In particular, we’ll talk about the food product meat.
Meat is a valuable food product. It has a lot of animal protein, which is the main structural element of all body tissues. The protein content in meat varies depending on the type and category within such limits: in 100 grams of lamb – from 15.6 to 19.8 grams of beef – from 18.6 to 20 grams, meat pork – 14.3 grams, chicken meat – from 18.2 to 20.8 grams.
Rich in meat, phosphorus, potassium, iron and other minerals: it contains almost all the vitamins. the content of B vitamins is especially high in it.
But, despite the advantages of this product, it should not be included in the diet at all, guided by the principle: the more, the better. To determine how much meat you need. use the table. There is more of it. than indicated in the table is not recommended. And that’s why. In addition to useful nutrients, meat contains purine bases, and in the process of their metabolism uric acid is formed in the body. If it accumulates a lot, the permeability of the capillaries of the renal nephrons may be impaired. develop gout, osteochondrosis and other diseases.
Recently, studies have appeared. showing that excessive consumption of meat reduces the body’s immune reactivity, and this. In turn, leads to a decrease in its resistance to various diseases.
According to the norms of rational balanced nutrition, a person needs an average of 45 grams of animal protein per day. At the same time, 100 grams of meat contains significantly less than the required norm. It is possible to fill the deficit of animal protein with fish, cottage cheese, milk, eggs.
If you eat a meat dish once a day, it is better during lunch, and for breakfast or dinner fish, cottage cheese, a glass of milk, you will fully satisfy the body’s need for animal protein.
Moreover, without any damage to health, it is possible to exclude meat from the diet 1-2 or even 3 times a week, replacing it with fish or other protein products of animal origin. Eicosapentaenoic acid is abundant in fish. reducing blood clotting, which is very important for the elderly.
You should be aware that all protein products are interchangeable.
100 grams of meat can be replaced with 175 grams of fish. 480 grams of milk. 115 grams of cottage cheese:
100 grams of fish – 60 grams of meat, 300 grams of milk, 70 grams of cottage cheese. 1.5 eggs:
100 grams of cottage cheese – 400 grams of milk. 2 eggs. 85 grams of meat. 150 grams of fish:
1 EGG – 150 grams of milk, 40 grams of cottage cheese. 40 grams of meat. 60 grams of fish;
100 grams of milk – 25 grams of cottage cheese, 20 grams of meat. 35 grams of fish. 2/3 eggs.
Many are interested in: is it possible to live without meat at all? As a specialist in nutrition, physiologist. I would answer: it is possible. Indeed, in terms of amino acid composition, an egg, for example, is even more biologically valuable than meat. and. including eggs. milk and other protein products in the diet, a person will not experience protein deficiency.
