How to Improve Your Gut Bacteria

3. Eat a Diverse Diet

A 2019 study found that eating a varied diet helps support a stable and diverse microbiome. Each fruit and vegetable contains a unique blend of beneficial compounds, including fiber, vitamins, and minerals, that interact with and impact the microbiome in different ways.

This is especially true for prebiotic foods. Not all the microbes in the gut feed on the same kind of prebiotics, so different foods benefit the microbiome differently. Eating a variety of fruits and vegetables maximizes the benefits.
