NutriSpy

A histamine food diary that shows what your worse days follow

Every meal with an estimated histamine value.

Most frequent symptoms in the NutriSpy statistics

Why a diary helps when you suspect histamine intolerance

The usual suspects are easy to name – aged cheese, red wine, sauerkraut, salami – and hard to confirm. Cutting out everything at once tells you nothing; cutting out the wrong thing costs you a food for no reason.

A histamine food diary asks your own days instead: which meals did the worse ones follow, and how much time sat in between?

Frequently asked questions

Which foods are high in histamine?

Mostly long-aged and fermented foods: aged cheese, red wine, sauerkraut, cured sausage such as salami. In fish, histamine rises with storage time. How you feel after them differs from person to person – your diary shows how your own days line up.

How accurate is the histamine value?

It is an estimate. NutriSpy breaks every meal into ingredients and estimates its histamine from them. Histamine varies with ripeness, storage and preparation more than most nutrients do. As a guide value it is enough to compare meals and to test a suspicion against your own days.

Which symptoms can I log?

Headache, flushing, itching, a racing heart, bloating, diarrhoea – named as a symptom, with the time it happened. The time is what later shows the gap to the meal. Sleep and workouts come in from Apple Health or Health Connect, because not every bad day is about food.

How soon do I see results?

After five logged days, NutriSpy shows from your own data which meals and habits go with your worse days. The histamine and FODMAP values of your meals are part of that. Every pattern comes with an estimate of how solid it is – so you can stop avoiding a food that never went with a worse day. Missing days are treated as missing, not guessed.

Does the diary replace a diagnosis?

No. A diary shows what goes together in your own data – it does not diagnose. NutriSpy never names a condition and never suggests a medication. What lies behind your symptoms is for your doctor to work out; the diary is the basis for that conversation.

What does NutriSpy cost?

Your diary is free. AI-powered logging is part of Premium, with a few free entries each month. The insights, sync back to Apple Health or Health Connect and the export are part of Premium, by subscription. Current prices are shown in the app.
