Most pears (about 95%) sold in the U.S. are grown on the west coast, in Washington, Oregon, and Northern California. The Bartlett is the most popular variety of pear in the United States. Pears were given the nickname "butter fruit" in the 1700s because of their soft, buttery texture. Pears are an excellent source of fiber and a good source of vitamin C for only 86 calories per serving. They are sodium, fat, and cholesterol free. That’s a lot of nutrition in one sweet and juicy package!
