Is it harmful to take protein

Protein (concentrated protein) are organic substances composed of amino acids which are the building blocks of muscles. In bodybuilding, protein is know as a sports food, is aimed at reducing body fat mass, stimulation of muscle growth and maintaining a healthy physical shape.

Types of protein

There are several types of protein. They differ in cost and composition.


The soy protein. Stimulates the body production of the hormone thyroxine, and improves metabolism. Amino acids lysine, glutamine and arginine increase and maintain muscle mass. Some scholars argue that the isoflavones contained in soy protein, is the prevention of heart failure and cancer.


Casein. Included in the group of dairy proteins. Has a high content of glutamine, contributing to the normal functioning of the body. Due to the fact that casein is absorbed in about 7 hours, it supplies the muscles with essential amino acids. If you eat casein before going to bed, muscles all night will get food.

Whey protein. Is the most popular among bodybuilders and active lifestyle. High biological value of this type of sports nutrition is the amino acids such as leucine, valine and isoleucine. Whey protein is quickly and easily absorbed, thus contributing to the rapid intracellular protein synthesis. He was the most effective stimulant for building lean muscle mass.

Whey concentrate is the cheapest on the market. But we should remember that in its composition may include lactose and fats, which abdomen is bloated and often depart gases.

The dangers of protein

Even the useful substance, if taken improperly, have side effects. Protein protein consists of organic molecules having a relatively large size. Therefore, in rare cases, it can cause allergies.


Some people have an individual intolerance to common food products that can occur in relation to proteins. It is influenced by two factors:


- dysbiosis (disruption of the microflora of the large intestine);


- insufficient number of enzymes involved in the breakdown of certain substances.

To prevent side effects, you should take a responsible approach to the selection of proteins and carefully examine the packaging. It is also important to remember that an overdose of a concentrated protein leads to dehydration.

Also the concentrated protein intolerance can be caused by rotting of unsplit molecules in the gut. The main symptoms of this intolerance: bloating, diarrhea, abdominal pain.


Sometimes it becomes harmful, the use of proteins of unknown manufacturers. In this sports nutrition often in high doses contains heavy metals that negatively affect the body.


There is a probability that the protein will cause of renal disease. But in this case, if a person had renal failure before admission concentrated protein. To this kind of disease some people have genetic predisposition, just that she does not manifest itself and during the reception process of the protein becomes activated.


For healthy people contraindications for taking this sports nutrition do not exist, so they are absolutely not harmful to take protein.
