Guava is a tropical fruit that is native to Mexico, Central America, the Caribbean, and South America. It is a small tree in the myrtle family and is cultivated in many tropical and subtropical regions. The most frequently eaten species is the apple guava, which is round or oval and has a pronounced and typical fragrance, similar to lemon rind but less sharp. The outer skin may be rough, often with a bitter taste, or soft and sweet. The flesh inside is sweet and juicy, with a flavor that is a cross between pineapple and strawberry, with flesh similar to a pear. Guava is typically eaten fresh or made into beverages, jams, and other foods. It is also used in an array of jelly-like desserts, pies, pastries, as a sauce, to glaze meat and serve fresh. Guava is a source of vitamin C, fiber, and other substances that act like antioxidants. Guava leaves also contain chemicals with antioxidant and other effects.
