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 citric acid
The single most useful fact about citric acid is that it does not come from citrus. Essentially all of the commercial supply is grown, not squeezed: a black mould called Aspergillus niger is fermented on a sugar feedstock, usually corn-derived glucose syrup and sometimes molasses or cassava, and the acid is precipitated out and purified. That matters in two directions. Anyone avoiding corn cannot treat citric acid as automatically corn-free, and the people who report reacting to manufactured citric acid while eating lemons and limes without trouble at least have a plausible reason to tell the two apart. On the chemistry we grade, citric acid is clean: A on histamine, A on histamine liberation, A on tyramine, sulfites, gluten, dairy protein, nickel, free glutamate and nightshade. It is also in almost every sour sweet and soft drink there is, which makes it one of the most heavily confounded suspects a food journal can throw up.
Watch for
- Not a citrus product.Industrial citric acid is a fermentation product of Aspergillus niger grown on a sugar substrate, most often corn glucose syrup, so it is a hidden corn exposure for anyone eliminating corn and a mould-derived ingredient for anyone tracking that
- It appears as E330 on European labels, and its salts (sodium citrate, potassium citrate, calcium citrate) are made from the same acid by the same route.If you are avoiding it for feedstock reasons, the citrates count too
- The products that carry the most of it are sour sweets, gummies, energy and soft drinks, flavoured water and sports drinks, which also carry colours, intense sweeteners, preservatives and caffeine.A reaction logged against citric acid is very often a reaction to the product it came in
- There is a direct contact side that has nothing to do with intolerance: strongly acidic sweets and drinks erode tooth enamel and can leave the lips, tongue and mouth raw or ulcerated.That is chemical irritation at the surface, not a systemic response
- Published reports of intolerance to manufactured citric acid specifically exist, but they are a handful of case descriptions rather than an established condition.Treat it as a hypothesis to test in your own log, not a diagnosis

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.
