The closest food to perfection-milk

Milk is called completely nutritious food, and its nutritional value can be almost completely digested and absorbed without waste.

Protein (content: about 3. 1%): contains all amino acids necessary for human body.

Fat (about 3.4%-3.8%): Milk fat is an edible fat with high digestibility and can provide energy for the body.

Lactose (about 4.7%): Almost all carbohydrates in milk are lactose, which is very important for infants' intellectual development. The absorption of calcium by human body is directly proportional to the amount of lactose. Therefore, drinking milk often can prevent rickets.

Minerals: Minerals are an important component of the body, which can maintain the osmotic pressure inside and outside the cell together with protein, and can also regulate the excitability of neuromuscular. Milk is rich in minerals, mainly including calcium, phosphorus, potassium, sodium and iron.

Vitamins: Milk contains all known vitamins.

Drinking milk is good for losing weight.

A new study points out that girls with the highest calcium intake weigh less than girls with lower calcium intake, regardless of whether their calcium intake comes from dairy products or supplements. Previous studies on animals, adults and children have also achieved similar results, but this is the first time that such results have been obtained from the study on girls. These findings support the view that calcium (especially from dairy products) helps to control weight and fat.

Researchers at the University of Hawaii studied 323 girls aged 9~ 14, and collected data on what these girls ate and how much they exercised. They also measured the girl's weight and body fat near her navel and above her hip bones. This so-called "skinfold thickness" measures abdominal fat. Naturally, girls who consume the most calories and exercise the least weigh more and have more body fat. However, after checking their calcium intake, the researchers found that girls with more calcium intake weigh less than girls with less calcium intake, although their calorie intake and exercise amount are different.

In fact, the investigators found that as long as you drink an extra glass of milk or eat a small piece of cheese (containing about 300 mg of calcium) every day, you can reduce abdominal fat 1.3 cm and lose nearly one kilogram. The researchers said that there is reason to believe that boys will have the same result. In the past few decades, the consumption of dairy products in the United States has been declining. This may explain why the number of obese people in America remains high. Therefore, people should be encouraged to add more dairy products to their daily diet, which will help them control their weight by changing their lifestyle.

This study provides exciting results, that is, the effect of eating more calcium or dairy products on human body composition, especially fat quality. The results further prove that high calcium intake may play a very important role in solving the increasingly serious obesity problem in today's society, especially in children.

Dairy products and dental care

1. A large amount of calcium in milk and its products can promote the normal development of teeth and is of great benefit to dental health.

2. Fluorine in milk and its products can promote the formation of tooth enamel, inhibit or slow down the production of some acid-causing factors that lead to dental caries, and promote the remineralization of teeth damaged by acid factors. At the same time, fluorine can also replace the hydroxyl in hydroxyapatite, an important mineral salt in teeth, to form another kind of fluorapatite with special resistance to dental caries, thus improving the dental caries prevention ability.

3. Fat and protein in milk and its products also play a special role in dental care. A special phosphorus-containing compound in milk fat can form a thick active protective film on the tooth surface, which can effectively inhibit the damage of harmful bacteria and other erosion factors in the mouth to the tooth surface. 4. Casein (or casein), which accounts for about 2.4% of milk components, can play a special role in preventing caries by adsorbing the tooth surface. This is because casein molecules in milk and its products can closely combine with enamel, the main component of teeth, reducing its solubility, thus protecting teeth and preventing teeth from being invaded by bacteria that can corrode teeth in sugary foods. In addition, if the enamel of teeth is not damaged, calcium and phosphate ions in protein molecules can also help them to repair and heal.

Japanese experts recently found that yogurt contains a biochemical active substance called vitamin L2, which has obvious effects of preventing tooth decay and promoting milk secretion. At present, Japanese experts are planning to make a new healthy food that can prevent tooth decay and promote milk secretion by using this vitamin L2 extract in yogurt.

