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.
