It's no secret that protein plays one of the main roles in human nutrition. All chemical processes in the body occur with the participation of this critical component. Unfortunately, a person cannot independently produce protein. Meanwhile, it contains amino acids, without which the vital activity of the body is impossible.
However, it must be emphasized that each person has an individual need for this component. It depends on the degree of physical activity, age, gender of the person. Everyone knows how important protein is for athletes. This is the main building material of the cell. Protein must be present in the daily diet of children. However, far from all adhere to a healthy diet, while not having the slightest idea of which foods contain proteins.
Proteins of both plant and animal origin are equally important to humans. Their ratio depends on the age criterion, as well as on the specific living conditions in which the person is.
All young fathers and mothers should be required to know which foods contain animal proteins, as they form the basis of nutrition for infants. The diet of an adult should include at least 30 percent of the above building material of the cell (animal origin). In women who are pregnant, as well as at the stage of breastfeeding, this indicator should be about 70 percent.
So, what foods contain proteins? Of course, this is meat. This food product has long been considered a storehouse of the considered high molecular weight organic substances. A very important clarification is needed here. Meat products are sources of protein of an animal, not a plant origin. It should be borne in mind that only lean meats are recommended for a healthy diet: young lamb, veal, beef, as well as chicken and turkey.
What foods contain proteins yet? Of course, these are fish, seafood, as well as cheeses, cottage cheese, kefir and low-fat milk. A typical low-fat protein is egg. Much less of this substance is found in red meat, including ham, smoked meats, sausages, and sugar.
If we talk about a protein of plant origin, then its greatest amount is found in buckwheat, rice and oatmeal. The above products are recommended for weight loss. Also in abundance, the main building material of the cell is found in beans and peas. How much protein is in foods called legumes? In lentils, for example, the vegetable protein content is about 35 percent, in beans - more than 20 percent.
In addition, vegetable protein is found in abundance in rye bread. A huge amount of the above component is found in nuts and sunflower seeds. However, these products have a lot of fats, so they are less preferred from the point of view of dietetics.
To summarize, we can absolutely summarize that a healthy diet should be balanced, that is, it should contain products of both plant and animal origin. Only in this case, the body will not experience protein deficiency.
