Hooray for Hazelnuts

by KIDS DISCOVER

Oregon and Washington grow about 3 percent of the world’s hazelnuts (also known as filberts). Brought to America in 1629, the nut’s first historical mention is in a Chinese document from 2838 BC. High in fiber, vitamin E, manganese, and copper, filberts are a key ingredient in Nutella. (Ramon L. Farinos / Shutterstock)
