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. 🌱 Try our new plant based wholefood supplement - Daily 30 *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system Learn how your body responds to food 👉 zoe.com/podcast for 10% off Follow ZOE on Instagram.

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. Today, we’re talking about the Mediterranean diet. This indulgent diet champions vegetables, beans, fish, and even red wine, all with a liberal helping of extra virgin olive oil. However, this relatively high-fat diet undergoes many regional adaptations, and the wide range of options can be confusing, even intimidating, if you’re not that confident in the kitchen. 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.

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 the true impact of these diets on your health. Today, we’re talking about the carnivore diet, a zero-carb approach centered on meat, fish, eggs, and minimal dairy while excluding all plant foods and alcohol.

Today, we’re talking about the paleo diet, rooted in the idea of emulating our hunter-gatherer ancestors after concerns about the impact of a modern westernized diet packed with highly processed foods.

Today we’re talking about the low-fat diet, popularised in the 1970s and fueled by the belief that fat was the culprit behind heart disease and weight gain. However, the aftermath saw a surge in low-quality carbs. Food manufacturers, in the quest for low-fat options, replaced fats with sugar and refined grains, resulting in us opting for low-quality carbs over whole foods and whole grains.

As we age, the distribution of our body fat changes, particularly around menopause. Most people think of body fat as bad, but fat tissue plays a number of hugely important roles in our health.

Together, they debunk the myth that fat is bad, enlighten us about why body fat is distributed where it is, and explore the differences in fat distribution between men and women. Deborah Clegg is a professor and Vice President for Research at the Texas Tech University Health Sciences Center, El Paso. Her research focuses on sex differences in metabolism, adipose tissue, and the brain and the impact this has on our health. Dr. Sarah Berry is one of the world's leading experts on human nutrition.

Admit it, exercise isn't everyone's favorite pastime. Of course, our ancestors weren't hitting the gym by choice — our evolution has wired us to stay active, and this natural activity actually slows down the aging process. The good news is that you can achieve the benefits without feeling like you're "exercising." In today’s episode, Prof. Daniel Lieberman debunks exercise myths. He also teaches us how exercise impacts our health and how learning from our evolution can unlock the secrets of a longer life. Daniel Lieberman is a paleoanthropologist at Harvard University. He’s the Edwin M. Lerner II Professor of Biological Sciences and a professor in the Department of Human Evolutionary Biology. He’s best known for his research on the evolution of the human mind and the human body.
