Gut flora

Gut flora are like tiny little friends that live in our tummies and help us digest our food. They are made up of billions of tiny microorganisms, like bacteria, yeast, and viruses. When we eat food, our gut flora help break it down and turn it into things our body can use, like vitamins and energy.

Just like having good friends is important to make us happy, having a good balance of gut flora is important for our health. When we have too many bad bacteria and not enough good ones, it can make us feel sick or give us tummy troubles. Eating a healthy diet and taking probiotics can help keep our gut flora happy and healthy, and keep us feeling good.
