Taboo to drink milk, milk is a very common drink in daily life. Milk not only tastes delicious, but also has many special benefits to human body. But milk can't be drunk blindly. Let me introduce the taboos of drinking milk in detail. Come and have a look!
Taboos to drink milk 1 1, milk can't be drunk on an empty stomach.
Many people firmly believe that drinking milk on an empty stomach can't absorb the nutrition. However, one-year-old or two-year-old babies take milk as their staple food. No one has heard that babies should drink half a bowl of rice porridge before drinking milk, so with the digestive ability of healthy adults, even drinking milk before meals can be well digested and absorbed. The fact is that drinking a glass of milk can effectively relieve hunger for more than an hour.
Some people say that drinking milk on an empty stomach will cause waste in protein. In fact, not eating staple food and eating a lot of fish and meat at banquets is a waste in protein, and milk contains about 4.6% lactose, which belongs to carbohydrates and will give priority to energy supply and save protein; In addition, milk also contains about 3% fat, which also plays a role in supplying energy. Therefore, drinking milk on an empty stomach will not cause waste in protein.
Poor digestion is best to drink yogurt.
It should be noted that if there is abdominal distension and diarrhea after drinking milk, it means that the body's lactose digestion ability is poor, or there are symptoms of lactose intolerance, so it is really not appropriate to drink milk on an empty stomach. It is recommended to eat starchy food first, and then drink milk in small quantities many times, preferably yogurt. Besides, after getting up in the morning, you should drink a cup of boiled water first, and then drink milk 20 minutes later.
2. Milk can't be drunk with juice.
It is a normal phenomenon that casein in milk will precipitate when it meets weak acid. Therefore, some people think that milk precipitation loses its nutritional value or cannot be absorbed by the human body. But think about it, the acidity of human stomach acid is much stronger than that of fruit juice, so even without fruit juice, milk will form precipitation in the stomach. In addition, yogurt fermented by lactic acid bacteria is also in a precipitated state. All kinds of desserts made of milk and fruit are also very popular abroad, and I have never heard of digestive problems in Europe and America. If the gastrointestinal function is normal and you don't feel diarrhea and bloating when drinking cold milk, then you don't have to worry that drinking juice immediately after drinking milk will cause trouble.
3。 Milk can't be drunk with sugar.
Some people think that adding sugar to milk will affect the digestion and absorption of milk. However, most milk powder products are sugared products, and consumers in various countries have been drinking sugared milk powder for more than a hundred years. Traditionally, Chinese consumers like to drink sugared milk, and there is no report of indigestion caused by adding sugar.
On the contrary, if you drink it when you are hungry, the nutrient source of milk energy supply can be more rationalized after adding sugar.
Browning reaction is not "harmful"
Others say that boiling milk with sugar may produce "fructosyl lysine", which has certain toxicity. This formulation is not accurate.
In fact, the reaction rate of lactose and lysine contained in milk at high temperature is higher than that of sucrose and lysine. This reaction is called Maillard reaction, which is the same as the browning of bread crust after baking. Although this browning reaction will cause a small amount of lysine loss, it is not harmful at all.
4, milk must be heated to drink.
Many people think that milk must be heated, even if it is sterilized milk, it should be boiled in a pot before drinking. In fact, the "milk scale" stuck to the pot after boiling milk contains a lot of calcium, which causes serious nutritional loss. Sterilized milk can be drunk directly without heating within the shelf life after ultra-high temperature sterilization.
For those with cold stomach, excessive peristalsis of intestine after drinking cold milk may cause mild diarrhea. You may wish to use microwave oven or hot water to heat sterilized milk until it feels a little hot before drinking.
5. Only high calcium milk can supplement calcium.
The calcium content of so-called "high calcium milk" is only 130 ~150mg/100ml, while the calcium content of ordinary milk can reach110mg/100ml, and some products can even reach.
Compared with ordinary milk, "high calcium milk" has no obvious advantages. Calcium in milk is easily absorbed milk calcium, which contains lactose, amino acids, vitamin D and other absorption promoting factors, while artificially added calcium is inorganic calcium such as calcium lactate with extremely low price, and its absorption rate may not reach the level of milk calcium.
It can be seen that if you need to supplement calcium, you only need to drink milk every day, and you don't necessarily need to drink "high calcium milk".
6. Drinking milk will make you fat.
Milk contains about 86% water, and a bag of 250g full-fat milk only contains calories 150 kcal, which is equivalent to half a bowl of rice. However, eating 100 grams of biscuits will consume more than 450 kilocalories. A can of coke also contains 140 kcal, which is equivalent to a bag of whole milk. Visible, milk is not easy to make people fat food, and the milk contains rich protein, vitamins and minerals, which is incomparable to Coke.
Milk has an excellent feeling of fullness. Drinking a glass of milk before meals can effectively alleviate hunger, reduce appetite and help people not eat so much at dinner. If you use two cups of milk and cold vegetables instead of dinner, it can even help people lose weight. It should be noted that if you have the habit of drinking milk before going to bed at night, you should reduce your dinner intake accordingly to avoid getting fat by taking in extra calories.
7. The less fat in milk, the healthier it is.
The fat content in milk is only 3%. Drinking a bag of 250 grams (243 ml) of milk every day will increase the fat by 7.5 grams. For urban families, the daily intake of fat is usually more than 80 grams, and this fat in milk is not high in a day.
