PROTEIN in our diets

Next to water, protein is the most plentiful substance in the body.

Protein is one of the most important elements for the maintenance of good health and vitality and is of primary importance in the growth and development of all body tissues.

It is dieting the major source of building material for muscles, blood, skin, hair, nails and internal organs, including the heart and the brain.

Protein is needed for the formation of hormones which control a variety of bodily functions such as growth, sexual development and rate of metabolism.

Protein also helps prevent dieting the blood and tissues from becoming either too acid or too alkaline and helps regulate the body´s water balance.

Enzymes, substances necessary for basic life functions, and antibodies, which help fight foreign substances in the body, are also formed from protein.

In addition, protein is important in the formation of dieting milk during lactation and in the process of blood clotting.

As well as being the major source of building material for the body, protein may be used as a source of heat and energy, providing four calories per gram of protein.

However this energy function is spare when sufficient dieting fats and carbohydrate s are present in the diet.

Excess protein that is not used for building tissue or energy can be converted by the liver and stored as fat in the body tissues.

During digestion the large molecules of proteins are decomposed into simpler units called amino acids.

Amino dieting acids are necessary for the synthesis of body proteins and many other tissue constituents.

They are the units from which proteins are constructed and are the end products of protein digestion.

Foods containing protein may or may not contain all the essential amino acids.

When a food contains all dieting the essential amino acids it is termed “complete protein”.

Foods that lack or are extremely low in any one of the essential amino acids are called “incomplete protein”.

Most meats and dairy products are complete protein foods, while most vegetables and fruits are incomplete-protein foods.

To obtain a complete protein dieting meal from incomplete proteins, one must combine foods carefully so that those weak in an essential amino acid will be balanced by those adequate in the same amino acid.

In adults protein deficiency may result in lack of vigour and stamina, mental depression, weakness, poor resistance to infection and dieting slow recovery from disease.

The body loses protein when particular bodily stresses such as surgery, injury or prolonged illness have occurred.

At times of such body stress it is necessary to consume extra protein order to rebuild worn out tissues.

However, excessive intake of protein may cause fluid imbalance.
