Protein shakes, protein balls, protein powder, protein supplements.. seems the world has gone a bit mad when it comes to protein. But why? Whilst we don't necessarily advocate the above products, the fact is that protein is one of the most essential nutrients. It contributes very heavily in key body functions such as the production of hormones and enzymes, immune responses and cell repair, and nobody consumes enough of it! Protein is the essential building block in blood, skin, cartilage, bone and muscles. It is a macronutrient, which means the body needs large amounts of it and since the body does not store protein, it is important to be consuming it in our diet every day.
