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?

Your starting hint

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.

Why five questions

The five questions are not a test and there are no trick answers. They map onto the patterns clinicians and dietitians actually ask about: reaction frequency, sensitivity to aged or restaurant food, response to fermented foods, relief on a plain fresh diet, and medicines or gut issues that can slow histamine breakdown. Together they give a sensible place to start before you touch the slider.

What to do with your hint

Your hint sets the calculator's starting sensitivity and freshness, then opens the tool. Treat it as a guess, not a verdict. Cook a few fresh meals, watch how you feel, and nudge the sensitivity up or down until the verdict matches your real life. The whole point is to learn your own line, not ours.

When to see a professional

If symptoms are frequent, severe, or affect more than digestion — think flushing, wheezing, or swelling — do not rely on a self-check. A doctor can rule out other causes and a dietitian can build a structured elimination and reintroduction plan far safer than trial and error.

How your answers are stored

Your answers are written only to your browser's local storage so the calculator can pre-set itself. They are never uploaded, never emailed, and vanish when you clear your browser data. This check cannot identify you.

A note on accuracy

Five questions cannot capture a full medical history. They are a starting hint, useful because most people have no idea where they sit on the scale. Use the hint, test it against real meals for a week, and adjust. If patterns are strong or symptoms are severe, bring your notes to a professional rather than trusting a quiz.
