Bacteria are tiny creatures that live inside us, some help, some hurt. They can make you feel good or sick, depending on what they do. Imagine your body is like a house, and bacteria are the guests: some clean up, others cause messes.
Examples
- Good bacteria in your stomach help you break down food and make you feel full.
- Bad bacteria can cause tooth decay when they feed on sugar.
- Yogurt with live cultures helps keep your tummy happy.
