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 sourdough bread

Genuine long-fermented sourdough is the rare bread that is easier on a sensitive gut. The slow ferment lets bacteria break down 70 to 90 percent of the wheat fructans, which is why Monash rates real sourdough as lower FODMAP than standard wheat bread. But lower FODMAP is not the whole story: sourdough is still wheat, so it contains gluten, and the fermentation actually raises its tyramine, a trigger for migraine and for anyone on an MAOI.

Watch for

  • Still made from wheat, so it contains gluten and is off limits for celiac disease and gluten sensitivity, low FODMAP or not
  • The long fermentation raises tyramine, which can trigger migraine or a dangerous spike for people taking MAOI medication
  • Only a true 16 to 24 hour ferment lowers the fructans: supermarket loaves flavored with sourdough but proofed quickly stay high FODMAP
