Prebiotics

Which foods contain prebiotics?

Updated 4 Nov 2026

Short answer

Garlic, onion, chicory, asparagus, Jerusalem artichoke, tomatoes, wheat, barley and rye contain prebiotics.[1] The amounts in these foods are low, so some prebiotics are made on a large scale and added to products.[1] For inulin, the food industry often uses Jerusalem artichoke tubers and chicory roots.[2]
