Magnesium plays a critical role in both short-term survival and long-term health, particularly in DNA repair processes. Inadequate magnesium intake can lead to a gradual accumulation of DNA damage, increasing the risk of mutations and cancer over time. As DNA repair mechanisms slow with age, the lack of magnesium exacerbates the potential for cellular dysfunction and chronic diseases. Understanding this connection highlights the importance of maintaining adequate magnesium levels for overall health.
