How inflammation could age you with Prof. Philip Calder

5/16/2024
Inflammation is a complicated topic. Short-term inflammation plays an essential role in fighting infections and healing injuries. But too much inflammation can be a catalyst for chronic ailments, like heart disease, type 2 diabetes, autoimmune disorders, rheumatoid arthritis, and obesity. What we eat can influence our inflammatory responses and contribute to chronic, low-grade inflammation. In today’s episode, Prof. Philip Calder helps us understand the science behind inflammation, how it impacts our health and what food has to do with it. Philip is head of the School of Human Development and Health, as well as a Professor of Nutritional Immunology, in the Faculty of Medicine at the University of Southampton. He’s also an internationally recognised researcher on the metabolism and functionality of fatty acids. His work focuses on the roles of omega-3 fatty acids and the influence of diet and nutrients on immune and inflammatory responses.

The best exercise routine, according to your muscle clocks with Professor Karyn Esser

4/4/2024
Our bodies naturally follow a roughly 24-hour cycle, called our circadian rhythm. And every cell has a rhythm. As we get older, we tend to lose muscle, making us more prone to falls and less able to live independently. Though we can't stop aging, staying active helps keep our muscles strong and our bodies healthy for longer. Prof. Karyn Esser is a specialist in how the body's natural rhythms affect muscles. Today, she guides us through the latest research and shows that it's always possible to harness the power of your muscles to enhance your quality of life. She is a professor in the Department of Physiology and Aging at the University of Florida, where she’s also the co-director of the University of Florida Older Americans Independence Center. In today's episode of ZOE Science & Nutrition, Jonathan and Karyn explore the body's internal clocks and ask: why do our muscles have their own schedule, and is there an ideal time of day to exercise?

In today’s episode of ZOE Science & Nutrition, Jonathan speaks with Dr. Will Bulsiewicz, ZOE’s U.S. medical director, to learn more about this flourishing area of research — and the best ways to identify and treat histamine intolerance.

1/24/2024
Each day this week, we examine one of the world’s most popular diets. Putting the latest scientific evidence under the microscope, we’ll discover these diets' true impact on your health.

Does calorie counting improve your health?

Each day this week, we’re examining one of the world’s most popular diets. Putting the latest scientific evidence under the microscope, we’ll find out these diets' true impact on your health.

In this special episode of ZOE Science & Nutrition, Jonathan is joined by Christopher Gardner, Professor of Medicine at Stanford University and the Director of Nutrition Studies at Stanford Prevention Research Center.
