A healthy gut microbiome is essential for good digestion and good health in general however this doesn’t mean we should be taking supplements of beneficial bacteria or eating yoghurt. For most people the problem isn’t that they’re missing a species of beneficial bacteria but that they don’t have optimal amounts of it. So instead of going out of ones way to consume such bacteria only to have them die off as soon as they reach the unhealthy gut home that awaits them it’s best to first create an environment conducive to the survival of these bacteria which will allow them to reach and maintain optimal numbers on their own. The way to do this is to live a healthy lifestyle with adequate sleep, sunlight, and physical activity; and to eat a plant based diet abundant in healthy prebiotics, e.g., fresh fruits and vegetables, which provide the raw materials needed for your beneficial bacteria to thrive.
