Protein is in many foods that we eat on a regular basis. [1] Protein is manufactured in the body but only in small amounts, so we need to consume regular dietary protein. Fortunately, protein deficiency is extremely rare in the developed world. Protein is a vital part of our bodies. The most obvious proteins most of us would recognize are our muscles.[3]
Protein is the fundamental building block for our muscles and it is essential that these same muscles be supplied with a daily dose of high quality protein. This is especially true for those who are exercising on a regular basis.[4] Protein is the best known component of whey and is made up of many smaller protein subfractions such as: Beta-lactoglobulin, alpha-lactalbumin, immunoglobulins (IgGs), glycomacropeptides, bovine serum albumin (BSA) and minor peptides such as lactoperoxidases, lysozyme and lactoferrin. Each of the subfractions found in whey has its own unique biological properties.
Nutrition experts recommend a diet with a variety of protein foods but for optimal results make sure that one of them is whey protein. Nuts are rich in arginine, an amino acid needed to make a molecule called nitric oxide that relaxes constricted blood vessels and eases blood flow. They also contain vitamin E, folic acid, potassium, fiber, and other healthful nutrients.[16]
Protein is initially broken down in the upper small intestine, just outside the lower stomach, using an enzyme manufactured there called trypsin. Once broken down, protein best is best absorbed in that first 12 to 18 inches out of the stomach.[1] Protein is one of the easiest nutrients to get. [2] Protein is made up of amino acids, often described as its building blocks. We actually have a biological requirement for amino acids, not for protein.[3]
Protein is important to have in your diet; the question is how much protein is needed? It’s no secret that diets recommending higher protein intake are still popular, but research doesn’t lie. Protein is also critical for optimum immune function. When deprived of protein, the body is more susceptible to allergies, infection, and disease.
Protein is an essential building block for muscle, blood, skin, hair, and nails. We need it for muscle repair, for building natural immunities, and for proper growth and development.
Protein is required for building and repairing muscle. But that doesn't necessarily mean that strenuous training, be it strength, speed or endurance work merits the need for extra protein.[7] Protein is the stuff children grow big on, the stuff with which our bodies knit themselves back together after surgery, the stuff of which we're made. Small wonder, then, that its derivation is the French proteine , or primary substance, from the Late Greek proteios , primary, from Greek protos, first. Protein is one of the most important parts of dog food, as well as one of the least understood by the average dog owner. Most people have the misconception that the amount of protein the food contains is the important factor.
Protein is one of the big three macronutrients. The other two are carbohydrate and fat.
Additionally, protein powders can be sprinkled on cereal, stirred into soups or stews, and cooked into baked goods. [17] Additionally, it underscores the importance of increasing protein intake during energy restriction to conceivably promote losses in body fat. [18]
Egg White Protein is extracted from pure egg whites then processed into powder form. High in protein, this powder can be used by everyone.[23] Egg whites have been determined to have the highest biological value of 100, which means that all of the absorbed nitrogen from egg white protein can be retained and used by the body. Since the amino acids found in plants are biologically different from those found in humans and animals, the biological value of plant protein sources is considerably lower.[24]
