  • Protein
    • Needed for growth and repair of the body.
      • fundamental structure in the body and involved in a wide range of metabolic reations.
    • 1g  provides --- 4 kcal
    • Amino Acids
      • proteins are made up of long chains of amino acids.
        • adults need 8 of theses amino acids:
          • such as levcine, valinel, lysine and theronine
    • Complementary action of proteins
      • so when two foods providing vegetable protein are eaten at a meal, such as a cereal (e.g. bread) and pulses (e.g. baked beans), the amino acids of one protein may compensate for the limitations of the other, resulting in a combination of higher biological value.
