How reactive are you, really?

A quick, qualitative self-check to help you pick a starting sensitivity on the calculator. This is for self-awareness only — it cannot diagnose histamine intolerance or any medical condition.

Five quick questions

Answer as honestly as you can. There are no right or wrong answers — only patterns that help you start somewhere sensible.

After eating, how often do you get flushing, hives, itching, or a stuffy nose?

Do leftovers, restaurant meals, or packaged foods trigger you more than fresh home-cooked meals?

Do fermented foods (yogurt, sauerkraut, wine, aged cheese) bring on symptoms?

When you eat a fresh, plain diet for a few days, do your symptoms ease?

Do you take medicines (some NSAIDs, certain antibiotics) or have gut issues that can slow histamine breakdown?

How to read this. The calculator works best when you know your own sensitivity. Most people don't at first, so this check gives you a sensible place to start. Adjust the slider on the calculator up or down as you learn how your body actually responds.

This self-check is not a medical test or diagnosis. It cannot tell you whether you have histamine intolerance, a DAO deficiency, or any other condition. It only reflects how you answered five questions. For real guidance, speak with a doctor or a registered dietitian.
