Our body is made up of chemicals. With the help of these chemials new structures are built and energy is given to you.
The food consists of different chemical structures:
proteins, carbohydrates, fats, water, vitamins and minerals.
Long molecules can‘t get through the membranes into the body/blood…so they have to be broken down into small structures. This is called DIGESTION.
To stay healthy we need enough of all these structures…we need a balanced diet.
