The benefits of drinking milk often
1, beauty and skin care
The benefits of drinking milk every day are first reflected in beauty and skin care. Legend has it that in ancient Rome, Cleopatra often used milk to beautify herself. Besides drinking milk every day, she often bathes herself in milk, thus having a silky skin.
2. Prevention of Alzheimer's disease
According to expert survey, with the increasing intake of milk and other dairy products, the incidence of Alzheimer's disease (a kind of Alzheimer's disease) has a downward trend, and vascular dementia also shows similar results. Similarly, the research of Professor Hidehiko from Central University also found that lactic acid bacteria drinks can improve short-term memory and attention.
A survey of 249 participants by professors from Tokai Gakuen University in Japan shows that those who drink more milk are less anxious than those who drink less, and tend to go to bed early and get up early, while those who drink less take a long time to fall asleep and have poor sleep quality. There is a direct correlation between poor sleep quality and cognitive impairment, and the researchers infer that this may be the reason why drinking milk can indirectly prevent cognitive impairment.
China and the United States believe that this is mainly due to the role of tryptophan contained in milk. On behalf of Japan's sleep evaluation research institute, Shirakawa Hideyoshi, MD, quoted research data as saying that tryptophan in milk exists in the form of casein, and its content is not much, so it is meaningless to drink only one cup before going to bed; If you want to improve your sleep and prevent cognitive impairment by drinking milk, you need to get into the habit of drinking it every day and stick to it for a while before it can be effective. However, domestic experts suggest that milk should be warmed after cold storage, which can prevent low temperature from affecting the function of lactose decomposing enzymes in human body, and reduce the stimulation of cold milk to the stomach and avoid discomfort.
The disadvantages of drinking milk often
Lead to excessive intake of protein and damage to health; Milk is acidic, which will dissolve calcium and lead to osteoporosis; Leading to an increase in the risk of diabetes and skin allergies; Leading to an increase in the risk of cancer such as breast cancer.
Taboos for drinking milk
1, dairy products may also help you lose weight.
Low-fat dairy products are the best snacks, because they contain not only carbohydrates, but also protein.
"Dairy products are not only the best snacks for diabetics, but also the best snacks for anyone else. Because dairy products can keep your blood sugar level. " BonnieTaub—Dix MARD, spokesman for the American Nutrition Society, said.
2, milk should not be eaten raw, be sure to boil and drink.
Milk may be contaminated by harmful bacteria such as mycobacterium tuberculosis and Shigella dysenteriae in all aspects of production and transportation. Pasteurization is widely used in bagged milk in the market, but its instantaneous sterilization may not be complete, and the residual bacteria will continue to multiply at a suitable temperature to cause diarrhea and other symptoms, so milk must be boiled before drinking.
3. It is best to use indirect heating method for milk, but the boiling time should not be too long.
Direct heating will lead to protein coagulation of milk, and if it is boiled for too long, the calcium phosphate in it will change from acidic to neutral and precipitate, and lactose will be decomposed into lactic acid and formic acid due to coking, thus reducing the nutritional value, color, aroma and taste of milk.
4. It is not advisable to add brown sugar when drinking milk.
Oxalic acid in brown sugar will denature milk protein, cause digestive dysfunction, and even hinder the absorption of trace elements such as iron, resulting in "milk anemia". So don't add brown sugar when drinking milk, but you can add some white sugar or rock sugar to taste.
5, drinking milk can not be on an empty stomach, it is best to eat with some starchy foods.
Fast gastrointestinal peristalsis on an empty stomach greatly shortens the retention time of milk in the stomach, which is not conducive to nutrient digestion and absorption. If you drink milk and eat some starchy foods such as steamed bread and bread, you can help the human body fully absorb the rich nutrition of milk. Of course, choosing to use milk after meals will have the same effect.
Don't drink milk directly in big gulps. When you chew it or sip it with a spoon, milk will directly contact with gastric acid to form acid protein clot, which may cause diarrhea and bloating to people with weak stomach and intestines. Chewing slowly will help to neutralize saliva and milk and help the human body digest and absorb nutrients.
Common sense of drinking milk every day
1. How much milk should each person drink every day?
As a kind of food with high nutritional value, it is difficult to play its due role if it is drunk less, and it is difficult to digest, absorb and utilize if it is drunk more. The daily milk consumption should be determined according to age, work consumption and economic conditions.
Generally speaking, adults should drink 400 ~ 500ml, that is, two bottles (two bags) of milk a day, but at least 250ml, that is, one bottle (one bag) of milk. Economic conditions permit the best three bottles (three bags), that is, about 750 ml, but it is best not to exceed 1000 ml. Simply put, it is "guarantee one bottle and strive for two bottles, preferably three bottles and no more than four bottles."
Second, when is it good to drink milk?
Milk is a basic food for people, and it is generally advisable to drink it after meals for three meals a day.
It is better to drink one bottle a day for breakfast, and two bottles a day for morning and evening. You can also drink it outside three meals according to your personal living habits, but you should pay attention to eating starch-rich food before drinking, so that milk can stay in the stomach for a long time, which is conducive to the comprehensive absorption and utilization of nutrients.
This is the reason why it is not advisable to feed on an empty stomach. "Morning, noon and evening will do, and it is best to drink after meals.
