What impact does environmental exposure have according to FDN?

The chosen answer highlights a crucial aspect of Functional Diagnostic Nutrition (FDN) by acknowledging that environmental exposure can significantly disrupt biological systems and contribute to various health issues. In FDN, the understanding of health encompasses not just biological factors but also how external elements—such as toxins, pollutants, and even dietary elements—interact with the body.

Environmental factors can lead to dysfunction by interfering with hormonal balance, immune responses, and metabolic processes, which can manifest as various health concerns. This understanding is fundamental in FDN, as practitioners aim to identify and mitigate such exposures to restore normal function and health.

The other perspectives do not align with the principles of FDN. There is a significant body of research indicating the link between environmental influences and health, making the notion that these factors are irrelevant to overall health clearly inaccurate. While mental health can be affected by environmental exposures, to state that it solely affects mental health ignores the comprehensive impact these factors can have on physical health as well. The idea that environmental exposure strengthens the immune system contradicts the evidence showing that many environmental toxins and stressors can lead to immune system dysregulation rather than enhancement.
