  • 5. Protein
    • Made up of Amino Acids.
    • Amino acids are the building blocks of our bodies. Making up muscle, organs and tissues.
    • The body stores protein for muscle growth, excess protein is converted to fat and stored.
    • The body only uses protein as a main energy source if it is in distress.
  • 6. Where can we get Protein from?
