Sensitivity notes
Why fructans food checker matters
Fructans are chains of fructose molecules found in wheat, onions, garlic, and many other foods. They're a type of FODMAP that can cause digestive symptoms in sensitive individuals because they're not well absorbed in the small intestine.
- Garlic-infused oil is low-FODMAP since fructans don't dissolve in oil
- Green parts of leeks and scallions are lower in fructans
- Sourdough bread may be better tolerated than regular wheat bread
- Spelt and ancient grains still contain fructans despite marketing claims
- Portion size matters - small amounts may be tolerable

What to know about ammonium sulfate
Ammonium sulfate (E517) shows up on commercial bread labels as a yeast nutrient and dough conditioner. It feeds the yeast nitrogen so a fast industrial dough ferments predictably, buffers the pH as that fermentation runs, and firms up the gluten network so the dough survives machine handling. It grades A on every sensitivity criterion tracked here, including sulfite, which matters because the name misleads a lot of people: sulfate is not sulfite and it will not set off sulfite-sensitive asthma.
Watch for
- Not a sulfite.Sulfate is the fully oxidised form and cannot release sulfur dioxide, so it does not carry the asthma and wheeze risk that E220 to E228 sulfites do. It is graded A here for exactly that reason
- Clean across histamine, salicylate, oxalate, FODMAPs, gluten, dairy protein, glutamate and nickel.Whatever a supermarket loaf is doing to you, this is not the ingredient doing it
- Graded C for anti-inflammatory, AIP, DASH and Mediterranean.That is a signal about the product, not the salt: E517 is a marker of high-speed industrial baking, and the fast-fermented white bread it enables is the thing worth logging
- Much of it never reaches your plate.It is added as yeast food, so the yeast consumes a good share of the nitrogen during proofing
