Grapefruit is the fruit of the evergreen plant of the same name, native to the tropical regions of Asia. It is a large and rounded berry, similar to an orange, with a thick and wrinkled yellow or pink peel. The internal pulp is divided into segments similar to those of the orange and varies from pink to red, with a bittersweet taste.
Grapefruit is marketed primarily as a fresh fruit, but can also be processed into juice, jams, syrups and other food products.

Grapefruit is a nutritious and healthy fruit, composed mainly of water (about 90% of the total weight) and carbohydrates (mainly in the form of sugars such as fructose and glucose). However, the fruit also contains a number of nutrients, vitamins, minerals and bioactive compounds that give grapefruit its health-promoting properties.
