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 white miso
White miso, shiro, is the mildest member of the family: a high proportion of rice koji, comparatively little soybean, and a ferment measured in weeks rather than the year or more a dark miso gets. The grades bear out what the pale colour and sweet flavour already suggest. Set against our general miso paste entry, white miso comes out lower on histamine, substantially lower on tyramine, lower on free glutamate, lower on the soy FODMAP and clean rather than moderate on sulfites. Less time and less soy means fewer biogenic amines and less protein broken down into free glutamate. It is also typically the lowest-salt miso, around half the sodium of a dark red one. None of that makes it a blank food. It is still fermented soy, so histamine and galacto-oligosaccharides both land at moderate, and it carries a moderate gluten flag because koji is not always cultured on rice.
Watch for
- Genuinely milder than dark miso on every amine column: our general miso entry grades high for histamine and high for tyramine, while white miso grades moderate and low-moderate respectively, and free glutamate drops from high to low-moderate with it
- Still moderate for histamine, because a short ferment is a ferment.If your histamine threshold is low, moderate stacks with the rest of the meal
- Moderate galacto-oligosaccharides, the soybean FODMAP.A spoonful stirred into a bowl of soup is a small dose. A dressing or marinade built around miso is a much larger one
- Moderate gluten flag.Rice-koji shiro miso is normally free of wheat and barley, but barley koji and wheat-containing misos are both traditional, so the label decides rather than the colour
- Clean on sulfites, nitrites, lactose and dairy protein, so the salty savoury depth arrives without any of those
