About Red grapefruit

Red grapefruit is a variety of citrus fruit, originally cultivated in the Caribbean and first described in Barbados in the 18th century. Today, it is grown in subtropical regions like Florida and Texas. Known for its vibrant reddish-pink hue and tangy-sweet taste, red grapefruit is a nutrient-dense food that is low in calories (about 52 calories per half fruit) but rich in essential vitamins and minerals like vitamin C, vitamin A, and potassium. Its high water content makes it hydrating, while its fiber supports digestive health. Red grapefruit is also a source of antioxidants like lycopene, which give it its characteristic color and potential health-promoting properties.

Health Benefits

• Supports immune function thanks to its high vitamin C content (38.4 mg per half fruit).
• Promotes heart health due to potassium content (166 mg per half fruit), which helps regulate blood pressure.
• Contains lycopene, an antioxidant linked to reduced oxidative stress and potentially lower risk of chronic diseases.
• Improves skin health through its vitamin A (about 28 mcg per half fruit), which aids in cell repair.
• Aids digestion with 2 grams of dietary fiber per half fruit.
