A healthy gut contains more good than harmful bacteria. Research shows that plant-based diets contribute to diverse and beneficial bacteria in the gut. Even if you don’t want to go fully vegan or vegetarian, adding more vegetables to your diet can be beneficial. Fiber is also important to gut health, so look for opportunities to add high-fiber foods, such as legumes and whole grains, to your meals. Other factors, such as stress and sleep deprivation, can have negative effects on your gut health, so try to get enough rest and relaxation.
