Food & symptoms · Food Intolerance
A food intolerance tracker built for delayed, dose-dependent reactions
An allergy is an immune response, and it's usually fast and obvious. An intolerance is a digestive or metabolic one: slower, dose-dependent and cumulative, which is precisely the shape of problem human pattern-matching is worst at. You ate the thing on Tuesday and felt wrong on Thursday, having eaten roughly ninety other things in between.
For anyone chasing a delayed, dose-dependent reaction that nobody can pin down.
Why this is hard to keep track of
- Reactions lag by hours to days, so the obvious suspect is usually the wrong one
- It's dose-dependent, so eating it once without incident proves nothing
- Load accumulates across a day, and no diary captures a total
- Cutting foods on suspicion narrows the diet without ever producing an answer
Worth recording
- What you ate and roughly how much of it
- The symptom, how long after, and how bad
- Total load across the day rather than a single meal
- The non-food variables that move the same symptoms
Cadence
A sentence after meals, symptoms whenever they show up
In practice
Say it once, in whatever words you have
The moments most worth recording are the ones where filling in a form is the least realistic thing in the world. A sentence, typed or dictated afterwards, is a much lower bar — and it carries the context a checkbox would have lost.

log_food(items: ["cheese sandwich"], reaction: false)log_food(items: ["latte", "yoghurt"], reaction: true, date: "yesterday")estimate_load(nutrient: "lactose", window: "day")find_pattern(metric: "symptoms", group_by: "lactose_dose")
Every figure here was counted from entries you made. The model picked which tools to call — it doesn't interpret, diagnose, or decide what anything means about anyone.
And then ask
The question the log can answer
Months of entries hold real answers to the questions you've been guessing at, and reading them properly has always meant a spreadsheet and a free evening — which is not a thing anyone in this situation has.
Ask in plain language. The answers come back with the numbers behind them, including when those numbers are too thin to mean anything yet — which is the more useful answer more often than people expect.
Called 3 tools
get_history(topic: "food-intolerance", window: "6m")find_pattern(group_by: "antecedent")compare_periods(metric: "events")
Counts and averages over your own entries, nothing more. Where the data is confounded or too thin, the answer says so instead of rounding it into a conclusion.
The reason most people start
Something to actually bring to the appointment
You get fifteen minutes, once, after waiting months for it. The questions are specific and the honest answers are all some version of "I don't know, it's hard to say".
What this gives you: Dated food-and-symptom pairs with timings, which is something a GP or dietitian can actually act on.
- Export the date range you were asked about, as a file you can print
- Counts and timings rather than an impression of the worst week
- Your own notes kept alongside the numbers, in your words
- Nothing shared anywhere unless you choose to share it
What it won't do
- Diagnose anything, or suggest that it could
- Score a person, or rank them against anyone else
- Set a target for fewer events, or a streak of good days
- Recommend a treatment, a therapy, a diet or a medication change
- Share your record with a school, a clinician or anyone else on its own
It's a notebook that can do arithmetic and answer questions about itself. Deciding what any of it means is a job for you and the people advising you.
