Grapefruit juice, unsweetened

Unsweetened grapefruit juice is the liquid obtained from grapefruit. The figures cover juice sold in cartons, cans and bottles, as well as frozen juice. It consists mainly of water, with carbohydrate supplied as sugars. Per 100g, it provides 140 kJ of energy, 8.3g of sugars and 31mg of vitamin C.

Vitamin C supports normal immune function and helps the body absorb iron from plant foods. Unsweetened juice still contains sugars, which contribute to energy intake, and it provides only trace amounts of fibre. Grapefruit juice can interact with some medicines, increasing their levels in the blood and the risk of side effects. Full nutrient figures are shown in the tables below.
