 This week on the podcast, Mikki speaks to Dr Sarah Hancock, a public health researcher whose work sits at the powerful intersection of oral health and metabolic disease. In this conversation, Sarah unpacks the often-overlooked links between what’s happening in our mouths and what’s unfolding systemically in the body.They explore how gum disease and blood sugar dysregulation are deeply intertwined, why your dentist might be the first person to flag insulin resistance, and how the microbiome of the mouth plays a much bigger role in chronic disease than we’ve given it credit for.

Sarah also challenges conventional public health approaches which you’ll find super interesting.

This is an eye-opening episode for anyone interested in prevention, systems thinking, and redefining the silos of health.
