In this solo episode of the Diet Doctor podcast, I delve into the scientific links between our diets and their effects on physical health, brain function, and societal well-being. Drawing on historical perspectives, we examine how human diets evolved from nutrient-rich, diverse meals of hunter-gatherer societies to modern processed and refined food systems.

We discuss the gut-brain axis and its role in mental health, how nutrient deficiencies affect mood and cognitive function, and the systemic issues that drive rising rates of obesity and chronic disease. By understanding these connections, we can identify pathways to healthier individual choices and more sustainable societal changes.

This episode provides a science-backed exploration of how food shapes our bodies, minds, and communities, offering insights for anyone seeking to make informed dietary choices.
