The protein content of a 4-ounce serving of chicken depends upon which type of meat you are eating. Four ounces of breast meat contains 35 grams of protein, but the same amount of thigh meat has only 30 grams.
Eating four ounces of the dark meat in the drumstick provides you with 32 grams of protein. One serving of chicken provides between 17 and 70 percent of an adult's protein needs. The average adult human should make protein between 10 and 35 percent of his daily dietary food intake. A gram of protein provides four calories. If an adult eats 2,000 calories a day, between 50 and 175 grams of protein are needed.
