The avocado is thought to have originated in Southern Mexico, but the fruit was cultivated across the Rio Grande down to central Peru centuries ago. Most varieties are pear-shaped and can range in skin color from yellow-green to green to a dark purple that is almost black in appearance. Avocados are sodium and cholesterol- free, and low in calories. They are also a good source of Vitamins B, C, E, and K, as well as fiber and folic acid.
