Zero nitrogen balance refers to the equilibrium state between the body’s nitrogen intake and excretion.
Nitrogen balance refers to the dynamic balance between protein synthesis and metabolism in the body, mainly based on the amount of nitrogen ingested and excreted by the body, reflecting the relationship between nitrogen ingested and excreted by the body. Nitrogen balance includes zero nitrogen balance, positive nitrogen balance and negative nitrogen balance.
Under normal circumstances, the healthy adult body is in a stable state, the daily intake of nitrogen only to meet the renewal of their own tissue protein, the rest of the protein through the metabolism to produce energy and nitrogenous wastes discharged from the body, the performance of nitrogen intake and discharge roughly equal, known as the zero-nitrogen balance, i.e., B = 0.
Nitrogen intake than discharge nitrogen is positive nitrogen balance, i.e., B & gt; 0, mostly seen in children, pregnant women, patients in recovery and athletes, etc., in order to meet the body’s need for additional protein.
When the intake of nitrogen is less than the discharge of nitrogen, it is negative nitrogen balance, i.e., B<0, which is mostly seen in starvation, disease and the elderly, and the negative nitrogen balance should be actively improved in order to maintain a healthy body state and promote the recovery of the disease.
About the specific content of zero nitrogen balance, please consult the relevant physician, to actively maintain a healthy body state, to avoid negative nitrogen balance.