6. According to recent medical reports, a recent study by Professor John Hargreaves, a famous dental expert from Albert University in the United States, shows that cheese, a fermented dairy product, not only has high nutritional value, but also has obvious special medical and health care functions to prevent tooth decay. In his research, the professor found that if people can eat a piece of cheese the size of cube sugar after meals, they can effectively prevent tooth decay, which is a common dental disease and affects human health. Professor John Hargreaves and his partners made a long-lasting and detailed analysis, pointing out that cheese can effectively prevent tooth decay, mainly because the mineral calcium and its phosphate in cheese can be fully mixed with saliva in the mouth, and this mixture can stay on the surface of teeth for more than two hours, thus protecting teeth from acid corrosion caused by eating sweets or drinking sugary drinks. 7. According to relevant literature, American dentists found that teeth preserved with milk are an important prerequisite to ensure the success of replantation. Experts believe that this is mainly because milk can prevent teeth from drying, maintain the activity of periodontal ligament and have more permeability for teeth, so the survival rate of tooth replantation with milk wetting is the highest. In addition, further pathological studies also show that the tooth surface absorption area and inflammatory reaction of replanted teeth preserved with milk are the least.

Supplementing nutrition to help sleep

Supplementing nutrition in summer, many people often have no appetite because of the hot weather, especially children, who are prone to anorexia. At this time, you can drink more milk to supplement the nutrition your body needs. According to Ms. Du, a nutrition expert in Qianfoshan Hospital, milk contains many kinds of nutrients needed by human body, such as protein, fat, carbohydrates, calcium, iron, zinc, selenium and other trace elements, as well as vitamins A and B. In addition, the data show that people sweat a lot in summer, which leads to calcium loss in the body. Drinking milk is a good way for people to supplement calcium.

Regulating gastrointestinal function In addition, the carbohydrate in milk is mainly lactose. Lactose can regulate gastric acid, promote gastrointestinal peristalsis and digestive gland secretion, promote the reproduction of lactic acid bacteria, inhibit the growth of pathogenic bacteria and spoilage bacteria, and be beneficial to the activity and reproduction of normal intestinal flora.

Improve the quality of sleep. It is hot every day in summer, and sometimes I can't sleep well at night. At this time, you can drink a cup of warm milk with honey before going to bed, which can make people fall asleep safely and improve the sleep quality of insomniacs obviously.

Can drinking milk get angry in summer?

Some people think that the winter temperature is low, the human body's metabolism is slow, and the essence is sealed, which is suitable for drinking milk. The temperature is high in summer, people sweat a lot, and drinking milk is easy to be hot and dry. In fact, this statement is completely unfounded. Chinese medicine believes that milk is sweet and slightly cold, which has the functions of moistening lung and strengthening stomach, moistening intestine and relaxing bowels, and tonifying deficiency, indicating that drinking milk will not cause dryness and heat. Although the summer climate is hot and people sweat a lot, the water in milk accounts for 70% to 80%, and protein and fat are easy to digest and absorb, which shows that drinking milk in summer is beneficial.

Pay attention to food hygiene when drinking milk in summer.

See clearly that the shelf life of milk has passed the shelf life, bacteria will multiply rapidly in hot days, and symptoms such as diarrhea will appear after drinking.

Don't drink every meal. It is very hot in summer. After milk is opened and left for a long time, bacteria will multiply in large numbers. So we must pay attention to food hygiene, and it is best to drink and cook as much as possible. Not suitable for use after cooking.

Anti-long-term illumination In summer, if the packaging materials can't effectively shade the light, the vitamins in milk will be greatly damaged after long-term illumination.

Do you want hot milk in summer?

It is reported that the milk we buy in bags or boxes is sterilized. Although food goes bad easily in summer, as long as the milk we buy is within the shelf life and stored reasonably, it can be directly opened for drinking without heating. If the milk has gone bad, you can't drink it any more, and heating won't help; If some milk is put in the refrigerator, and the drinker's stomach is afraid of being cold, it is best to warm the milk a little, or put it for a while, and then drink it when the temperature of the milk rises. Excessive heating of milk will destroy its nutrients.

Milk or yogurt?

According to Ms. Du, fresh milk and yogurt have little difference in protein, fat, vitamins and other nutrients, and they can replace each other in this respect. The difference between the two is that:

Protein and fat of yogurt are more easily absorbed by human body, and the utilization rate of calcium, phosphorus and iron is also greatly improved. Lactic acid bacteria in yogurt produce organic acids such as lactic acid, which effectively reduces the pH of the intestine, thus effectively inhibiting the reproduction of harmful bacteria in the intestine. Yogurt can increase intestinal beneficial bacteria and maintain the balance of intestinal flora. Yogurt can also promote the secretion of saliva and gastric juice, increase appetite, enhance gastrointestinal digestive function, and treat adolescent constipation and dyspepsia.

