Bacteria are the most abundant form of life on the planet. They are found in most every environment, from Antarctic ice, to boiling hydrothermal vents, to inside your stomach. Most of these do not hurt us. Actually, many of these organisms are very important to our survival.
Bacteria help many animals to digest food, they help trees grow, and they are important in the recycling of nutrients in the environment. They are also used in biotechnology applications to produce everything from food to energy to clean water.
There, they help to digest substances that the human body cannot break down, like many carbohydrates and things called short chain fatty acids. It is important that we keep this population healthy. Eating probiotics can help to replenish good gut bacteria. On the other hand, taking unnecessary antibiotics can hurt this community. When this happens, we often get symptoms like diarrhea or stomach pain.
