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

Serving size, prep, and portion notes for parsnip root
Parsnip root is rated clean on almost every food chemistry trigger we track: no gluten, no lactose or dairy protein, nothing on histamine or histamine liberation, no nightshade, no sulfites, no free glutamate, and low FODMAP at a normal roasting portion. What it carries is a moderate salicylate and oxalate rating rather than a high one, plus the odd distinction of being one of the few vegetables that can burn your skin before it ever reaches the plate. Parsnip foliage and sap are rich in furanocoumarins, which react with sunlight, so the classic parsnip complaint is a streaky rash on the forearms of whoever pulled or peeled a pile of them, not indigestion after dinner.
Watch for
Sap plus sunlight causes phytophotodermatitis: a burn-like, sometimes blistering rash in streaks where the leaves or cut sap touched skin, appearing a day or two later and often leaving brown marks for weeks. Gloves and sleeves when harvesting or peeling a large batch prevent it. Eating cooked parsnip does not do this / Furanocoumarin levels climb in roots that are bruised, blackened, mouldy or very long stored, so cut damaged parts away generously instead of trimming lightly / Salicylates rated moderate: nowhere near the level of berries or dried herbs, but during the strict phase of a salicylate elimination it still counts as a middle-of-the-road food rather than a free one / Oxalate rated moderate here, and published oxalate figures for parsnip vary widely between tables. If you are managing kidney stones, treat it as a food to test and log rather than one to assume either way / Parsnip sits in the carrot and celery family, so people with birch pollen cross-reactivity can get an itchy or tingling mouth from raw parsnip. Cooking usually breaks down the proteins responsible
