Gut bacteria line your entire digestive system, but most live in our intestines and colon, they make what’s known as microbiota or microbiome. They help process food and affect everything from your metabolism and appetite to your mood, sleep, and immune system.
Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair. Our body systems function efficiently thanks to the food we eat, the water we drink and the air we breathe. Digestion is important because your body needs nutrients from food and drink to work correctly and stay healthy!
