Why polyols food checker matters
Polyols (sugar alcohols) are found naturally in some fruits and vegetables, and are used as artificial sweeteners. They're poorly absorbed and can cause digestive symptoms, especially in IBS sufferers.
- Avoid sugar-free products with sorbitol, mannitol, xylitol, maltitol
- Stone fruits are naturally high in polyols
- Cooking doesn't reduce polyol content
- Avocado portion size matters - small amounts may be fine
- Cauliflower and mushrooms are common triggers

What to know about banana
Banana is the food where ripeness changes the answer. A firm, barely-yellow banana is mostly resistant starch and behaves as a low FODMAP fruit, while the same banana spotted and soft has converted much of that starch into free sugars and short-chain fructans, which is why it moves into moderate territory. That single fact resolves most of the arguments about whether banana is low FODMAP. The second story is amines. Banana appears on nearly every migraine and MAOI handout, and our grades support a moderate reading rather than a dramatic one: moderate tyramine and moderate histamine liberation, but clean on histamine itself. It is also moderate on nickel and lectins, which matters if you are on a low-nickel protocol. It is clean on gluten, lactose, salicylates, glutamates, sulfites and nightshade.
Watch for
- Ripeness flips the FODMAP verdict.Green and firm means resistant starch and a mild grade, while spotted and soft means more free sugar and fructans, so the tolerable portion shrinks as the fruit ages
- Moderate on fructans and sorbitol but clean on excess fructose, so banana is not a fructose problem and pairing it with glucose will not help the way it does with honey or mango
- Moderate tyramine, which is why banana is a fixture on MAOI and migraine lists.The tyramine is concentrated in the peel and rises as the skin blackens, so over-ripe fruit is the version worth watching
- Moderate histamine liberator while grading clean for histamine content, so it can provoke flushing or headache in a sensitive person without ever being a high-histamine food
- Moderate nickel and moderate lectin, both relevant on low-nickel diets for systemic nickel allergy and on lectin-restricted plans
- Moderate for SIBO, and here green beats ripe in reverse: the resistant starch that makes an unripe banana low FODMAP is precisely what low-fermentation SIBO protocols limit
