Protein is one of three primary macronutrients that provide energy to the human body, along with fats and carbohydrates. It is composed of amino acids that are essential for proper body function and serve as the building blocks of body tissue.
There are 20 different amino acids in total. While some can be produced by the body, there are nine essential amino acids that must be obtained from dietary sources. Foods that provide all of these essential amino acids are called complete protein sources, which can include both animal and certain plant-based foods.
A diet rich in high-quality, clean protein supports good health, muscle recovery, and growth. However, not all proteins are created equal. If you are vegan, vegetarian, or simply reducing animal products in your diet, it can be challenging to get the quality protein you need. This is where a daily protein smoothie makes sense. In less time than it takes to prepare a bowl of cereal, you can blend a great-tasting protein smoothie that keeps you energized and satisfied for hours—while also helping your body build and repair lean muscle tissue.
