Protein – The building block of life

Protein is the main building block of life: it is fundamental to the structure and functions of our body's cells. Its origin can be animal or vegetable. Proteins are made up of simpler elements (called amino acids) linked together.
8 of these amino acids are defined as "essential" because our body is not able to synthesise them and we must therefore get them from our food.
Maintaining adequate protein intake is also important as you age: 25% of healthy women over 60 years of age consume less protein than their daily requirement.
If you are vegetarian or vegan, it is important that your diet contains a wide variety of plant-based foods.

Sources include
  • Beans, lentils, peas
  • Dairy foods
  • Eggs
  • Lean meat, skinless poultry
  • Nuts, grains, legumes
  • Seafood (e.g. salmon, trout, sardines)
  • Tofu

It is important to have a varied and balanced diet and healthy lifestyle.
