Guava (español: guayaba) is a tropical fruit cultivated in many tropical and subtropical regions. Psidium guajava is a small tree in the myrtle family, native to Mexico, Central America. Guavas are typical Myrtoideae, with tough dark leaves and white flowers with five petals and numerous stamens. The fruits are many-seeded berries. I was a newlywed and had just moved to Guadalajara, Mexico, when I tasted my first guayaba. I was hooked. When ripe, the guayaba, or guava, is very sweet and delicious, peeling, seeds and all. Just wash and eat it like an apple. They are also made into a popular candy called ate. (pronounced ah-tay). Guayabate is one of my favorite sweets. Among the claims for guavas are that they improve heart health; help lower blood sugar levels; relieve painful symptoms of menstruation; benefit the digestive system; are good for your skin; may aid weight loss; may have an anticancer effect; help boost immunity.
