Bacteria in your gut 

Improving your gut microbiota

Good and bad bacteria thrive in your intestines. Interestingly, what you eat greatly affects the types of bacteria that live inside you. Here are several ways to improve your gut microbiota:
Follow a diet rich in whole foods.Eat plenty of fruits, vegetables, beans, and legumes, as they are rich in fiber that promotes the growth of good gut bacteria.Eat fermented foods, such as plain, natural yogurt.Avoid eating sugary foods and drinks.Eat prebiotic foods which promote the growth of good gut bacteria.Eat whole grains, as they contain non-digestible carbs.Take a probiotic supplement.
