Are Healthy adults are in a state of positive nitrogen balance.?

Yes, healthy adults are generally in a state of positive nitrogen balance, which means that the amount of nitrogen consumed through protein intake exceeds the amount excreted through urine and other means. This balance is essential for growth, tissue repair, and maintenance of muscle mass. Factors such as adequate protein intake, physical activity, and overall health contribute to sustaining this positive state. However, during periods of stress, illness, or malnutrition, individuals may shift to a negative nitrogen balance.
