Cactus fruit, also known as prickly pear or tuna, is the edible fruit of certain species of cacti. It typically has a vibrant color, ranging from green to yellow, orange, or red, and is covered in small, spiny hairs called glochids. The fruit is sweet and juicy, with a flavor reminiscent of watermelon or kiwi, and is often enjoyed fresh or used in jams, jellies, and beverages. The fruit is rich in vitamins, particularly vitamin C, and contains antioxidants that can benefit health. It is commonly found in regions where cacti grow, such as parts of Mexico and the southwestern United States. Cactus fruit can be eaten raw, cooked, or blended into smoothies.
