CAUTION: This episode contains references to skipping meals and may be triggering for those with eating disorders.Today’s guest believes that the decisions we make every day about what we eat have a huge influence on our health. Dr William Li is a medical doctor and the author of the international bestseller, Eat to Beat Disease: The Body's Five Defense Systems and the Foods That Could Save Your Life. He works in a field of research called Food as Medicine and having been involved with the development of many different drugs over the past few decades, he is passionate about using scientific rigor to analyse the specific benefits of food.We discuss the five health defence systems that exist within our bodies: angiogenesis (growing of new blood vessels), stem cell regeneration, the gut microbiome, DNA protection and the immune system. These systems maintain our health and help us heal when disease damages our body. Dr Li explains how specific foods can strengthen these natural defence systems.We talk about cancer, how tumours grow, and where food can play a role in terms of prevention as well as part of the treatment. Dr Li shares the research about the amazing benefits of green tea for cancer prevention. We also talk about the impact that fasting has on various health systems within our body.Dr. Li’s ground-breaking work is really changing the way we look at how food impacts our health and I think that by the end of this conversation, you will look at food through a different lens. And I'm pretty sure that it's going to inspire you to make a few changes next time you go to the supermarket - it certainly did for me.
