About Grapefruit slice

Grapefruit is a citrus fruit believed to have originated in the Caribbean in the 18th century. A staple in various cuisines, particularly American and Mediterranean, it is known for its tangy and slightly bitter flavor. Grapefruits are low in calories, with about 52 calories per half fruit, and are packed with essential nutrients. They are an excellent source of vitamin C, providing over 50% of the daily recommended intake per serving, and also supply fiber, potassium, and antioxidants such as lycopene and flavonoids. Grapefruits also contain small amounts of vitamin A and several B vitamins, making them a highly nutritious addition to a balanced diet.
