Getting started
What is Aistamine
Aistamine is a digital diary for people living with histamine intolerance. It lets you log meals, track symptoms and visualise correlations over time.

The diary
The diary is the core of Aistamine. By logging your meals every day, the system can calculate correlations with your symptoms.

Breakfast

How to add a food item
Tap the + button next to the relevant meal. A panel opens with three modes: database search, barcode scan, AI classification.
Database search
Type the first letters of the food. The system searches the database with A-E histamine classification already assigned.
Barcode scan
Point the camera at a packaged product barcode. The system automatically retrieves the name, ingredients and nutritional values.
AI classification
Type a dish name and the AI generates the ingredient list with the corresponding classification.
Editing or deleting an entry
Tap a diary entry to open the detail view. From there you can edit the quantity, add notes or delete the entry.
The A-E scale
Each food is rated from A (safe) to E (avoid). The rating is based on histamine content and the food's ability to trigger histamine release.
A
Safe
Low histamine
B
Tolerated
Moderate histamine
C
Moderate
Medium-high content
D
Limit
High histamine
E
Avoid
Very high histamine
Symptoms
Logging symptoms is essential for accurate correlations. Record the symptom as soon as you feel it, not at the end of the day.

How to log a symptom
In the diary, on the right column, tap Add next to Symptoms. Select the symptom type and rate its intensity from 1 to 10.
Why log symptom-free days too
Symptom-free days are valuable data. They allow the system to calculate your personal baseline and distinguish safe foods from suspicious ones.
Histamine delay
Histamine can act with a delay of 30 minutes up to 48 hours. This is why the system analyses the two days before each symptom episode.
Statistics
Statistics improve with time and the repetition of events. After a few weeks the first patterns start to emerge, after a couple of months the results become more accurate, and after a year of diary entries the correlations are truly precise. The more data you have, the more the system can narrow down and identify your real triggers.
How they improve over time
The first weeks show initial trends. With a few months of data the patterns consolidate. With a year or more of diary the correlations are precise because the system has seen the same event repeat in different contexts.

AC
Histamine accumulation over time
The line rises when you eat risky foods (D/E) and falls on rest days. When it crosses the red threshold, symptoms appear.
SP
Foods to watch out for
We compare how often each B/C/D/E food appears on symptom days vs ok days. The longer the bar, the more suspect.

Daily histamine score
Each day the score is the average histamine level of the foods you consumed, converted to numbers: A=0, B=1, C=2, D=3, E=4. The lower the score, the safer your diet was.

Which day do you feel worst?
Average symptom intensity by day of the week. If one day is always critical, check what you eat the day before — histamine acts with a 12–24h delay.
