High Protien Diet and How do Protien Diet Works

Unlike carbohydrate, an average meal poorly responds to the need of body for protein. So a high protein diet plan is prescribed to meet the protein demands of the body. It is a must irrespective of age or sex as they are the body building and body repairing materials in the form of tissues.

For a growing child, even a proper diet falls short of the daily requirement and gradual lacking shows in the retardation of growth. The protein requirement in the diet is higher when new tissues are being laid down for growth, development or repair. It rises during pregnancy and breast feeding and is higher in infants and children.

How the high protein diet work in the body:

Proteins are complex structures. They can be utilized by the body if they are split into simpler forms. These simpler nitrogenous compounds are called amino acids. Proteins differ in food value according to the amounts and types of amino acids which they contain.

Nutritionally, amino acids belong to two categories.

Essential amino acids: They cannot be synthesized in the animal body and must be supplied with foods full of protein in adequate amounts.
Non essential amino acids: These amino acids may be synthesized in the body . They need not be supplied in the diet.

Eight amino acids are considered essential for human nutrition. These are

• Methionine
• Threonine
• Tryptophan
• Valine
• Leucine
• Isoleucine
• Lysine
• Phenylalanine

Ariginine and histidine are considered semi indispensable amino acids. Glycine, alanine, serine, cysteine, tyrosine, proline, aspartic acid and glutamic acid are some of the non essential amino acids.

Besides forming proteins, dietary amino acids are required for the formation of products like heme of hemoglobin, the hormones adrenalin and thyroxine, the skin pigment melanin, and essential parts of nucleic acids.

Some amino acids give rise to carbohydrates in the body. Amino acids are also catabolised to give energy.

Food proteins should include sufficient amount of animal proteins such as milk, egg, fish and meat proteins because they contain adequate amount of all the essential amino acids.
