Sweet potato, wedges, flesh and skin, baked in rapeseed oil

These sweet potato wedges are made from the flesh and skin, coated in rapeseed oil and baked. They mainly provide carbohydrate, alongside fibre and vitamin A. Per 100g, they contain 25g of carbohydrate, 5.2g of fibre, 3.9g of fat and 855µg of vitamin A, expressed as retinol equivalent.

Carbohydrate provides energy, while fibre supports normal bowel function. Vitamin A contributes to normal vision and immune function. The oil used in cooking adds fat and energy, so the amount used affects the nutritional content. For people monitoring carbohydrate or sugar intake, both the total carbohydrate and sugars figures are worth noting. Full nutritional figures are in the tables below.

About these figures

Values are per 100g of the food as described (11 samples, all imported. Cut into wedges, coated with 1.5-2 tbsp oil and roasted for 30-45 minutes). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
