Certain foods and healthy lifestyle habits can improve your gut health naturally.
1. Eat Fiber-Rich and Probiotic-Packed Foods
Fiber is a plant-based nutrient that reduces the risk of metabolic diseases by stimulating the growth and diversity of good bacteria in the gut, research suggests. Sweet potatoes, spinach, beets, carrots and fennel are full of naturally gut-enhancing fiber. Besides fruits and vegetables, whole grains are a rich source of fiber, too.
Fermented foods like yogurt, kimchi, sauerkraut and kombucha are also prized for their gut-boosting abilities, thanks to the presence of probiotics. Yogurt specifically may help calm gastrointestinal conditions like diarrhea, inflammatory bowel disease and constipation. One study found people who eat yogurt regularly have more lactobacilli, a gut-benefitting bacteria, in their intestines, as well as fewer enterobacterium, a type of bacteria linked with inflammation.
2. Consider a Supplement
Probiotic supplements have become increasingly popular as word of the importance of gut health continues to spread. While probiotic supplements aren’t a panacea for gut health, there’s some evidence they can give the microbiota a boost and restore gut health under certain conditions.
Your doctor may also recommend a probiotic supplement if you’re prescribed an antibiotic. Evidence suggests this may help prevent antibiotic-associated diarrhea.
If you’re interested in a probiotic supplement, talk to your doctor. While such supplements have a history of apparently safe use, especially in healthy people, the risk of harmful effects is greater in people with compromised immune systems.

3. Exercise Often
Movement is medicine for so many parts of the human body, including the microbiome. In both animal and human studies, researchers have found that exercise promotes an increase in diversity of healthy bacteria in the gut.
While several studies highlight the roles exercise and diet can play together in positively impacting gut health, a 2019 review specifically reported that exercise has the potential to alter gut bacteria composition and functionality independently of diet. Researchers found longer workouts and high-intensity aerobic training, in particular, contributed most to gut bacteria diversity and function in relation to overall wellness. They also observed that lean people are more likely to reap the gut health benefits of exercise than individuals with overweight or obesity.
4. Limit Your Alcohol Intake
Drinking too much may negatively affect your microbiome, too. Repeated alcohol use is linked to gastritis, an irritation of the gut in which it becomes inflamed. Such inflammation can lead to heartburn, chronic discomfort, ulcers and bacterial infections.
Drinking too much is also associated with intestinal inflammation, which is a sign of an unhealthy gut. Research suggests that this kind of inflammation alters the microbiota—including how well it works—and can throw it off balance.
5. Reduce Stress Levels
Stress isn’t just mental: Think about those butterflies you feel when you’re excited or anxious. Experts in gut health often cite the “gut-brain connection” and refer to the gut as “the second brain.” While we don’t know everything about their relationship, we do know that mental health and the gut are intimately connected.
Research suggests anxiety and depression are affected by the gut and vice versa—they can increase the risk of IBS, and people with IBS are more likely to experience these mental health disorders.
Finding ways to manage your mental health and stress levels may help reduce uncomfortable GI symptoms and get your body back in balance. Don’t know where to start? Try adding some physical activity to your day. Something as simple as a daily walk might improve gut health, as research suggests exercise can increase the quality and quantity of health-boosting gut microbes.
