✦ Quercetin ✦ Sulphur compounds ✦ Prebiotic fibre ✦ Mild flavour

Shallots are small, mild alliums with a flavour between onion and garlic. They are richer in quercetin and sulphur compounds than common onions, and provide prebiotic fibres and small amounts of vitamin C.

Preparation note

Use raw and freshly peeled in dressings and salads to keep vitamin C and quercetin; slice just before use to limit oxidation.

* % Daily Value is the proportion of an adult EU Nutrient Reference Value (NRV) supplied by 100g of this food. NRVs are the labelling standard — the same basis as the “%RI” figures printed on food packaging — so these percentages are directly comparable with a shop label. They are a single adult figure and do not vary by age or sex, which is why they sometimes differ from UK dietary reference values: the NRV for vitamin C is 80mg where the UK RNI is 40mg. When Nutriofia assesses your own intake in the reports and trackers, it uses the age- and sex-specific UK values instead.

Fibre is shown without a percentage. Our fibre values use the UK Englyst NSP method, while the published 30g daily goal is an AOAC figure — the two are measured differently and a single percentage would mislead. How we source and normalise our data →
