There are many things that can change your gut microbiota. The first thing I thought about was your diet. I’m aware that fermented foods like kimchi, yogurt, pickles, and kombucha all contain good probiotics that feed the bacteria in your gut with good nutrients. This allows your gut bacteria to grow and flourish more. Taking a probiotic supplement also helps maintain a proper ecosystem for you gut bacteria to live in.
A behavior that is important for good gut health is regular exercise. Studies have shown that increased exercise also increases the abundance of beneficial microorganisms. Sleep is also an important aspect in controlling healthy gut bacteria. Lack of sleep results in the imbalance of certain bacteria ratios in the gut which can be detrimental to ones health. Smoking is another factor that changes the gut micro biome populations and ultimately leads to the risk of developing Crohn’s Disease.
