Citrus × paradisi, commonly known as grapefruit, is a hybrid fruit that originated from a cross between the pomelo and sweet orange. It is characterized by its large size, thick skin, and juicy, segmented flesh, which can range in color from pale yellow to deep pink. Grapefruit is known for its tangy and slightly bitter flavor, making it a popular choice for breakfast or as a refreshing snack. Grapefruit is rich in vitamins, particularly vitamin C, and contains various antioxidants. It is often consumed fresh, juiced, or used in salads and desserts. Additionally, grapefruit can interact with certain medications, so it's important for individuals on specific treatments to consult with a healthcare provider before consuming it.
