👉 Nitrogen plays a crucial role in the body's defense mechanisms, particularly in the context of infections. It is a key component of amino acids, which are the building blocks of proteins essential for the immune system's function. During an infection, the body requires increased nitrogen to produce antibodies and other immune proteins that help fight off pathogens like bacteria and viruses. Additionally, nitrogen is vital for the synthesis of nucleic acids (DNA and RNA), which are necessary for the replication and repair processes of cells, especially those of the immune system. However, an imbalance in nitrogen levels can impair these functions, making the body more susceptible to infections. Therefore, maintaining optimal nitrogen levels is crucial for a robust immune response.
