Find the Food Behind Your Symptom Pattern

A symptom that comes and goes has a trigger hiding in the week's food — but a diary read as prose hides it. This reads each day as food items plus a symptom note, counts which foods keep showing up on the bad days, and ranks them as candidates. Local only; your diary never leaves the tab.

The workflow

  1. Log each day on one line

    Format it as 'foods — symptom', like 'oatmeal, coffee, sandwich — headache by 4pm'. One line per day, every day, including the good ones — the contrast is what makes the pattern show.

  2. Include the symptom-free days

    A trigger only stands out against days you felt fine. Days with no symptom get the same food list and no symptom note; the tally needs both columns.

  3. Read the candidates as hypotheses, not verdicts

    A food that co-occurs with the symptom three times is a candidate to test, not a diagnosis. The board ranks them so you can try one change at a time — the only way a pattern test stays readable.

  4. Bring the ranked list to the appointment

    The questions the board prints are the ones a clinician can actually use: which foods, how often, how long after. That's the diary doing its job.

Worked example

Sample: 4 days, 3 with headache
  Days             4
  Symptom days     3 (headache)
  Candidates       coffee (3/3), aged cheese (2/3), bread (1/3)
  Questions        4 doctor-ready questions
  Uploaded         nothing — tallied in the tab

Numbers above are sample data produced by the tool's own pre-loaded example, run in the browser — not averages or measured benchmarks.

What breaks this

Logging only the bad days gives the tally nothing to contrast against — the good days are the control. One-word symptom notes like 'bad' hide the pattern; 'bloated by 8pm' is readable. Dropping four foods at once after a guess makes the next week's diary unreadable — change one, keep logging. This board finds candidates, it does not diagnose.

What this is not. This counts co-occurrence in the diary you kept — it does not diagnose a food allergy, intolerance, or any condition, and it cannot rule anything out. A pattern of severe or concerning symptoms belongs with a clinician, not a tally.
