Answer:
Nutrients
Explanation:
All food that we eat is composed of three basic chemical substances (proteins, fats, carbohydrates) called nutrients.
Digestion is the process of breaking down these substances to simpler components (amino acids, fatty acids, sugars) by the enzymes from saliva, pancreas and intestines. These simpler components are then absorbed and used by our cells. These nutrients are essential for human life, normal growth, development and health.
