Sweet potato is exceptionally rich in beta-carotene (more than enough for daily vitamin A), with useful fibre, vitamin C, vitamin B6, manganese, and potassium. It has a lower glycaemic impact than most white potatoes when boiled or steamed, particularly with the skin on.
Boiling or steaming gives a lower glycaemic response than baking or roasting; eat with the skin and a little fat (such as olive oil) to enhance beta-carotene absorption.

Glycemic Index & Load
Medium GI food — moderate effect on blood sugar. Pair with protein, fat, or fibre to lower the overall meal GI.
Glycemic Load (GL = GI × carbs ÷ 100) accounts for portion size. A moderate GL — portion size matters here.

* % 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.
