying attention — they need a mirror. The calculator turns a vague "I think leftovers upset me" into a visible pattern: which foods sit in the red, which swaps bring the load down, and how much freshness alone moves the needle. Over a week or two you build your own private map of triggers without logging into anything or handing over an email address.
We promise three things. Honesty about limits: every score is labelled a tolerance rating, never a measurement. No lock-in: there is no account to create and no data to lose if you leave. Open correction: the food list is a simplified subset of SIGHI, and if we have a rating wrong, our Contact page is open for fixes. A tool you cannot correct is a tool you should not trust.
This project runs on a static host with no database and no paid plan, which is why it can stay free and ad-free for now. If we ever add privacy-respecting analytics or advertising to cover costs, that will be disclosed here and in our privacy page first — never slipped in quietly.
We are not a clinic, not a dietitian, and not a substitute for medical care. If a food scores "safe" on our scale but your body disagrees, your body wins. The tool is a map, not the territory — useful for noticing patterns, useless as a verdict.
