Is Knorr Chicken Stock Cubes low FODMAP?

Knorr Chicken Stock Cubes are a moderate risk: onion powder and celery seeds are both on the UK label, though they sit near the end of the list and end up heavily diluted in the finished dish. The full ingredient list runs salt, starch, vegetable fats (palm, shea, sal), yeast extract, sugar, chicken fat (3%), flavourings, chicken (1%), spices (turmeric, pepper, celery seeds), lemon juice powder, onion powder, parsley, caramel syrup and maltodextrin. So the cube is mostly salt, starch and fat — no wheat, no garlic, and the yeast extract that gives it savour is low FODMAP at these quantities. The flags are the concentrated onion powder, the celery seed (small, but one of the exact ingredients stock-cube hunters try to screen out) and the unspecified 'flavourings', whose composition you can't check. Diluted at one cube per 450ml, the onion dose in a single bowl is genuinely small, which is why many sensitive cooks get away with it in gravies and one-pot dishes. During a strict onion-free elimination, though, this isn't the cube to reach for — the swaps below do the same job without the question marks.

📏 One 10g cube makes about 450ml of stock, so a single bowl carries only a fraction of the cube's onion powder — the risk rises if you double up cubes for a stronger gravy.
