Proteins play a major role in ensuring your health well being. There are innumerable functions of proteins in the body. Well, the primary functions of proteins include building and repairing of body tissues, regulation of body processes and formation of enzymes and hormones. Read further to explore information about protein role in health…

Proteins aid in the formation of antibodies that enable the body to fight infection. Proteins serve as a major energy supplier. There are distinctive kinds of proteins, each performing a unique function in the body. Proteins form a major part of your body, next to water.

The composition of proteins in the body is like that muscle contains about 1/3 protein, bone about 1/5 part and skin consists of 1/10 portion. The rest part of proteins is in the other body tissues and fluids. Even blood contains loads of proteins. In fact the hemoglobin molecule is nothing but proteins.

Our body requires proteins for the purpose of maintenance and healthy growth. The need for consuming proteins is especially more for infants, young children, pregnant women and recovering patients. There is a constant breakdown of proteins in the body and this explains the reason why we need to consume proteins on a regular daily basis. It becomes of prime importance to ensure that you have your daily-recommended protein intake, so as to improve your health fitness.

[h=1]Recommended Daily Protein Requirements[/h]Protein is one of the most important components of every cell present in the body. A complex, high-molecular-weight organic compound, it has an unsurpassed content of amino acids. There are a number of benefits associated with proteins. Right from improving body composition and building muscle to repairing tissues and preventing bone loss, the list goes endless. Besides this, much of the fabric of our body, such as muscle, cartilage, ligaments, skin and hair, is constructed from protein molecules. We all know that a high-protein diet is essential for an individual, but the question is - how much is enough?

An ongoing debate, experts have been studying to determine exactly how much protein does our body require? Many health organizations have conducted regular studies; so as to work out, what should be the recommended daily protein intake. The suggested requirement varies from person to person. For instance, the protein requirement for adults is different from that of young growing children. There are multiple factors, which need to be taken into consideration, while deciding the recommended daily protein intake, such as, age, sex, physique and activity level.

The human daily protein requirement is calculated on the basis of 'ideal body weight'. Based on height and gender, the ideal body weight is calculated. The daily protein requirement is calculated in terms of grams per day for every kilogram you weigh. For a person who is accustomed to sitting or taking little exercise, the recommended daily protein intake is 0.75g per kg of body weight. A person whose physical activity level is good enough and who performs exercises for about an hour or so, for them the ideal protein intake is about 1.0-1.2g of protein per kg of body weight.

In case of athletes, however, the recommended protein requirement differs. Apart from a greater lean mass and greater need for tissue repair, they burn a small amount of protein, during physical activity. As such, athletes have a higher protein requirement. For those engaged in endurance training, the protein intake should be about 1.2-1.4g of protein per kg of body weight, while for athletes, who are engaged in strength training, the daily recommended protein requirement is approximately 1.6-1.7g of protein per kg of body weight.

[h=1]Egg Protein Content[/h]Egg protein is very rich in quality and it is due to this fact that manufacturers of protein powders often base their products on egg protein. Egg protein contains all the essential amino acids that the human body requires. Talking about the egg white and yolk proteins, it can be said that one large egg contains about 6.5 grams of protein, out of which egg white protein content is about 3.6 grams. But yolk also contains fats and owing to this fact, many people tend to avoid eating egg yolk.

Here is a table that depicts as to how much protein is in an egg, so check out egg protein content

Food High in Protein

Proteins form an important nutrient component of the body. Made up of essential and non-essential amino acids, it helps in building and repairing muscles and bones, restoring body cells, providing a source of energy and controlling many of the important metabolism processes in the body.

Our body gets the protein from the food we eat. Unarguable, proteins derived from animals, in the form of meat and milk, have the highest concentration of protein in them. This is because it contains all nine of the essential amino acids. Vegetable protein, on the other hand, lacks one or more of the essential amino acids, which is why it is considered incomplete.

For a vegan or vegetarian, one needs to consume a wide variety of protein-rich vegetable foods, so that he/she can get all their essential amino acids. To know more about the foods that have high protein content, browse through the table given below.

[h=1]Protein Content of Milk[/h]
Milk definitely serves as one of the most excellent sources of proteins and this can be attributed to its rich quality protein content. Though it doesn't contain a large quantity of proteins, but the quality of proteins that it provides the body, is simply amazing. Protein in milk contains all the essential amino acids that the body requires.

[h=1]Protein Digestion & Absorption[/h]Digestion of proteins takes place in different stages. The initial phase of protein digestion and absorption occurs in the stomach and the latter takes place in the small intestine. Proteins provide the body with amino acids, which are required by the body, but unfortunately, the body is incapable of producing them by its own. Well, the protein digestion process basically consists of the breakdown of proteins into amino acids. Read further to explore information about protein absorption rate…

There are distinctive kinds of enzymes that aid in the digestion and absorption of proteins. The enzyme called pepsin does its work in the stomach and it works best when the stomach is acidic. It breaks down the large protein molecules into smaller ones. It is here where the proteins get partly digested in the body.

In the small intestine, there are other enzymes that take over the charge of protein digestion in the body. These enzymes aid in protein absorption, by breaking the small protein molecules into amino acids. Protein absorption rate is faster for animal origin foods, rather than vegetarian plant origin foods, perhaps because vegetable proteins usually contain cellulose covering.

[h=1]Benefits Of Whey Protein[/h]Before knowing the benefits of whey protein, you need to first know, what exactly is it? During the process of conversion of cow's milk into cheese, a by-product is formed. This by-product is known as whey. It has a large collection of globular proteins, which when extracted forms whey proteins. Whey proteins are a rich source of the essential amino acids and make exceptional protein choice for adults, children and infants. In its pure form, Whey proteins contain little or no fat, lactose and cholesterol. Though whey proteins are mostly considered useful in terms of building muscle, you will be surprised to know that the benefits go beyond improving body composition. In the following lines, we have provided information about the benefits of whey protein.

Benefits Of Whey Protein

  • The amino acids present in the whey protein prove to be essential for the growth of healthy muscles, nails, skin and other connective tissue, thereby helping in improving body composition and enhancing athletic performance.
  • Whey protein is helpful for the repair and growth of muscle tissue, mainly necessary after a workout.
  • Consumption of whey protein proves beneficial for athletes as it increases the levels of glutathione, thereby enhancing the immune function.
  • Whey protein is a rich source of the essential amino acid, leucine, which plays a dominant role in promoting muscle protein synthesis and muscle growth.
  • Whey proteins are useful for cancer patients as well. While undergoing chemotherapy or radiation, patients often face difficulty in having a balanced nutritional diet, thereby losing weight or facing protein calorie malnutrition. Whey proteins are easy to digest and very gentle to the system and thus, make an excellent protein choice.
  • Since whey proteins have almost negligible fat, lactose and cholesterol, they are beneficial for patients diagnosed with diabetes, especially Type 2. It helps control blood glucose levels and is effective in case of weight management as well.
  • Research suggests that whey proteins contain a number of components that are found in human breast milk. It is key ingredient found in all the infant formulas. For those who cannot breast feed their child, infant formulas, containing whey protein is the best option to explore.
  • For aged people, consumption of whey protein helps prevent bone loss. A diet, rich in whey protein, would help keep bones and muscles healthy and strong.
  • While recuperating from wounds and surgical incisions, our body requires a lot of proteins. Being rich in content, whey protein is the most preferred choice.
  • Another effective benefit of whey protein is that it helps in supporting both healthy weight-loss, as an appetite suppressant and muscle enhancing nutritional programs.
