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 peanut oil
Peanut oil is the textbook case of an allergen that survives or disappears depending on how the oil was made. Highly refined peanut oil, the kind used in commercial fryers and sold as plain cooking oil, has been de-gummed, neutralised, bleached and deodorised, which strips out the peanut protein that actually causes allergic reactions. That is why US law exempts highly refined peanut oil from allergen labelling and why many peanut-allergic people eat fries cooked in it without incident. Cold-pressed, expeller-pressed and aromatic gourmet peanut oil is a different product: it keeps residual peanut protein and is not considered safe. On the food-chemistry triggers Triggerbites tracks, peanut oil is clean, with A grades on histamine, histamine liberation, tyramine, nickel, sulfites, glutamates and gluten. Its high grades are the legume-origin lectin marker and a pro-inflammatory rating driven by its heavy omega-6 load.
Watch for
- Refining status is the whole story: highly refined peanut oil is protein-stripped and allergen-exempt on US labels, while cold-pressed, expeller-pressed and gourmet peanut oil retains peanut protein and should be avoided with a peanut allergy
- Because the refined form is exempt from labelling, a product or restaurant is under no obligation to declare it, so "no peanut on the label" is not the same as "no peanut oil in the fryer"
- Graded high on lectins, reflecting its legume origin.The plant protein fraction that carries lectins is exactly what full refining removes, so unrefined bottles are the ones to question
- Rated pro-inflammatory: peanut oil is roughly a third linoleic acid, so it pushes omega-6 intake up if it is your default cooking fat
- Clean on histamine, histamine liberation, tyramine, nickel, sulfites and gluten, and only borderline on FODMAPs, since FODMAPs are water soluble and do not carry into pressed fat
