What is Protein

What is protein?

Protein is a vital nutrient made up of chains of amino acids. There are 22 different amino acids and the body needs them all. Amino acids are chemical compounds (made of carbon, hydrogen, oxygen, & nitrogen) that are combined in various forms for the body to use.

The 22 amino acids are divided into 2 groups consisting of 8 essential amino acids and 14 non-essential amino acids.

Essential amino acids are ones the body is unable to synthesize on its own from other compounds. Therefore, we must obtain them through diet. With non-essential amino acids, the body is able to synthesize them. However, making non-essential amino acids is conditional by are consumption of essential amino acids. In other words, the body needs essential amino acids to produce non-essential amino acids.

Proteins are found in meats, fish, eggs, nuts, and dairy products. It's important to consume a variety of proteins so your body will get a variety of amino acids it needs to function well.

Functions of Protein

Protein has multiple functions for our body.

Proteins produce enzymes. Enzymes are protein molecules that are used as a catalyst to create chemical reactions that are essential for the body to function. These functions include digestion, supply energy, transfer nutrients, and filter wasteful products.

Producing enzymes is one of the most important functions of proteins as they are important for systems and processes in our body. For example, proteins will help strengthen our immune system by producing antibodies, proteins help with digestion, and help with the transfer & absorption of nutrients to the blood.

Along with carbohydrates and fats, protein is an important source of energy our body needs for cellular function. They maintain, grow, and repair cells in our body. This is important for healthy tissue and muscles.

Is too much protein bad?

Too much protein can cause issues with your liver and kidneys, particularly with your kidneys, because kidneys are important for metabolism. They filter out wasteful products. Having too much protein will cause your kidneys filtering process to work harder, which can create problems later in life.
