Lemon juice, fresh, weighed as whole fruit

Fresh lemon juice is the liquid extracted from lemons. These figures describe the juice obtained from whole fruit, with amounts expressed per 100g of whole lemon rather than per 100g of juice. It mainly provides water, with small amounts of carbohydrate and some vitamin C. On this basis, it contains 32g of water, 0.6g of carbohydrate and 13mg of vitamin C.

Vitamin C supports normal collagen formation, which is important for skin, blood vessels and other tissues. It also helps the body absorb iron from plant foods. Fat, saturated fat and salt are recorded as trace amounts. Full nutrient figures are provided in the tables below.
