Proteins exist in all the organisms. The cells need proteins to carry out all its functions. Amino acids form these proteins which are organic compounds. The process of formation of protein is carried out in the stomach when food is broken down and digested. The metabolic activity in the body requires proteins. Calories, which we know as the energy, are produced from protein, fat and carbohydrates from the food that we take. Dairy products in various forms including cheese and milk, eggs, nuts, legumes and meat are the main source of proteins. The food particles are broken down in the stomach continuously from which proteins are derived. The proteins are broken down through digestion by enzymes. The estimated requirement of protein of women are said to be lesser than men. While the men require 56 grams of protein per day, the women require 46 grams of protein per day. When the intake of protein is lower than the required intake, protein deficiency sets in.
Protein deficiency causes a number of health problems and may prove to be fatal. Kwashiorkor is a protein deficiency disease. It expresses itself with symptoms as diarrhea, apathy, fatty liver, failure to grow, edema of the legs and belly, flaky skin, and inactivity. Mental retardation is also known to be caused by protein deficiency. Poor people who face chronic hunger and nutritional deficiency are known to be the most susceptible. Those who are dieting and are on crash diet for weight loss also may face protein deficiency at times. Older people could develop protein deficiency when they do not have a balanced diet. A similar situation might also occur in people who are recovering from surgery, trauma or illness. The deficiency can be offset by the intake of protein rich food or special diet.
There are a variety of dietary supplements in the market containing carbohydrates, proteins, fats, minerals and vitamins. The source of protein is often soy, casein or whey. Flavors are added to make them tasty. These dietary supplements are available as energy drinks or energy bars. Energy bars offering primarily proteins are also available. Pure Protein Bars are also available in the market. These have more protein than other ingredients. Protein bars come in a variety of mouth watering flavors.
Such supplements give both calories and proteins. Pure protein enters into the body to offset the deficiency.
Protein is an important requirement for our bodies. Thus, we should all ensure that we have enough protein in our daily diet.
