What should you eat when everyone disagrees about nutrition? In this episode, Dr. Dariush Mozaffarian, cardiologist and director of the Food is Medicine Institute at Tufts, joins Dr. Rhonda Patrick to reexamine the evidence on saturated fat, red meat, seed oils, and the true drivers behind the obesity epidemic. He also explains how the GRAS loophole allows food companies to introduce additives without FDA review, and makes the case for using healthcare dollars to expand access to nutritious, minimally processed foods.

One cup of blueberries a day can improve vascular function, support the aging brain, and tighten glucose control in ways that go far beyond antioxidant activity. In this episode, Dr. Rhonda Patrick breaks down how blueberry anthocyanins and their downstream metabolites act as signaling molecules that support endothelial function and memory, while long-term studies link regular blueberry intake to slower cognitive decline and lower dementia risk. She also details the evidence for post-meal glucose control and insulin sensitivity, and explains why blending blueberries with bananas may reduce polyphenol availability.

The next 10 years may add decades to human lifespan by compressing the time it takes to understand, treat, and prevent disease. In this episode, Dr. Derya Unutmaz explains why accelerating AI could transform drug discovery, shorten clinical trials, and push cancer treatment toward increasingly personalized interventions. He also reframes AI not as an existential threat, but as a medical enabler that doctors may soon be ethically obligated to use.

The strongest anti-aging strategy may be less about dramatic reversal and more about removing what accelerates aging in the first place. In this episode, Dr. Steve Horvath maps out the science behind biological age and how aging clocks are changing the way researchers evaluate longevity interventions.