But yogurt can't be heated, while milk can be heated. It is more suitable for some people who are afraid of cold stomach to drink fresh milk. Yogurt has a high sugar content and is not suitable for fat people and people who are losing weight. According to the technical staff of Jiabao Company, one or two-year-old children have poor gastrointestinal development, and some are not suitable for drinking yogurt, so it is better to drink milk. In addition, the acidic substances of yogurt are easy to corrode teeth, so you should pay attention to gargle after drinking.

Can fruit yogurt replace milk?

Fruit yogurt is actually a kind of beverage fermented by lactic acid bacteria, which is deeply loved by children. However, experts pointed out that lactic acid bacteria drinks can not replace milk or yogurt, because the milk content of lactic acid bacteria drinks on the market at present is generally only 30% or lower, and the same amount of lactic acid bacteria drinks only contain 1/3 milk at most.

Precautions for special people

According to Ms. Du, some special people should choose special varieties when drinking milk:

Lactose is an important component of milk. Some people who lack lactase in the intestine will have symptoms such as flatulence and diarrhea after drinking milk because they can't decompose lactose well. These people need lactose-free milk.

Patients with cholecystitis and pancreatitis limit their fat intake and can only drink low-fat milk.

People with hyperlipidemia and coronary heart disease can only choose low-fat milk.

"Human Nanny"-Milk

Xu mingzhen

Health comes from balanced nutrition, and milk contains comprehensive, rich and balanced nutrients, which is beyond the reach of other foods. Milk includes human milk, milk, goat milk, horse milk and so on. You usually eat more milk. In terms of absorption and utilization rate, milk is the closest to human milk, similar to eggs. But cows are mammals, and people are mammals. Alpo, the father of medicine, said that milk is the most ideal food, but human nannies have scientific basis.

First, milk contains about 3.5% protein and 3.5% fat. In protein, casein is the main component, accounting for 86%, followed by milk protein and lactoglobulin, all of which contain all essential amino acids needed by human body, and its protein digestibility is higher than that of other animal proteins, reaching 98%. Low melting point oleic acid accounts for 33% in milk, which contains essential fatty acids and lecithin. Fat globules are extremely small and highly dispersed, which are easy to digest and absorb.

Second, milk is rich in calcium, which is the best source of calcium supplementation. The calcium content of milk is about 1000- 1 100 mg/kg. Because it is organic calcium, it is easy to digest and absorb when combined with protein, and the absorption rate is as high as 70%, while the average food is only 20%-30%. People in China are generally short of calcium, children suffer from retention and dental caries due to calcium deficiency, and middle-aged and elderly people suffer from osteoporosis due to calcium deficiency. There are 30 million fracture patients in China every year. Nutrition survey data show that the daily calcium intake of all kinds of people in China only accounts for half of the supply. And 70% of the daily calcium intake of Americans comes from milk.

Milk is not only nutritious, but also cheap. Today, for health, people of all ages should insist on drinking milk every day. Because teenagers are an important period of growth, although the physique of adults no longer grows, human tissues and organs need to be constantly updated, such as protein in the liver and calcium in the bones. Adults shoulder the heavy responsibility of society and family. As the body changes from vigorous to stable and then to recession, the ability of the elderly to absorb and utilize nutrition declines. Therefore, drinking milk can provide sufficient nutrition, satisfy growth and delay the aging process. If you drink a box (bag) of 250g sterilized milk in the morning and a cup of 200g yogurt in the afternoon, you can provide 540mg of calcium and 15g of high-quality protein every day, meeting 50% of the calcium and essential amino acids needed by human body.

Thirdly, milk also contains zinc, copper, manganese, carbohydrates and various known vitamins (A, B, D, etc. ), especially milk contains more vitamin A and vitamin B2, which are not found in general foods. There are more alkaline elements (calcium, potassium, sodium) in milk than acidic elements (chlorine, sulfur, phosphorus), which is an alkaline food and contributes to.

