Protein

  • Protein is essential for growth and repair of the body and maintenance of good health.
  • Protein also provides energy; 1 gram provides 17 kJ (4 kcal).
  • The Reference Nutrient Intake (RNI) is set at 0.75g of protein per kilogram bodyweight per day for adults.
  • The amount of protein we need changes during a lifetime.
  • Different foods contain different amounts and different combinations of amino acids (the building blocks of proteins). Protein from animal sources (e.g. meat, fish, eggs and dairy products) contains the full range of essential amino acids needed by the body. However, vegans and vegetarians can get all the amino acids they need by combining different plant sources of protein, e.g. pulses and cereals.
