Pure milk is rich in nutrition, and the chemical composition of milk is very rich in minerals. Besides the familiar calcium, there are many elements such as phosphorus, iron, zinc, copper, manganese and molybdenum. The most rare thing is that milk is the best source of calcium for human body, and the ratio of calcium to phosphorus is very suitable, which is beneficial to the absorption of calcium. Complex, with at least 100 species. The main components are water, fat, phospholipids, protein, lactose and inorganic salts. The main chemical components of ordinary milk are:
Humidity: 87.5%
Fat: 3.5%
Protein: 3.4%
Lactose: 4.6%
Inorganic salt: 0.7%
There are 20 kinds of amino acids that make up human protein, 8 of which are not synthesized by human body. These amino acids are called essential amino acids. If the protein we eat contains all the essential amino acids, this protein is called total protein. Protein in milk is whole protein.
Inorganic salts in milk are also called minerals. Milk contains cations such as Ca2+, Mg2+, K+ and Fe3+ and anions such as PO43-, SO42- and Cl-. In addition, there are trace elements I, Cu, Zn, Mn and so on. Most of these elements play an important role in human development, growth and metabolic regulation. Calcium is the most abundant inorganic salt in human body and the main component of bones and teeth. 90% of calcium in human body is concentrated in teeth and bones. Children and adolescents need adequate calcium for their growth and development, as do pregnant women, adults and middle-aged and elderly people. Calcium deficiency will affect the normal development of teeth and bones, leading to rickets. Calcium in nature exists in a bound state. Only when it is passively absorbed by plants to form bioactive calcium can it be better absorbed and utilized by human body. Milk is rich in active calcium, which is one of the best sources of calcium in human body. 1 l fresh milk contains about1250mg of active calcium, ranking first among many foods, which is about 10 1 times of rice, 75 times of lean beef and10/0 times of lean pork. Good absorption is especially critical for calcium supplementation. Therefore, the saying that "milk can supplement calcium" has its scientific reason.
For middle-aged and elderly people, milk also has a great advantage, that is, compared with the high cholesterol of many animal proteins, the cholesterol content in milk is lower (milk:13mg/100g; Lean meat: 77 mg/100 g). It is worth mentioning that some ingredients in milk can also inhibit the amount of cholesterol produced by the liver, so milk can also lower cholesterol.
But the nutritional value of soybean milk is easier to absorb. Fresh soybean milk can be drunk all year round. Drink soybean milk in spring and autumn, nourish yin and moisten dryness, and reconcile yin and yang; Drink soybean milk in summer, relieve summer heat and heatstroke, promote fluid production and quench thirst; Drink soybean milk in winter, dispel cold and warm stomach, nourish and strengthen. In fact, in addition to traditional soybean milk, there are many kinds of soybean milk, such as red dates, medlar, mung beans, lilies and so on.
Soybean milk is rich in vegetable protein, phospholipids, vitamin B 1, B2, nicotinic acid, iron, calcium and other minerals, especially iron, which is richer than any other milk. Soybean milk is an ideal food to prevent and treat hyperlipidemia, hypertension and arteriosclerosis. Drinking more fresh soybean milk can prevent Alzheimer's disease and asthma. Soybean milk is more effective than milk in the recovery of anemia patients. Drinking hot soybean milk to supplement plant protein can enhance people's disease resistance, regulate the endocrine system of middle-aged and elderly women, relieve and improve menopausal symptoms, delay aging, reduce the occurrence of facial acne and acne in adolescent women, and make the skin white and moist.
1, fitness. Every100g of soybean milk contains protein 4.5g, fat1.8g, carbohydrate1.5g, phosphorus 4.5g, iron 2.5g, calcium 2.5g, vitamins and riboflavin. It is of great benefit to enhance physical fitness.
2. Prevent diabetes. Soybean milk contains a lot of cellulose, which can effectively prevent excessive absorption of sugar and reduce sugar, thus preventing diabetes. It is an essential good food for diabetic patients.
3. Prevention and treatment of hypertension. Soybean sterol, potassium and magnesium contained in soybean milk are powerful salt-resistant substances. Sodium is one of the main sources of hypertension. If the amount of sodium can be properly controlled in the body, it can not only prevent and treat hypertension, but also treat hypertension.
4. Prevention and treatment of coronary heart disease. Soysterol, potassium, magnesium and calcium contained in soybean milk can enhance cardiovascular excitement, improve cardiovascular nutrition, lower cholesterol, promote blood flow and prevent vasospasm. If you can insist on drinking a bowl of soybean milk every day, the recurrence rate of coronary heart disease can be reduced by 50%.
5. Prevent stroke. Magnesium and calcium contained in soybean milk can obviously reduce cerebral blood lipid and improve cerebral blood flow, thus effectively preventing cerebral infarction and cerebral hemorrhage. Lecithin contained in soybean milk can also reduce the death of brain cells and improve brain function.
6. Prevention and treatment of cancer. Protein, selenium, molybdenum, etc. Soybean milk has strong cancer inhibition and treatment ability, especially for gastric cancer, intestinal cancer and breast cancer. According to the survey, people who don't drink soy milk are 50% more likely to get cancer than those who drink soy milk regularly.
7. Prevent bronchitis. Methionine contained in soybean milk can also prevent smooth muscle spasm of bronchitis, thus reducing and relieving the attack of bronchitis.
8. Prevent aging. Selenium, vitamins E and C contained in soybean milk have great antioxidant effect, which can make human cells "rejuvenate", especially for brain cells.
9. Prevent senile stagnation, AIDS, constipation and obesity.
