Grapefruit is known for its bitter and tangy taste, and is often eaten for breakfast or as a snack. It is also commonly used in salads and drinks, as well as in cooking and baking. Grapefruit is high in vitamin C, fiber, and antioxidants, and is considered a healthy addition to any diet.

The grapefruit grown in Turkey is typically round or oval in shape, with a yellow or pinkish-red rind. The flesh of the fruit is usually pink or red, and is juicy and acidic in flavor. Some popular varieties of grapefruit grown in Turkey include the Star Ruby, Rio Red, and Marsh Seedless.
