Qingdao Nestle Co., Ltd. is the largest dairy processing enterprise in Laixi, and its products are sold well both at home and abroad.
The proteins in milk are mainly casein, albumin, globulin, lactin, etc. The 20 kinds of amino acids contained therein are 8 kinds of amino acids necessary for human body, and the milk protein is a full-value protein, and its digestibility is as high as 98%. Milk fat is a high-quality fat, the best quality, its digestibility is more than 95%, and contains a large number of fat-soluble vitamins. The lactose in milk is galactose and lactose, which are the most easily digested and absorbed sugars. The minerals and trace elements in milk are in a dissolved state, and the ratio of the content of various minerals, especially calcium and phosphorus, is relatively appropriate and easily digested and absorbed.

The research team divided 34 healthy obese people into two groups and let them eat 500 calories less than usual every day. One group drank three servings of low-fat yogurt containing 1,100 milligrams of calcium every day, while the other group ate 500 milligrams of calcium tablets every day. After a period of time, the results showed that the average weight, body fat and abdominal fat loss program in the yogurt group was 22%, 61% and 81% more than the other group, respectively.
Researchers believe that the calcium in dairy products can help the body burn fat and promote the body to produce more enzymes that can degrade fat. So if you're trying to lose weight, eat at least three servings of low-fat or skim dairy products a day.

Milk contains phosphorus, which plays an important role in promoting brain development in young children.
Milk contains vitamin B2, which helps with vision.
Milk contains calcium, which can enhance the strength of bones and teeth and promote the intellectual development of young people.
Milk contains lactose, which can promote the body's absorption of calcium and iron, enhance gastrointestinal peristalsis, and promote excretion.

Therefore, if you drink milk in the morning, it will inevitably inhibit the human cerebral cortex, affecting the daytime work and study. In addition, drinking milk in the morning is not conducive to digestion and absorption, this is because the milk protein through the stomach and small intestine decomposition to form amino acids can be absorbed by the body, and the morning fasting state, the stomach, intestinal emptying is very fast, so the milk can not be digested in time to be discharged to the large intestine.

Milk and health
Title Description: In November 2000, the state through a "student drinking milk program", mainly through the distribution of specialized departments, so that students in primary and secondary schools to drink milk every day between classes. The purpose is to improve the physical fitness of young people. Why would ordinary milk become a great "magic weapon" to improve physical fitness? What are the nutrients in milk? What are its benefits to the human body? In response to these questions, we carry out some investigation and find information in order to have a comprehensive understanding of this.
Recently, I found that the number of times and frequency of drinking milk at home is getting higher and higher, I asked my parents, they said, drinking milk is good, nutritious, but also can make up for calcium. Not long ago, I saw on TV that in November 2000, the state adopted a "student drinking milk program", mainly through the distribution of specialized departments, so that students in primary and secondary schools to drink milk every day between classes. The purpose is to improve the physical fitness of young people. Why has ordinary milk become a great "magic weapon" to improve physical fitness? What are the nutrients in milk? What are its benefits to the human body? In response to these questions, the teacher suggested that we take this as the subject, to carry out some research and find information, in order to have a comprehensive understanding of this.
A, the chemical composition of milk and nutritional value
Milk's chemical composition is very complex, at least more than 100 kinds of, the main components by water, fat, phospholipids, protein, lactose, inorganic salts and other components. The main chemical composition of milk is as follows:
Moisture: 87.5%
Fat: 3.5%
Protein: 3.4%
Lactose: 4.6%
Inorganic salts: 0.7%
There are 20 kinds of amino acids that make up the human body's proteins, and among them, there are 8 kinds that the human body itself can't synthesize, which are called essential amino acids. amino acids are called essential amino acids. If the protein we eat contains all the essential amino acids, it is called a whole protein. The protein in milk is a whole protein.
The inorganic salts in milk are also called minerals. Milk contains Ca2+, Mg2+, K+, Fe3+ and other cations and PO43-, SO42-, Cl- and other anions; in addition to trace elements I, Cu, Zn, Mn and so on. Most of these elements play an important role in human development and growth and metabolic regulation. Calcium is the most abundant inorganic salt in the human body and is the main component of bones and teeth. 90% of the calcium in the human body is concentrated in the teeth and bones. Children and adolescents need sufficient calcium for their growth and development, likewise pregnant women and adults, middle-aged and elderly people, also need to supplement calcium, the lack of calcium will affect the normal development of teeth and bones, leading to rickets. Calcium in nature exists in a chemosynthetic state, and can be better absorbed and utilized by the human body only if it is absorbed by animals and plants to form biologically active calcium. Milk is rich in active calcium, is one of the best sources of calcium for human beings, 1 liter of fresh milk contains about 1,250 milligrams of active calcium, ranking first in many foods, about 101 times that of rice, 75 times that of lean beef, 110 times that of lean pork, it is not only high in content, but also lactose in milk can promote the absorption of calcium by the human body's intestinal wall, with an absorption rate of up to 98%, thereby regulating the metabolism of calcium in the body, maintaining serum calcium This regulates calcium metabolism in the body, maintains serum calcium concentration, and promotes calcification of bones. Good absorption is especially crucial for calcium supplementation. The fact that you can't get a good deal on a product is a good sign that you're not going to be able to get a good deal on it.
For middle-aged and elderly people, milk also has a major benefit, is that, compared with many animal proteins with high cholesterol, milk in the cholesterol content is low, (milk: 13 mg/100 grams; lean meat: 77 mg/100 grams). It is worth noting that certain components of milk also inhibit the amount of cholesterol made by the liver, making milk also have a cholesterol-lowering effect.
