Answer:
Carbohydrates
- is the main source of energy of your body. They help you fuel your brain, kidneys, heart muscles, and central nervous system.
Protein
- A lot of your body is protein. Your muscles are just about all protein, and most of your organs are protein. Many of the chemical reactions in your body are speeded up by other types of protein. Your body can make some of the components of protein by itself, and it must get some of the components from outside of the body.
You need protein daily for your tissue to repair itself, normal function, and perhaps to grow.
Vitamin
- Vitamins allow your body to grow and develop. They also play important roles in bodily functions such as metabolism, immunity and digestion.
