Why are salivary tests important in FDN?

Salivary tests hold significant importance in Functional Diagnostic Nutrition because they provide an accessible and non-invasive method for evaluating hormones and metabolic function. Through salivary analysis, practitioners can assess the levels of various hormones, including cortisol, testosterone, estrogen, and progesterone, among others. This information is crucial for understanding an individual's hormonal balance and stress response, which are key factors influencing overall health and wellbeing.

Additionally, hormone levels in saliva often reflect the bioavailable form of hormones that are actively interacting with tissues, offering insights into how well the body's metabolic processes are functioning. By analyzing hormone patterns, practitioners can identify imbalances that may contribute to various health issues, allowing for targeted interventions that address the underlying causes rather than just treating symptoms.

The other options do not pertain to the primary function of salivary testing in FDN. While blood pressure measurement, brain activity assessment, and skin condition identification are essential aspects of health evaluation, they do not align with the unique benefits that salivary tests provide in the context of hormone and metabolic assessment.
