Sensitivity notes
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 flageolet beans
Flageolet beans are the pale green French beans picked before they mature, then dried away from the light so they keep their colour, and served classically alongside a leg of lamb. That immature harvest is what gives them their thin skin and creamy bite, but it does not make them a gentle legume. Flageolets carry the top rating for galacto-oligosaccharides, the worst possible rating for SIBO among common beans, high lectins and high nickel, with moderate oxalate on the side. They are clean on gluten, lactose, salicylates and nightshades, so if flageolets sit badly the cause is fermentation and mineral load rather than food chemistry.
Watch for
- Top rating for GOS combined with the worst SIBO rating of the everyday beans, which makes flageolets a poor choice while bacterial overgrowth is being treated
- Harvested young means a thin skin and a shorter cook, and that is exactly why they get underboiled; lectins rate high and only a genuine rolling boil breaks them down
- Flageolets are plated as the side dish to lamb rather than scattered through a stew, so the portion is large by design, and portion is what decides whether a high-GOS food is survivable
- Moderate in oxalate and high in nickel, two loads that accumulate quietly across a day instead of announcing themselves as an immediate gut reaction
- Tinned flageolets sit in liquid that has drawn water-soluble FODMAPs out of the beans, so draining and rinsing the tin is worth doing even though the bean looks delicate enough not to need it
