Egg Protein: An egg is laid by a female animal. Humans eat eggs for thousands of years. It is composed of an air cell, shell, white and yolk. Eggs are one of the easiest and most inexpensive food products which are rich in proteins. Protein is the building blocks of life. It is primarily found in every cell of the human body, such as the skin, hair, muscles, and organs. Protein has six primary functions. It is vital in cell formation and repair. Children in their growing years need to grow foods which are rich in protein to help for the formation and development of new cells. Protein also contributes to the supply of energy to keep the body going. Not only will the protein build cells and tissue, but it is also involved in the formation of hormones which are body’s chemical messengers and antibodies that fight infection. Furthermore, enzymes are proteins the increases the rate of chemical processes in the body which helps in the digestion of the foods eaten to make it in its simpler form for body use. Transportation is as well a function of proteins. For example, hemoglobin is a protein that carries oxygen in the body. Protein plays a vital role in the homeostasis of all living things.
A nutritionally well-balanced diet offers adequate protein. It depends on your age and health status. Kwashiorkor is a protein-energy malnutrition that occurs when there is not enough protein in the diet. It is characterized by edema, moodiness, anorexia, fatigue, lethargy.
