Spanish rice and refried beans

Protein is a very important component of our diet and should make up 15-25% of our daily energy intake. Protein is necessary to maintain our cells – it plays a role in the structure, functioning, and maintaining of all the cells and tissues, from our heart to the muscles in our feet. Protein also acts as a transporter and messenger.

Proteins are made up of many smaller units known as amino acids, which bind together in a particular sequence to tell the protein what it’s role is. There are 20 amino acids, and some of these are unable to be made by the body. These are known as essential and must be consumed through food.

There are many different foods sources of protein, such as meats, fish, eggs, nuts, seeds, lentils, and legumes, dairy foods, and grain foods. Animal products are sources of complete proteins, which means they contain all the amino acids.

Incomplete sources of protein also exist, and these have low amounts or do not contain all of the essential amino acids. This is more common in plant-based food sources of protein, such as lentils, legumes, and cereals. Eating 2 or more of these incomplete proteins together forms a complementary protein – a protein that then contains all the essential amino acids required by our bodies in sufficient amounts.
