Think about a protein-rich diet and you might think of buff men and women flexing in their active wear. But the truth is that protein has so many vital roles in the body and we all need it!

What is protein?

Protein is a macronutrient is and is made up of amino acids. Protein is responsible for muscle growth and repair, as well as being needed to make hair and nails, and for the production of enzymes important for digestion and thyroid health.

Where to find it

The richest sources of protein are poultry, seafood, meat and eggs. Other protein containing foods include dairy products such as yoghurt, cheese, milk, protein powder, as well as nuts, seeds, tofu, tempeh, legumes and beans.

Five reasons to eat more protein

  1. Protein can aid weight-loss and weight maintenance
    High protein diets have been shown to be effective in weight-loss(1) because protein helps you feel fuller for longer. This my help to curb the desire to snack.
  2. Helps to regulate blood sugar
    Having protein regularly throughout the day can help regulate blood glucose (sugar) levels (2). Fewer dips in blood glucose levels helps reduce cravings and energy slumps throughout the day.
  3. For stronger nails and hair
    Protein is important for the structure and development of strong hair and nails because it is involved in the growth of cells and cell renewal (3).
  4. It has mental health benefits
    Protein is made of amino acids which are used to make feel-good hormones such as serotonin and dopamine. Getting enough of these is important in maintaining a balanced mental state (4).
  5. Protein supports recovery from exercise
    When you exercise, your body breaks down muscle tissue. Protein is responsible for repairing tissues and builds muscle ensuring that your body becomes stronger (5)
