Sensitivity notes
Why lectin food checker matters
Lectins are proteins found in many plant foods, especially legumes and grains. Some people follow low-lectin diets believing they reduce inflammation and digestive issues, though properly cooked foods have reduced lectin content.
- Proper cooking destroys most lectins - never eat raw beans
- Pressure cooking is highly effective at reducing lectins
- Peeling and deseeding reduces lectin content
- Fermentation can reduce lectins in some foods
- Sprouting may increase or decrease lectins depending on the food

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