Low-fat milk or semi-skimmed milk contains fat1.0% ~1.5%, and whole skimmed milk contains fat 0.5%. Therefore, replacing whole milk with low-fat milk means reducing fat by 3.75 ~ 5.0 grams, and even skim milk can only reduce fat by 6.25 grams. In contrast, cooking with less oil, not eating fried food, eating less pork and going to restaurants are the major plans to reduce fat.
Vitamins A and D in milk and conjugated linoleic acid, an anticancer substance, all exist in the fat part. Aroma components also exist in milk fat. Removing fat from milk will significantly affect its nutritional value, flavor, taste and satiety. Therefore, unless there is a need to control blood lipids, it is not necessary to choose skim and low-fat milk.
Taboos to drink milk 2 1, can't eat with chocolate.
Many people like to eat chocolate in milk. Although it tastes good, it is very harmful to our health. Calcium in milk will react with oxalic acid in chocolate to produce calcium oxalate, which will affect our absorption of calcium, leading to calcium deficiency, slow development, dry hair and rough hair, and may also lead to urinary calculi.
2, can't eat with porridge.
It is often seen that people drink a bowl of porridge at breakfast and then a glass of milk, thinking that this can complement each other. In fact, this is not right. Lipoxygenase contained in porridge will destroy vitamin A contained in milk. If children eat it often, it will lead to insufficient intake of vitamin A, making infants and young children stunted and sickly.
3, can't eat with tea.
It is suggested that you drink tea one hour after drinking milk, because tannic acid in tea will hinder the absorption of calcium in milk and cause nutritional waste. So when you drink milk, you should be careful not to drink tea together.
4, can't eat with medicine.
It is incorrect to drink milk just after taking the medicine, or to take the medicine directly with milk. Milk will destroy the effective components in the medicine, which will greatly reduce the efficacy and have no effect on treating diseases.
5. Don't boil the milk
One more thing to note is that milk should not be boiled and drunk, which will destroy the nutrients in milk. Don't add sugar to it during the process of boiling milk, which will endanger your health. It is ok to add sugar after the milk is heated.
Taboo to drink milk 3 1, milk+chocolate: Some people think that since milk is a high-protein food and chocolate is an energy food, it must be beneficial to eat both at the same time. That was not the case. Adding chocolate to liquid milk will make calcium in milk react with oxalic acid in chocolate to produce "calcium oxalate". As a result, calcium, which had nutritional value, became a substance harmful to human body, which led to calcium deficiency, diarrhea, dry hair, easy fracture and increased the incidence of urinary calculi.
2. Milk+eggs: Experts pointed out that breakfast with milk and eggs is not scientific, and it is difficult for protein to provide energy. Now more than 9% people only eat milk and eggs in the morning, and food has been absent from breakfast for a long time. Most people think that this kind of breakfast is in line with international standards, but this is a very wrong concept. Milk and eggs are good things, but they are used in the wrong place. After more than ten hours of energy consumption in one night, the human body in the morning urgently needs to replenish energy by breakfast rich in carbohydrates, but milk and eggs can't provide enough energy.
3, milk+rice soup, porridge: Some people think that this can make nutrition complementary. In fact, this practice is very unscientific. Milk contains vitamin A, while rice soup and porridge are mainly starch, which contains lipoxygenase, which will destroy vitamin A. Children, especially infants and young children, if they don't take enough vitamin A, it will cause eye diseases, and it will also lead to rough skin, dry and brittle hair, easy to fall off, and many lines on nails. Therefore, even to supplement nutrition, the two should be eaten separately.
4. The thicker the milk, the better: Some people think that the thicker the milk, the more nutrients the body gets, which is unscientific. The so-called over-concentrated milk refers to adding more milk powder and less water to milk, so that the concentration of milk exceeds the normal proportion standard. Some people are afraid that fresh milk is too weak, so they add milk powder to it. If people with poor stomach function drink too much concentrated milk, it will cause diarrhea, constipation, loss of appetite and acute hemorrhagic enteritis. This is because the stomach can't bear the heavy burden and pressure.
5. Milk+orange juice or lemon juice: Some people suggest adding orange juice or lemon juice to milk, which seems to be a good way, but in fact, orange juice and lemon are fruits with high fruit acid, and when fruit acid meets protein in milk, protein will be denatured, thus reducing the nutritional value of protein.
6, milk+medicine: Some people think that it is definitely good to take medicine with nutritious things. In fact, this is extremely wrong. Milk can obviously affect the absorption rate of drugs in human body, so that the concentration of drugs in blood is obviously lower than that of non-milk users in the same time. Taking medicine with milk is also easy to make the drug show a covering film, so that mineral ions such as calcium and magnesium in milk react with the drug to generate water-insoluble substances, which not only reduces the efficacy, but also may cause harm to the body. Therefore, it is best not to drink milk for 2 hours before and after taking the medicine.
7, the more sugar, the better: milk without sugar is not easy to digest, which is the "* * * knowledge" of many people. Sugar is added to increase the calories supplied by carbohydrates, but it must be quantified, usually 5-8 grams of sugar per 100 ml of milk. What sugar should I add to the milk? Preferably sucrose. Sucrose enters the digestive tract and is decomposed by digestive juice, which becomes glucose and is absorbed by the human body. Glucose is low in sweetness, and it is easy to exceed the prescribed range when used too much.
8. Milk must be boiled: Usually, the temperature requirement for milk disinfection is not high, which takes 3 minutes at 70 degrees Celsius and 6 minutes at 60 degrees Celsius. If boiled and the temperature reaches 100℃, the lactose in milk will be coked, while caramel can induce cancer. Secondly, after boiling, calcium in milk will precipitate with phosphoric acid, thus reducing the nutritional value of milk.
