A 1-ounce piece of beef jerky provides 9.4 grams of protein. The Institute of Medicine, also known as the IOM, recommends 46 daily grams of protein for adult females and 56 daily grams of protein for males. Protein breaks down in the intestines into amino acids, which your body uses to build tissues and enzymes involved in the functioning of all body systems.
Your body requires fat for reducing inflammation and supporting the health of your brain. One ounce of beef jerky contains 116 calories. More than half of beef jerky's calories, 66, come from 7.3 grams of total fat. The total fat content includes 3.1 grams of saturated fat. To reduce your risk of cardiovascular disease, the American Heart Association recommends limiting saturated fat intake to less than 7 percent of total daily calories, which equals 15.5 grams or 140 fat calories, with the remainder coming from heart-healthy polyunsaturated fats -- found in vegetable oils and seafood -- and monounsaturated fats -- contained in vegetable oils, nuts, seeds, olives and avocados.