Milk also has medical and health care value, such as preventing stomach acid and treating gastric ulcer. An island in Japan is a high incidence area of gastric cancer, but the incidence of gastric cancer is greatly reduced because the residents who immigrated to the United States drank more milk in the United States. Scientists at Harvard University have found that eating more red meat (cattle, sheep and pork) is more likely to develop colon cancer, but eating milk that usually contains high animal fat will not increase the risk of this disease.

Milk contains less cholesterol, and also contains 3- hydroxymethylglutaric acid and orotic acid which can lower blood cholesterol. Yogurt is milk fermented with lactic acid bacteria. Contains Bifidobacterium and Streptococcus thermophilus. Lactobacillus bulgaricus has three beneficial activities, which can prevent and treat constipation, diarrhea and abdominal pain. At the same time, active lactic acid bacteria produce active antibody substances in the intestine to improve immunity; It also produces special TEB acid substances to play an anti-cancer role and convert lactose into glucose and lactic acid, which is beneficial to absorption and appetite promotion. In addition, yogurt can also reduce the side effects of antibiotics. For some people who lack lactase in the intestine and feel unwell when drinking milk, they should drink yogurt instead.

People in the Caucasus of the former Soviet Union, a world-famous longevity area, have the habit of drinking yogurt. In Europe, children's milk is highly valued, and most of them are provided free of charge or at half price. The health care effects of milk are widely publicized, such as printing milk on the packaging box to make you smart, help you study and exercise, and improve your abstract thinking ability. In Japan, which was extremely poor after the war in the 1940s, the aided milk powder was used for school children's lunch. This measure protected a generation of children from hunger and malnutrition, made the postwar generation physically strong, surpassed their predecessors, and provoked the burden of economic take-off. "A glass of milk makes a country strong" is no exaggeration. At present, the annual per capita milk quantity in the world is 105 kg, while that in China is less than 6 kg. In order to make our motherland stronger tomorrow, we will carry out the milk revolution.

Because milk is nutritious, it is also the best culture medium for bacteria. In order to prevent human-to-human transmission and the spread of infectious diseases by people and animals, the state promulgated the Measures for the Hygienic Management of Dairy Products and related hygienic standards. It is clearly stipulated that cows should be vaccinated and quarantined one by one every year, and sick and healthy cows should be grouped. Sick milk, spoiled milk. Milk is not allowed to be eaten during antibiotic injection and within 5 days after drug withdrawal. Raw milk needs to be refrigerated and can be further processed into sterilized milk or yogurt after inspection. In particular, fresh milk (mainly bulk milk) is prohibited from being sold on the market. Because raw milk is not effectively disinfected and its packaging is not standardized, it is easy to spread human and animal infectious diseases, adulteration or adding some substances to cover up the deteriorated milk, which is harmful to health. In addition to not buying raw milk, we should also pay attention to whether the milk packaging is complete and tight, whether the consumption period has passed, whether the milk that needs to be refrigerated at 4℃ has refrigeration sales facilities, whether the main ingredients are consistent with the product name, whether it meets the national regulations on dairy products, and whether the production enterprise has a specific name and address.

Nutritional characteristics of milk

Sina diet in August 2003

(1) protein in milk contains eight essential amino acids, which are suitable for forming muscle tissue and promoting healthy development. It is more important for children and adolescents in the growth and development stage.

(2) The fat contained in milk has a low melting point and small particles, and is easily digested and absorbed by human body, with a digestibility of 97%.

(3) The main carbohydrate in milk is lactose, which can regulate gastric acid, promote intestinal peristalsis and help the secretion of digestive glands in human body.

(4) Calcium contained in milk is the best source of calcium for human body. Because the calcium in milk is easily absorbed by human body, which is much higher than other kinds of food. Moreover, the proportion of calcium and phosphorus in milk is appropriate, which is an ideal nutritious food to promote the development of bones and teeth of children and adolescents.

(5) Milk contains almost all known vitamins, such as vitamin A, vitamin C, vitamin D and B vitamins.

(6) Milk also contains antibody substances needed to promote children's development. Milk is the most ideal food for the healthy growth of children and adolescents. After World War II, Japan put forward the slogan "A glass of milk makes a nation strong". There is also a famous saying in Britain: "Nothing is more important than providing milk to children!" Therefore, 12 famous scientists in the fields of nutrition, food and dairy industry in China called for the revitalization of china dairy in "1998 China Dairy Science Forum" and often gave children milk.
