Theoretically, adults can achieve zero nitrogen balance by consuming about 30 grams of protein every day, which means that nitrogen intake is equal to nitrogen excretion. However, considering other factors such as safety, digestion and absorption, 0.8 g protein per kg body weight per day is appropriate for adults.
