The 100-Year Diabetes Mystery: How Our Environment Made Us Sick

Are you tired of the narrative that a diabetes diagnosis is simply a failure of willpower? Join Richie and Amber, a registered dietitian and certified diabetes care and education specialist, as they investigate the systemic roots of the modern diabetes epidemic. A century ago, diabetes was a rare condition. Today, impaired glucose metabolism affects nearly half of the adult population in the United States.

In this comprehensive episode of The Diabetes Podcast, we break down the environmental shifts that caused this massive health crisis. We explore the historical timeline, starting with the loss of incidental daily movement and the collapse of dietary fiber intake. We uncover how the dietary fat panic of the 1970s led to a surge in ultra-processed foods and high fructose corn syrup, fundamentally altering human gut microbiomes and driving chronic inflammation.

Type 2 diabetes is a complex, multi-system condition. It’s not one broken thing… it’s a whole lot of things affecting a vast network that includes the liver, muscles, pancreas, fat tissue, gut, and brain. Elevated blood sugar is simply the output—it is the fever, not the disease itself. By understanding how chronic stress, sleep deprivation, and a lack of physical education in schools act as environmental triggers, we can remove the shame associated with metabolic disease and start advocating for real change.

We encourage you to advocate for systemic health policy changes by contacting your local, state, and federal representatives. You can find their contact information at https://www.usa.gov/elected-officials.
