Eat a plant-based diet

The best source of nutrition for your gut bacteria is plant food that contains fiber. Because it promotes the diversity of your gut microbiota, a plant-based diet rich in a variety of whole grains, legumes, vegetables, and fruit is beneficial for your gut health—and, therefore, for your overall health and wellness.

While animal-based diets encourage the growth of various kinds of gut bacteria than do plant-based diets. Numerous studies have demonstrated that vegetarian diets may be advantageous to the gut flora, perhaps as a result of their high fiber content. For example, a small 2013 study discovered that a vegetarian diet decreased disease-causing bacteria in obese people as well as body weight, inflammation, and cholesterol levels. According to a 2019 review, plant foods are full of specific nutrients that can raise levels of beneficial bacteria and lower dangerous ones to support gut health.
