What is Protein and The Top 10 Protein High Foods You Should Eat According To Nutritionists

Protein is an essential building material for our body. Every cell, tissue and organ includes protein. In addition to the building features protein may also be a source of energy. And in case there is an excess of protein, liver gradually converts it into fat, which is deposited as a reserve in our body. Out of 22 amino acids vital for a human being, 13 can be synthesized independently from the existing construction material, and 9 can only be received with food. During the process of absorption proteins are divided into amino acids, which in turn are available in different parts of our body to perform their core functions. Proteins (as amino acids) are included to our blood as parts of the hormone system, regulating water and acid-base balance and affecting growth and development of the body. Depending on their specialization, proteins have different functions in our organism. Transport proteins, for example, are engaged in the delivery of vitamins, fats and minerals. There are also proteins that fight infections as antibodies to various diseases.

Recommended protein daily need for adults is 0.8 grams per 1 kg of body weight. However, you should calculate your own daily value according to the tables for calculating ideal body weight. The actual weight of the person in this case is not considered due to the fact that amino acids are used for cell mass of the body, rather than fat. According to the rules of nutrition, protein foods should be about 15% of total calories in the daily diet. But this amount may vary depending on the type of human activities and the state of person’s health. A person should increase consumption of proteins during illness, especially in the recovery period, during heavy physical labor, in the cold season, when the body spends more energy for heating, during intensive growth and development, during sport events, as well as preparation to them. Protein requirement can be reduced during warm seasons (this is due to the chemical processes that occur in our body when it is influenced by heat), with age (the older we are, the less protein we need), for people who suffer from violation of protein digestibility, etc.

Interaction Of Protein With Nutrients

Everything in nature is interconnected, and so are all the elements of our body. Proteins, as a part of the overall system cooperate with other elements like vitamins, fats and carbohydrates. And in addition to the simple interaction, proteins are also involved in transformation of one substance into another. As for protein absorption, vitamin C is an essential component for this process. That is why every gram of protein takes 1 milligram of vitamin C to be digested and absorbed.

Protein Deficiency

Protein deficiency can hardly bring any harm to a person who consumes lots of calories and amino acids. However, people with poor diet, especially from the third world countries, often experience protein deficiency, which leads to weakening of their immune system, muscle and heart diseases. Young children who need to consume increased doses of protein are the first in the group of risk. Symptoms of protein deficiency are weakness and lack of energy, low resistance to various infections, nervous and cardiovascular system disorders, slowing growth and development in children.

Dietary Toxicity of Protein

Extreme and long-term consumption of protein may result in kidney problems or osteoporosis. The tolerable upper intake of protein is not set.
