Abstract
On Earth, we find an amazing number of creatures living together. Each creature is unique. All of them interact together, without borders, making this world—our world—a beautiful place to live. Bacteria are tiny organisms present almost everywhere, including on and in our bodies. Gut bacteria have a strong communication with the brain. A correct communication between gut bacteria and the brain is important for adequate mental health. Situations that damage our gut bacteria are able to harm our brains. Moreover, mental stress can damage bacteria living in the gut. We need to take care of our gut bacteria. A balanced diet, including fish, vegetables, cereals, fruits, and water can help our gut bacteria to be healthy. Healthy gut bacteria will have a positive effect on the brain and our moods. “Happy gut bacteria” will help us to have “happy brains.”

Summary
Bacteria are very tiny creatures that are difficult to see without a microscope. Bacteria are present in what we eat and touch. We have more bacteria than human cells in our bodies. There are drugs that can kill bacteria or prevent them from growing. It is important to take antibiotics only if it is really necessary, in order to keep the good bacteria alive. Each part of the human body has different types of bacteria. The human microbiota is the group of microorganisms living in and on the human body
