Definition of Nutrition
  • Nutrition is a process for all the living creatures by intaking various materials from the environment and use to survive. I would say our body communicates with the environment.
  • The process starts at your mouth and ends at your backside:

1. Eating – getting the proper food with nutrients. In Africa there are people who eat earth, but there is not much nutrient in it. That’s why we eat plants and you eat animals occasionally in the form of food. 2. Digesting – this is the process when your body absorbs the nutrients from the food and leaves the dirt behind. It starts in your mouth. Your teeth and saliva breaks down the big chunk of food into small parts. It goes on in your stomach. There the food is already mushy (disgusting stuff, you know, if you ever vomited). From there the nutrients can enter your blood vessels. The blood transfers the nutrients to all your body cells to keep them alive and to promote cell division. 3. Excreting – separating the waste material from useful material. There are blood vessels throughout your bowel and small intestine, so everything that is useful, taken away there. When the excreta arrives at your rectum/ anus, there is very little useful material in it. It is really just shit.
