bacteria

Your body is home to trillions of bacteria? Yup, that's right! But don't worry, not all bacteria are bad. In fact, there a lot of varieties of "good" bacteria that live in your gut. This good bacteria, also known as probiotics (you've probably heard of them), can help your digestion, boost your immune system, and yes, even improve your mood. Eating a diet rich in fiber and fermented foods, like yogurt and kefir, can help promote the growth of good bacteria.
