Growing interest in gut health has spawned a field of research that continues to make important discoveries about how previously little-understood microbes shape the well-being of the whole body. It shows how unbalanced diets and other lifestyle habits can damage them and potentially expose us to ill-health and disease. Japanese researchers studying the intestinal bacteria of 1,800 subjects identified five types of composition that can indicate health conditions. We asked experts what kind of foods and daily habits people should embrace to improve their gut health and live healthier, happier lives.
