Three macronutrients provide energy and structural material to the body: carbohydrates, fats, and protein. As protein is an essential ingredient to many functions, it is important to eat enough every day. Unfortunately, there is conflicting information out there about how much protein to consume and which foods are the best sources. It may take people some time to find the right amount of protein for their body type, but doing so can bring many benefits.
Proteins are the building blocks of the body. They're made up of amino acids, which are linked together and then folded to make complex shapes. The body can create non-essential amino acids. Essential amino acids are those the body cannot make on its own; it must consume these through diet. Protein helps build muscle and is also a component of enzymes, hormones, skin, organs, and the immune system.
