Humans are living longer than ever — but longer life doesn’t always mean better health. More than half of U.S. adults are living with at least one chronic condition, such as diabetes, heart disease or obesity. So what can we actually control to help prevent these diseases as we age? And what should we be eating to stay healthier, longer?

On this episode of On Nutrition, cardiologist Dr. Stephen Kopecky breaks down 11 foods linked to longevity and shares practical strategies for healthy aging from his book, Live Younger Longer.

Why are habits so hard to build — and even harder to break? And do they really have to be perfect to improve your health?

On this episode of On Nutrition, Mayo Clinic dietitian Tara Schmidt sits down with health coach Jenn Trepeck to explore the science of habits and how small, realistic changes can lead to lasting results. From decision fatigue to mindset shifts, they break down why so many health goals stall — and what actually helps them stick.

They also discuss the role of health coaching, how habits evolve over time, and why flexibility — not perfection — may be the key to long-term success.

Whether you’re trying to eat better, move more or reset your routine, this episode offers practical strategies to help you build habits that work in real life.

On this episode of On Nutrition, transplant clinical dietitian Heather Bamlet explains how she supports transplant patients and shares strategies to help prevent — and in some cases, even reverse — certain liver diseases.

Food is more than the sum of its parts. Nutrients in supplements act differently than the same nutrients in whole foods. The way those nutrients are packaged, bonded and processed all factor into what’s known as a food matrix.

On this episode of On Nutrition, we talk with Sally Cummins, a registered dietitian and senior vice president of nutrition affairs at the National Dairy Council. She shares the science behind the dairy food matrix and explains how you can see the food matrix at work in everyday foods.

Stress, uncertainty and unmet emotional needs can influence eating patterns in ways that go beyond hunger.

On this episode of On Nutrition, holistic nutritionist and health coach Ali Shapiro joins host Tara Schmidt, R.D.N., to discuss the root causes of emotional eating, how physiology and psychology interact, and practical strategies to pause, identify needs and build self-trust over time.
