In this episode, I’m joined by Dr Will Bulsiewicz, a gastroenterologist and leading expert on the gut microbiome, to explore why the health of our gut matters so much to our overall health. Will explains what the gut microbiome actually does, and why it has such a powerful influence on the body. We explore why so many of us aren’t getting enough fibre, how quickly the microbiome can respond to changes in our diet, and why eating a diverse range of foods matters. Will also explains the four key components of an anti-inflammatory diet, including fibre and resistant starch. We talk about the surprising benefits of foods such as green bananas and cooled potatoes, and why supporting your gut involves much more than taking a probiotic. We discuss ultra-processed foods and restrictive diets, including why removing foods can sometimes improve symptoms without necessarily addressing the underlying health of the gut. Will explains what it takes to rebuild a healthy and diverse microbiome, and why small, consistent changes can make a difference. Will shares his own experience of emotional healing, and we explore the relationship between our physical and emotional health. We discuss how unresolved experiences can sometimes affect the body, and why feeling heard and understood can be an important part of the healing process. If you’ve ever wondered what your gut is really doing for your health, or why gut health is about so much more than digestion, this conversation will give you plenty to think about. 🌱 Want to feel better and live more?
