Grapefruit juice
Grapefruit juice is a drink made by pressing this large citrus fruit, with its characteristic taste that is both tangy and slightly bitter. It comes in several forms: pure cold-pressed juice, juice from concentrate, or pink and white versions depending on the variety of fruit used. Refreshing, it fits well at breakfast or as a snack. At around 40.9 kcal per 100 g, it is moderate in calories compared with other fruit juices, while providing natural carbohydrates and water. Its nutritional appeal lies mainly in its vitamin C content and its contribution to hydration, which makes it an interesting option in a varied, balanced diet.

Tips
To get the most from grapefruit juice, choose freshly squeezed juice over versions made from concentrate, which often have sugar added. A sensible serving is a small glass (about 150 ml), ideally drunk with your morning meal. Drink it soon after pressing: its vitamin C and aromas are sensitive to air and light.
Nutrition facts and benefits. With 40.9 kcal and 8.41 g of carbohydrate per 100 g, grapefruit juice has a lighter profile than many sweetened nectars. It contains little protein (0.52 g), almost no fat and very little fibre (the whole fruit pulp provides more). Its glycaemic index remains moderate, but like any juice, it concentrates natural sugars without the filling effect of the flesh of the fruit.
Ways to enjoy it. You can combine it with other citrus fruits to vary the flavours, or use it in cooking for marinades, fruity sauces or tangy vinaigrettes. Compared with an orange soda high in added sugar, it is a better choice. To vary your drinks shelf, also try orange juice and lemon juice, also enjoyed for their freshness.
For active people. Grapefruit juice can go with a snack thanks to its quickly available carbohydrate, useful around exercise to replenish stores. You can add it to a post-training shaker or drink it with a source of protein for balanced recovery. Think about hydration too: juice diluted in water lowers the sugar concentration while still quenching your thirst.
Weight control. Even when natural, juice is still a sugary drink to be enjoyed in moderation: one glass a day is generally enough. If your goal is weight loss, choose the whole fruit, which is richer in fibre and more filling. Avoid having several glasses a day, as liquid calories add up quickly. To go further, explore the rest of the drinks family and check the food calorie table to compare your choices day to day.
