Sensitivity notes
Why oxalates food checker matters
Oxalates are compounds found in many plant foods that can bind with calcium to form crystals. High oxalate intake may contribute to kidney stones in susceptible individuals and can cause other symptoms in those with oxalate sensitivity.
- Stay well-hydrated to help prevent oxalate crystal formation
- Pair high-oxalate foods with calcium-rich foods to bind oxalates
- Cooking and boiling can reduce oxalate content in some foods
- Spread oxalate intake throughout the day rather than one large dose
- Consider probiotics - some gut bacteria break down oxalates

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
