What Are Proteins?

Proteins are essential macromolecules composed of amino acids, which are the building blocks of life. They play critical roles in various biological processes, including enzymatic reactions, structural support, transport of molecules, and immune responses. Proteins are synthesized in cells based on genetic instructions encoded in DNA. There are 20 different amino acids, and the specific sequence of these amino acids determines a protein’s structure and function. Proteins can be categorized into two main types: fibrous proteins, which provide support and shape, and globular proteins, which are involved in metabolic activities. A balanced diet includes protein sources such as meat, dairy, beans, and nuts.

Protein is in every living cell in the body. Our bodies need protein from the foods we eat to build and maintain bones, muscles and skin. We get proteins in our diet from meat, dairy products, nuts and certain grains and beans.

Proteins from meat and other animal products are complete proteins. This means they supply all of the amino acids the body can't make on its own.

Plant proteins are incomplete. You must combine them to get all of the amino acids that your body needs.

It is important to get enough dietary protein. You need to eat protein every day, because your body doesn't store it the way it stores fats or carbohydrates. The average person needs 50 to 65 grams of protein each day. This is the amount in four ounces of meat and a cup of cottage cheese.

To optimally preserve your lean body mass while losing weight, it is extremely important to consume some type of lean protein at every meal.

Protein is a great nutrient to prevent you from overeating because it will fill you up quicker. It is also another nutrient that is energy costly which means it takes more calories to digest and utilize protein than it does a carbohydrate.

Your best sources of protein are beef, beans, chicken, lentils, fish, broccoli, corn, eggs, chickpeas, artichoke and dairy.
