Parsnip, roasted in rapeseed oil

Parsnip is a root vegetable, described here with the ends trimmed and peel removed, then roasted in rapeseed oil. It mainly provides carbohydrate, along with fibre and some fat from the oil. Per 100g, it contains 29g of carbohydrate, 5.1g of fibre and 4.5g of fat, with an energy content of 668 kJ.

Carbohydrate provides energy for the body, while fibre supports normal bowel function. These roasted parsnips also provide potassium, which contributes to normal muscle and nerve function, and folate, which is needed for normal blood cell formation. The amount of oil used affects the fat and energy content, and adding salt will increase the salt content. Full nutrient figures are in the tables below.
