Sensitivity notes
Why fodmaps food checker matters
FODMAPs are fermentable carbohydrates that can cause digestive distress in sensitive individuals. They include fructose, lactose, fructans, galactans, and polyols. These sugars are poorly absorbed in the small intestine and ferment in the colon, potentially causing bloating, gas, and discomfort.
- Start with a 2-6 week elimination phase, removing all high-FODMAP foods
- Keep a detailed food and symptom diary to track your reactions
- Reintroduce one FODMAP group at a time to identify your specific triggers
- Remember that threshold varies - you may tolerate small amounts
- Work with a dietitian trained in the low-FODMAP diet for best results

What to know about calcium carbonate
Calcium carbonate (E170) is purified limestone, and it is the most chemically boring thing on most ingredient lists. It grades A on every intolerance criterion this app tracks: no histamine, no salicylate, no FODMAP, no gluten, no dairy protein, no sulfite, no glutamate. If it is on a label near a reaction, it is almost certainly not the culprit. Where it does matter is dose and timing, because the same compound fortifying your oat milk is also the chalky antacid tablet, and at that scale it changes stomach acid, bowel habit and how well other things are absorbed.
Watch for
- At supplement or antacid doses it is a well known cause of constipation, and it fizzes with stomach acid to release carbon dioxide, so belching and upper-gut fullness after a big dose are the compound doing exactly what it does
- It needs stomach acid to dissolve, which is why it should be taken with food and why it works poorly for anyone on a proton pump inhibitor.Calcium citrate does not have that requirement
- It binds other things in the gut.Iron and zinc absorption drop when taken alongside it, and it interferes with levothyroxine, tetracycline and quinolone antibiotics, which is a spacing problem rather than a sensitivity one
- Graded E for AIP purely because elimination protocols exclude added mineral compounds on principle, not because of any measured trigger

FODMAPs Guide
Everything you need to know about fodmaps sensitivity and smart food choices.
FODMAPs are fermentable carbohydrates that can cause digestive distress in sensitive individuals. They include fructose, lactose, fructans, galactans, and polyols. These sugars are poorly absorbed in the small intestine and ferment in the colon, potentially causing bloating, gas, and discomfort.
Sensitivity varies widely. What triggers one person may be fine for another. Track your reactions to find your personal threshold.
