Sensitivity notes
Why lactose food checker matters
Lactose is the natural sugar in milk and dairy products. People with lactose intolerance lack sufficient lactase enzyme to digest it, leading to bloating, gas, and digestive discomfort after consuming dairy.
- Try lactose-free dairy products - they're real dairy with lactase added
- Hard aged cheeses are naturally lower in lactose
- Lactase enzyme supplements can help when eating dairy
- Yogurt and kefir may be better tolerated due to probiotics
- Your tolerance level is personal - some can handle small amounts

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
