How to find food triggers without cutting everything out

The standard advice when food might be the problem is to cut everything: dairy, gluten, sugar, caffeine, alcohol, half the vegetable aisle. Most people last nine days. Then life happens, everything comes back at once, and you've learned exactly nothing except that restriction is miserable.

Here's the thing nobody says: you don't find food triggers by removing food. You find them by removing GUESSING. Those are different projects.

Why all-at-once elimination usually fails

Cut fifteen things and feel better, and you still don't know which one mattered. Worse, feeling better for two weeks proves less than you'd hope, because symptoms drift on their own. Without a record, you're comparing a fuzzy memory of last month to a fuzzy sense of this week. That's not an experiment. That's a vibe.

One suspect at a time

The method that ended a decade-long mystery in my family fits on an index card:

Eat simple and repeatable during the week. Meals you already trust, boring on purpose, because boring is what makes a signal readable.

Pick ONE suspect, and test it on the weekend. One meal built around the thing you're questioning. This is a test, not a cheat.

Write three lines the next morning. Sleep, stomach, energy, each out of ten. Dated. Ten seconds.

Repeat for three weekends. Then read the mornings side by side.

Day to day, you can't feel a pattern. But three test mornings lined up on paper will either show you something ("rough morning after the bread, three for three") or clear the suspect, and a cleared suspect is real progress. It's one less thing to fear, and most people never get even that.

The rules that keep it honest

Change one thing at a time, or the answer belongs to nobody. Give each suspect its own weeks. And write things down even when nothing happened, because "nothing happened" is data too. Reacting to a food some days and not others usually means the dose, the combination, or the week matters, which is exactly what a written record can untangle and memory cannot.

What this is and isn't

A pattern on paper is a lead, not a diagnosis. Some reactions (swelling, trouble breathing, hives) are emergencies, not experiments, and belong with a doctor immediately. And if a trigger pattern does show up, a clinician should hear about it, because "reliably worse after X, documented for three weeks" is a sentence doctors can actually work with.

You can run all of this with a notebook. If you'd rather have something that keeps the record and does the honest math with you, that's exactly what we built Cadence to do. But start this weekend either way. One suspect. Three lines a morning. It beats a year of guessing.
