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 sweet potato
Despite the name, sweet potato is not a nightshade. It belongs to the morning glory family (Ipomoea batatas), while the white potato is the actual nightshade (Solanum tuberosum), so people avoiding nightshades can usually eat sweet potato freely. Its real trigger is oxalate: sweet potato is high in oxalate, with roughly 97 mg in a medium one, which matters for anyone prone to calcium-oxalate kidney stones.
Watch for
- High in oxalate, around 97 mg per medium sweet potato, a meaningful amount for anyone managing calcium-oxalate kidney stones or on a low-oxalate diet
- Not a nightshade: it is in the morning glory family, unlike the white potato, so nightshade-sensitive people generally tolerate it
- Moderate salicylate and moderate polyols, so a large portion can also add up for sensitive guts
