Role of Proteins in Promoting Health


Proteins are essential nutrients required by the body for growth, maintenance and repair. They can be said as the building blocks of the body. The proteins are found all over the body.

The proteins are broken down into amino acids by the process of digestion. There are 22 amino-acids which can be grouped as essential and non essential amino acids. The non essential amino-acids are those that can be produced by the body. The essential amino-acids are those that cannot be produced by the body. They are obtained through food sources.

The food sources that have nine essential amino-acids are called complete proteins. The proteins that are incomplete usually lacks in one or two of the essential amino acids.
 
The main functions of proteins are fighting diseases, building and repairing body tissues, producing enzymes, hormone production, maintenance of skin, hair and nails and transporting oxygen throughout the body. The other functions include producing antibodies, maintenance of fluid balance and acid base balance in the body.

The symptoms that indicate a need for high protein foods include muscle wasting, weight loss, fatigue, frequent infections, weakness and fatigue, fluid retention, slow growth and development in children. The other protein deficiency symptoms include skin rashes, hair loss and difficulty in sleeping, nausea, headache, crankiness, moodiness, depression, anxiety and lack of energy.
 
The protein deficiency may lead to gall stones, arthritis, heart problems, muscle deterioration, organ failure and finally death. To avoid all these include turkey, tuna, shrimp, cod and venison in your diet they are excellent sources of protein. Snapper, halibut, salmon, chicken, lamb, sardines, beef, spinach, tofu, soya bean and cheese are very good sources of protein. Eat healthy and be healthy.

Take care,
