Michael reveals the best food to boost your mood, your energy levels, reduce inflammation and improve your immune system. In this episode, Michael discovers the benefits of fermented foods and their live bacteria. He speaks to Professor Justin Sonnenburg from Stanford University who’s recent clinical trial revealed that eating fermented foods can increase your gut microbiome diversity and reduce inflammation, one of the main drivers of ageing. They discuss the role of your gut bacteria in increasing the activity of key immune cells with knock-on effects across the body, and why a healthy gut microbiome is so important for feeling good. 63 year-old Donna Schwenk from California reveals how discovering fermented foods has transformed her life and given her the energy of someone decades younger.
