✦ Very high beta-carotene ✦ Vitamin C ✦ Potassium ✦ Fibre source

Sweet potato is an orange-fleshed root very high in beta-carotene for vitamin A, with vitamin C, potassium, fibre, and vitamin B6. It is starchy and energy-dense but has a lower glycaemic response than many old potatoes.

🍳
Preparation note

Steaming retains more vitamin C and potassium than boiling, as less water touches the flesh.

Why are some phytochemicals missing? Nutriofia tracks over 50 bioactive plant compounds — including allicin, betanin, glucosinolates, lignans, and polyphenols — but comprehensive measurement data simply doesn't exist yet for most foods. Unlike vitamins and minerals, phytochemical analysis is still an active area of food science research. When a compound doesn't appear here, it means no published measurement exists for this food, not that the food lacks it. We update our database as new data becomes available.
