Safe Food Guidelines

Reading a condition’s own guidance, and what to do when two conditions disagree

5 min readUpdated Sep 3, 2026

General guidance for eating with a health condition, and how to get ClapDiet to

do the specific part for you.

Start with the condition, not with a list

Every condition in the catalog carries its own guidance, written for it rather

than assembled from a generic template. Open it — Health Conditions on the

web, the Conditions card on the phone's home screen — and you get:

  • the nutrients to emphasize, to limit, and to get the amount of right
  • the eating patterns it turns on, as sentences
  • foods to prefer and foods to avoid, each with example foods from the database
  • the lab tests worth watching, and what each is being watched for
  • the diet modes it works with, and the ones it rules out
  • That is the specific answer for your condition. What follows is the part that is

    the same whatever you have.

    Three habits that do most of the work

    Know which nutrient is yours

    Almost every dietary restriction reduces to a small number of nutrients. Sodium

    for hypertension. Potassium and phosphate for kidney disease. Purines for gout.

    Oxalate for calcium-oxalate stones. Find yours on the condition's own page and

    learn to read for it.

    Read the label, not the front of the pack

    For packaged food, the serving size on the label is the number everything else

    depends on. ClapDiet stores nutrients per 100 g, so two products are directly

    comparable in the app even when their packs are not.

    Ask a professional the questions the app cannot answer

    ClapDiet does not know your stage, your last set of bloods, or what your

    nephrologist said last month. Your doctor, dietitian and pharmacist do. The

    clinician report exists to make that conversation shorter, not to replace it.

    Where the app does the work for you

    Food ratings

    Twenty-one conditions carry a per-condition rating on every food. Look at a food's

    page and you see how it rates for yours, on the one-to-five scale where one is

    avoid and three is a genuine neutral.

    Diet modes

    Six modes plus standard. A condition rules some of them out; the condition's

    Modes tab says which, and why it matters is on the mode's own page.

    Medication cautions

    Add your medicines and the interaction layer checks foods against them. See

    Medication Tracking.

    Logging

    Tracking what you eat is what turns any of this from advice into a picture of

    what you actually do. See

    Daily Food Logging.

    When two conditions disagree

    They will. Kidney disease wants potassium down; hypertension wants it up.

    Osteoporosis wants calcium; kidney stones want it timed with meals rather than

    avoided.

    ClapDiet does not silently pick a winner. Add both and you get both sets of

    guidance, both sets of ratings, and both sets of cautions, each labelled with the

    condition it came from. The judgement about which takes priority is a clinical

    one and it stays with your clinician — which is exactly the conversation

    Clinician Report is built for. It collects your conditions, medications,

    allergies, current interactions and recent labs onto one printable page.

    A note on eliminating things

    Several of the core-therapy conditions — celiac disease, food allergy,

    eosinophilic esophagitis, PKU, galactosemia, hereditary fructose intolerance —

    work by removing something completely. Removal is only half of it. Every one of

    those conditions carries an eating pattern about replacing what you removed, for

    the reason that a diet built by subtraction runs short of something eventually.

    Read that pattern on the condition's page; it is there for you, not as

    boilerplate.


    Remember: This is general guidance. Your individual needs may differ. Always

    follow personalised medical advice.
