We Are Never Alone: Living with the Human Microbiota
The human body is inhabited by millions of tiny living organisms, called human microbiota. Bacteria are microbes found in our skin, nose, mouth, and especially, in our gut. We acquire them during birth and the first years of life, and they live with us throughout our life. They are involved in our healthy growth, in protecting our body from invaders, in helping digestion and in our mood. Some changes may occur during our growth depending on the food we eat, the environment where we live, the people and animals that interact with us, or medicines we take such as antibiotics. Human microbiota help us to keep healthy, but in special occasions they can also be harmful. We need to take good care of our microbiota to avoid the development of some diseases, such as obesity and asthma. We should eat healthy food that contribute to develop the good microbiota.
