In that barely-monitored process of declaring national holidays, the National Mango Board and National Papaya Board ended up as the monthly national holidays in June.
Mango and papayas are both tropical tree fruits, but from different parts of the tropics. While both are now cultivated worldwide:
Mango originated in South Asia.
Payapa is native to Central America and southern Mexico.
As with all fruits, there are different cultivars (varieties), but all have a sweet, fragrant aroma and creamy flesh (ripe papayas have softer flesh than ripe mangoes).
In terms of ease of eating: mangoes have a long, flat, single a pit, while papayas have lots of bead-like black seeds.
Enjoy them guilt-free: Mango and papaya are nutritionally rich tropical fruits with favorable calories: papaya at 55 calories/cup, mango 54 calories per half cup.
