Proteins are essential nutrients present in all living organisms. They help in the development of organs, tissues, muscles, and hormones in the body. They are a great source of energy and support in the growth and functioning of our body. It is necessary to consume a high-protein diet while doing physical exercises. However, proteins are made up of a highly complex substance which takes a lot of effort to break itself down completely into energy. Hence, consuming excess protein put a lot of pressure on the liver and kidney thus ultimately causing harm to our body.

Protein

Protein is made up of highly complex amino acids that are involved in the chemical processes that generate energy. Protein is derived from the Greek word ‘proteios’ which means “holding the first place.” This name was given by a Swedish chemist, Jöns Jacob Berzelius who recognized it in 1838. Proteins are important for our body and it consists of twenty amino acids. There are different types of proteins and these differ from one species to another and one organ to another.

Nutritional Value of Protein

Proteins are large compounds having a good amount of nutritional value. They are formed by the combination of smaller amino acids and contribute energy equivalent to 4 calories per 1 gram of protein to the body. Our daily diet generally consists of 10-35% proteins, which fulfill our daily requirement. It is usually recommended that one should take 1 gram of protein per 1 kg of body weight, in order to stay fit.

Side-Effects & Allergies of Protein

Many people who want a very good muscle growth jump on taking a high protein diet which causes many side-effects in the body. Too much consumption of everything is bad and may lead to severe health complications. High-protein/low-carb diets are also considered as a weight loss technique and many people without taking advice from a doctor or nutritional experts start consuming a lot of proteins. The intake of protein should be much lower than carbohydrates and when people take a greater amount of protein; their metabolism changes into a state called ketosis, which means the body converts from burning carbohydrates for fuel to burning its own fat. Ketosis suppresses appetite and people start eating less. It also occurs in diabetes and it disturbs body's elimination of fluids resulting in a loss of body’s water weight.
