Why lectin food checker matters
Lectins are proteins found in many plant foods, especially legumes and grains. Some people follow low-lectin diets believing they reduce inflammation and digestive issues, though properly cooked foods have reduced lectin content.
- Proper cooking destroys most lectins - never eat raw beans
- Pressure cooking is highly effective at reducing lectins
- Peeling and deseeding reduces lectin content
- Fermentation can reduce lectins in some foods
- Sprouting may increase or decrease lectins depending on the food

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
