The microbial population of the digestive tract considerably influences proper immune response. Our bodies are designed to rely on our own physiological mechanisms, paired with the intricate action of bacteria and other microbiota, to support digestion and immunity. Leah Webb explains the ins and outs of digestion in an easy-to-understand approach, and she sheds light on the relationship between immunity, disease, microbiota, and diet. She explains what factors can interfere with healthy digestion, and she includes dietary strategies to better support immunity. Learn how avoiding grains and sugar can support a healthy digestive system (and thus a healthy immune response). Webb also discusses the ways in which the gut is connected to the brain, a relationship that directly impacts our emotions, physiological responses, and ability to feel our best.
