Original title: How to correctly understand the nutritional advantages of dairy food
Reasonable diet can effectively improve the nutritional status of the human body, good nutrition is to protect the body's immune function of the material basis, enhance the ability to resist viral infection, help to deal with the prevention and treatment of neo-coronary pneumonia. Reasonable diet is a balanced diet composed of diversified foods, and the nutritional advantages of dairy food are more prominent in the special period of "war epidemic" for all.
is a natural food with rich nutrients, suitable composition ratio, easy digestion and absorption, and high nutritional value. The main common in the market are liquid milk, yogurt, cheese, milk powder and so on. Dairy mainly provides protein, calcium and vitamin B1, B2 and so on, is a good source of calcium, high-quality protein in the diet. The average protein content in milk is 3%, the protein of milk is a high-quality protein, the proportion of essential amino acids is in line with the needs of the human body, so the biological utilization rate in the body is very high. Lactose in milk can also promote the absorption of minerals such as calcium, iron and zinc. Lactose, protein and fat are partially broken down in fermented yogurt and are more easily absorbed by the body. At the same time, fermented yogurt contains a wealth of probiotics, which have many health benefits.
In the fight against the "new crown pneumonia epidemic" in the very period, dairy food with its unique nutritional rich, easy to eat, easy to carry, easy to reserve and other advantages, especially suitable for the general public daily consumption, especially for pregnant women, breast mothers, children and the elderly and other special groups, as well as the struggle in the "war epidemic" front line of health care workers and patients, pay more attention to the intake of dairy food, in order to protect basic nutritional needs and enhance the body's immunity. It is recommended that adult dairy intake be at least 300 grams of liquid milk per day or a significant amount of milk powder and appropriate amounts of dairy products.
In addition, experts remind that in the case of controlled residential areas, limited access to the home, families can take advantage of limited out-of-home procurement opportunities, priority purchase and storage of dairy food, at this time need to pay attention to the following points: In general, sterilized packaging liquid milk can be preserved for a longer period of time, nutritionally and ordinary fresh milk is not significantly different, can be properly purchased and stored. Yoghurt needs to be refrigerated and usually has a shelf life of more than two weeks. In the absence of liquid milk, full-fat milk powder can be selected. Cheese is also an important dairy product, is the dairy casein manufactured products, low moisture content, high protein content, easy to transport, suitable for long-term preservation, can also be used as a choice of dairy food.The guarantee of high-quality protein intake is an important dietary principle to enhance the body's immunity to viral infections
since Italian scientists isolated gluten in 1742, human exploration of the importance of protein to life has never stopped. Protein as one of the most important components of the human body, all cellular tissues of the human body contain protein, protein is the essential nutrients of the human body, is the material basis of life. In the course of life activities, protein plays the role of the implementer of various functions, its main physiological functions are three aspects:
1, composition and repair of tissue organs;
2, the composition of biologically active substances in the body to regulate physiological function;
3, maintain the normal function of immune function;
4, the supply of energy, no life without protein.
protein is composed of amino acids, natural proteins have 20 amino acids, of which 8 amino acids (lightine, isoestine, lysine, methionine ( methionine), phenylalanine, suline, tryptophan, proline) is essential amino acids, can only be obtained from food and not synthesized in the body (infants and histamines).
, the number and variety of essential amino acids in food proteins become a measure of protein advantages and disadvantages. The nutritional value of food protein depends on the type and quantity of amino acids contained in food, so it is generally believed in nutrition that the amino acid pattern of food protein is closer to the amino acid pattern of human protein, the easier this protein is to be absorbed and utilized by the body, called high-quality protein. In the daily diet, foods rich in high-quality protein are: dairy, eggs, livestock meat, fish and shrimp and plant-based foods in dairy and its products.
, experts recommend that in the special period of epidemic prevention and control, ensuring adequate intake of dietary protein, especially high-quality protein intake, is an important dietary principle to enhance the body's immunity against viral infection.
