The typical diet must comprise all of the six essential nutrients namely: water, minerals, proteins, carbohydrates, vitamins, and fats in order for humans to stay healthy, disease-free and strong.
The informatian below shall narrow down to proteins by expounding on their significance and overall importance to the human body.
Growth and development of the body
Small children, teenagers, and pregnant women are constantly growing and developing. They therefore need plenty of proteins to fuel this growth and development. Proteins are essential for that because they are the nutrients that are converted into muscles and as such form a core component of the various organs and tissues of the body.
Once in a while the bodily tissues do get torn and worn out and hence in need of repairs. Proteins aid in the repair of the broken and worn out tissues and in so doing, ensure that the body is in the best functional conditions at all times.
The immune system protects the body against illnesses and diseases by fighting off infections such as germs and other invading pathogens. Proteins are crucial in the formation of antibodies (immunoglobulin) which tightly binds to the antigen of an invading pathogen and subsequently tagging it for attacks or directly neutralizing it.
Production of hormones and enzymes
Hormones and enzymes play very vital roles in the functioning of the various aspects of the human body. They stimulate specific cells or tissues in the human body into action and catalyze the various biochemical reactions respectively. Proteins are the key constituents of these essential chemicals of life.
Supply of energy
In the absence of carbohydrates, or in the event that carbohydrates are insufficient, proteins may be utilized by the human body to supply the needed energy. The use of proteins to supply body energy as opposed to carbohydrates is also crucial in keeping the body weight in check and also prevents other weight-related complications such as obesity, loss of mobility, and flabby muscles.
Preservation of lean mass
The term lean mass refers to everything in the human body besides body fat. It includes the organs, blood, bones, muscles, and the skin. Proteins preserve the lean mass of the human body by the virtue of being the key constituents of these parts of the body.
The benefits and overall contributions that proteins do confer to the human body are innumerable. They are the nutrients which should not miss in the diets of invalids, pregnant, lactating, and growing children.
