What Products Contain Protein

Protein occupies a special place in human nutrition. This is the basic substance from which the cells of our body are composed. Any chemical reaction in the body occurs only with the participation of protein. To ensure normal life requires a lot of protein, it must be constantly replenished, as it is not synthesized on its own, but is introduced by eating. If the protein in the diet is not enough, the body begins to spend its own amino acids and there are violations in the body. There is a decrease in efficiency, memory worsens, people feel weak and look exhausted, muscles are destroyed. There are changes in the liver, the hormonal background, the activity of the endocrine glands can be disturbed. Immunity decreases, and there is an aggravation of inflammatory processes. Nutrients are digested worse.

The value of protein is the content of amino acids in it. In nature, there are approximately 150 amino acids. For the human body there is enough 20. In this case, 12 the body can synthesize itself, and 8 gets only together with food and therefore they are called irreplaceable. The most important of them are tryptophan, methionine and lysine.

Tryptophan is more connected with the processes of metabolism and growth, as well as tissue synthesis. Methionine regulates fat metabolism and normalizes it. Lysine is associated with hematopoiesis and its deficiency leads to impaired hematopoiesis, a decrease in the number of red blood cells-erythrocytes, a decrease in the content of hemoglobin in them. Muscles are depleted, there are changes in the liver and lungs.

The question arises, what foods contain protein? The protein is contained in all products, in some more, in others less. The protein is divided into two types: plant and animal. Both are necessary for the human body. An adult should consume at least 30% of animal protein. The total amount of protein consumed per day should be about 150 grams.

What foods contain animal protein ? The ideal source of animal protein is egg. It does not contain fat and is absorbed by the body by 92-100%. Fish, seafood, dairy products, beef are high protein foods. The most useful proteins are contained in veal, followed by beef, and afterwards the rabbit and pork meat.

What foods contain a protein of plant origin? Buckwheat occupies a special position, it contains a large amount of protein and it is recommended for dietary nutrition. Also, a lot of protein in rice, oatmeal, and in legumes. The protein is found in large quantities in wheat bread, nuts and sunflower seeds. These products have high fat content, so they are less preferred. In many vegetable proteins, the content of one, and maybe two or three, essential amino acids is not enough . Therefore, animal proteins are preferable. Vegetarians who do not consume animal fats may experience protein deficiency. At the same time, blood circulation, the exchange of fats and vitamins is disrupted, resistance to infections is reduced. Proteins of plant origin can be absorbed worse than animals.

With prolonged heat treatment, proteins can react with carbohydrates and other substances contained in foods, resulting in melanoidins that are not digested by the body. Proteins that are subjected to heat treatment, are absorbed better, but lose some amino acids.

Protein is necessary for a person, but it is necessary not to overdo it. Excess protein is very harmful to the body. The protein is burnt with time, but when a superfluous protein enters the body, the metabolic process is disturbed, after which kidney transplantation begins. If you exceed the norm when consuming protein, it is recommended to use more liquid. So, to answer the question in which products the protein is contained, it is not difficult - in all. You need to choose those products that are most useful for your body and in which it contains the most.
