Jerky is lean trimmed meat that has been cut into strips and dried (dehydrated) to prevent spoilage. The word "jerky" derives from the Quechua word ch'arki which means "dried, salted meat".
One cup of beef jerky pieces has 369 calories, 30 grams protein, 23 grams fat, and about 10 grams carbohydrate. There are about five grams of fat in a single piece of beef jerky. The fat is a blend of saturated fat and monounsaturated fat. Beef jerky is a good source of protein providing almost seven grams per piece.
Unopened jerky should be stored in a cool, dry place like a pantry or a drawer. Sunlight and heat can affect beef jerky's freshness and flavor, so anywhere dark and cool will help extend the life of your favorite treat.