Third, what should I do if I drink milk?
"Add it slowly from less to more, and it is best to drink yogurt instead. Some people are not used to drinking milk, and their bodies are not adapted. After drinking milk, they often have abdominal distension, slight abdominal pain and diarrhea, which is a kind of lactose intolerance, and there are more people with lactose intolerance in Asia.
Ways to overcome it: First, we can gradually increase the milk consumption from less to more, so as to induce the production of lactose decomposing enzymes and adapt slowly; Second, you can drink yogurt instead, because most lactose has been decomposed after yogurt is fermented by lactic acid bacteria. It can be said that yogurt is a dairy product more suitable for orientals to drink.
Can drinking milk at night help you sleep?
According to medical experts in the United States and Britain, milk contains a "natural sleep factor" called α-lactalbumin, which has the function of regulating brain nerves and improving sleep.
Therefore, experts suggest drinking a glass of milk in the evening or half an hour before going to bed, which has a calming effect and can promote sleep.

"A glass of milk before going to bed makes you fall asleep quickly.
Five, drink yogurt?
Yogurt is a dairy product with special flavor after ordinary milk is fermented by lactic acid bacteria. It can increase some vitamins and bioactive substances, and its nutritional components are more perfect than milk, which is more conducive to digestion and absorption.
The live lactic acid bacteria in yogurt can also promote the harmonious balance of human intestinal flora and the excretion of toxic and harmful substances, which has certain disease prevention and health care functions. Some people call it "intestinal scavenger", while others describe it as "sour, sweet and first love-like feeling.
However, it should be noted that it should not be heated before drinking, should not be taken at the same time with antibiotics, and should not be fed to babies.
Is it really best to drink milk to supplement calcium?
Milk not only provides high-quality protein, fat, vitamins and other nutrients for human body, but also is rich in natural milk calcium. The proportion of calcium and phosphorus is appropriate, which is beneficial to digestion and absorption. It is recognized as the best calcium source, which is more economical and effective than taking calcium supplements.
According to scientific calculation, drinking 2-3 bottles of milk every day, plus a normal diet, can basically meet the human body's demand for calcium. Experts say that normal people need 800-900 mg of calcium every day, normal food provides about 400mg, and about 400 mg is best supplemented by drinking milk. "To get good legs and feet, drink more milk every day. However, it should be noted that it is not suitable to eat with vegetables (spinach, etc.) with more oxalic acid, fruits (persimmons, etc.) with more tannic acid and strong tea.
Which is better to drink milk, soy milk or soy milk?
Milk provides animal protein, while soybean milk provides plant protein, and the contents of minerals and vitamins are also different, while soybean milk usually adds about 5% milk powder or 30% milk to soybean milk.
They are nutritionally complementary, but they cannot be completely replaced. Therefore, according to your own eating habits and conditions, you can give priority to milk and drink it reasonably in order to obtain more balanced nutrition.
Does drinking milk have a protective effect on the stomach?
Because milk can form a good protective layer on the surface of gastric mucosa, it can alleviate the erosion of gastric mucosa by irritating foods such as alcohol and reduce the occurrence of stomach diseases. Japan has long reported that the incidence of gastric cancer is low among milk drinkers.
Rumours of milk
The thicker the milk, the better?
Some new parents are always afraid that fresh milk is too weak and lack of nutrients when feeding their babies, so they add milk powder to it. But this move is harmful and not beneficial.
In fact, the organs of infants and young children are delicate, and the excessive burden and pressure may be fatal. Therefore, the shade of milk should be directly proportional to the age of the child. Even for newborns who are thought to be a month old, the proportion of water seepage in milk should be gradually reduced according to the digestion situation.
If infants often eat thick milk, it will cause diarrhea, constipation, loss of appetite, and even refusal to eat. Over time, weight will not increase, but also cause acute bleeding enteritis, and the consequences are unimaginable.
Can milk be boiled?
Milk is the most common "healthy companion" in life, but many people often worry about the disinfection of milk while drinking it, and often take cooking until it boils. In fact, the temperature requirement of milk disinfection is not high, 3 minutes at 70 degrees Celsius and 6 minutes at 60 degrees Celsius.
If boiled, the lactose in milk will be coked, while caramel can induce cancer. Furthermore, after boiling, calcium in milk will precipitate with phosphoric acid, thus reducing the nutritional value of milk.
Is it good to send milk to take medicine?
In the modern life where efficiency is paramount, many things that kill two birds with one stone are often associated with milk, but there are many extreme mistakes that must be corrected. For example, we are going to talk about using nutritious milk and taking medicine, which most people take for granted.
Milk can obviously affect the absorption rate of drugs in human body, so that the concentration of drugs in blood is greatly reduced compared with that of non-milk drug users in the same time. Taking medicine with milk is also easy to form a covering film on the surface of the medicine, so that mineral ions such as calcium and magnesium in milk react with the medicine to generate water-insoluble substances, which not only reduces the curative effect, but also may cause harm to the body.
Milk's "enemy"
VD
Milk calcium is an important source of calcium. Some parents know from advertisements that calcium supplementation needs vitamin D, and more sunshine is a good way to absorb vitamin D, so they put bottled milk in the sun according to the prescription.
