Protein is a macronutrient essential for building and repairing tissues, enzyme function, hormone regulation, immune support, transportation, fluid balance and can be used as a source of energy in the body.

Proteins are made up of building blocks called amino acids. They help to build and repair tissues, regulate hormones, support the immune system, transport molecules, maintain fluid balance and provide energy. 1 Proteins are found in many foods including legumes, nuts, seeds and soy products. It is important to eat a variety of protein-rich foods to get all the different types of amino acids that our bodies need.2
