5 Important Functions of Protein in Your Diet

About 10 to 35 percent of your daily diet should be based on protein — this fact alone signals the importance of protein in your diet. Protein builds, maintains, and repairs your tissues. And this explains why physically active individuals should consume protein. Protein also helps in the immune process and strengthens the immune system. Moreover, all enzymes and essential hormones are proteins.

Protein is the bedrock of all the cells in the body, and this macronutrient plays a vital role in many processes taking place in our bodies. Here are five essential functions of protein in your diet.

Tissue and Muscle Formation

Protein is fundamental to the building and repair of all body tissues from the cellular level to the hair and nails. A protein-deficient diet can lead to muscle wasting and several other negative outcomes. When we exercise, the muscles suffer micro tears. In the process of repairing these tears, the muscles will become enlarged and stretched, leading to muscle gain. The immune process that triggers the healing process requires the presence of protein, making it vital for anybody who wants to gain muscle mass.

Enzyme Composition

Enzymes are made up of protein which catalyzes chemical reactions in the body by binding to molecules. Enzymes are essential to many processes in the body including contraction and relaxation of muscles, the release of energy by breaking down adenosine triphosphate, digestion of food, and transmission of nerve impulses.

Hormone Production

There are several glands in the body that secrete hormones, chemicals that are released in one part of the body to coordinate activities in other parts. Hormones such as insulin and oxytocin are made up of protein and serve important functions in blood sugar levels regulation and stimulating of contractions during childbirth. Hormones can also help activate muscle growth by stimulating protein production or reducing the breakdown of the macronutrient.

Energy Boosting

During the process of digestion, protein is broken down into amino acids. Protein can help improve satiety and make you feel fuller longer by increasing the levels of leptin, the satiety hormone, and reducing the levels of ghrelin, the hormone controlling hunger. However, the body will often use carbs for energy even when protein is available. It’s important to eat a balanced diet rich in lean protein foods such as fish, white poultry, and beans as well as high-fiber complex carbs such as grains and vegetables and healthy fats like avocados and olive oil to enjoy optimal energy always.

Immunity Bolstering

The immune system is made up of antibodies which are a form of specialized protein molecules that provide a specific immune response to certain foreign agents. The body produces these proteins after exposure to antigens such as bacteria and viruses. Protein also forms a significant part of the immune system defense mechanism that combats invasive agents through inflammation and creating holes in the cells of the pathogens among others.

Protein is a lifesaving nutrient you should always have on your plate. Whether from animal, plant, or supplement sources, make sure you are getting adequate amounts of protein in your diet.
