pay attention to the seven taboos of drinking milk. As milk gradually enters thousands of households, there are various & ldquo; Taboos & rdquo; It is said that milk can’t be drunk on an empty stomach, milk can’t be drunk with fruit juice, milk can’t be drunk with sugar & hellip& hellip; There are many creeds that people can’t tell the true from the false. For example, drinking milk will make you fat, and drinking milk should be heated & hellip& hellip;
in fact, there are many & ldquo; Taboos & rdquo; There may not be sufficient scientific basis for investigation, and most of them are untenable. Here are some common & ldquo; Taboos & rdquo; Analyze them one by one.
1. Can’t milk be drunk with juice?
it is normal that casein in milk precipitates in the presence of weak acid. Therefore, some people believe that milk precipitation loses its nutritional value or cannot be absorbed by the human body. But if you think about it, the acidity of human stomach 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 with milk and fruit are also very popular abroad. I haven’t heard that Europeans and Americans have digestive problems. If the gastrointestinal function is normal and you don’t feel diarrhea and abdominal distension when drinking cold milk, you don’t have to worry that drinking juice immediately after drinking milk will cause trouble.
2. Can’t you drink milk with sugar?
some people think that sweetening milk will affect the digestion and absorption of milk. However, the vast majority of milk powder products are sweetened products. Consumers in various countries have been drinking sweetened milk powder for more than 100 years. Traditionally, Chinese consumers like to drink sweetened milk, and there are no reports of indigestion caused by sweetening.
on the contrary, if you drink it when you are hungry, the nutrient source of energy supply can be more rationalized after adding sugar to milk.
browning reaction is not & ldquo; Harmful & rdquo;
others say that boiling milk with sugar may produce & ldquo; Fructosyl lysine & rdquo;, It has certain toxicity, which 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 & ldquo; Maillard reaction;, It’s the same reason that bread crust turns brown after baking. Although this browning reaction will cause a small amount of lysine loss, it is not & ldquo; Harmful & rdquo;.
3. Can’t milk be drunk on an empty stomach?
many people firmly believe that drinking milk on an empty stomach can not absorb the nutrition. However, babies aged one or two take milk as their staple food. No one has heard that babies should drink half a bowl of rice porridge before drinking milk. With the digestive ability of healthy adults, even if they drink milk before meals, they can digest and absorb well. The fact is: drinking a glass of milk can effectively alleviate hunger for more than an hour.
some people say that drinking milk on an empty stomach will cause a waste of protein. In fact, it is a waste of protein to not eat the staple food at the banquet and eat a lot of fish and meat food. However, milk contains about 4.6% lactose, which belongs to carbohydrates and will give priority to decomposition for 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 a waste of protein.
4. It’s best to drink yogurt
. It should be noted that if there is abdominal distension and diarrhea after drinking milk, it indicates that the body’s lactose digestion ability is poor or there are symptoms of lactose intolerance. In this way, it is really not suitable to drink milk on an empty stomach. It is suggested to eat starchy food first, then drink milk a small amount many times, and it is best to drink yogurt. In addition, after getting up in the morning, you should drink a glass of boiled water and milk 20 minutes later.
5. Milk must be heated to drink?
many people think that milk must be heated. Even sterilized milk must be boiled in a pot before drinking. After boiling, the milk actually sticks to the pot; Milk scale & rdquo; It contains a lot of calcium, resulting in serious nutritional loss. After ultra-high temperature sterilization, sterilized milk can be drunk directly without heating within the shelf life.
for those with cold intestines and stomach, stimulating excessive peristalsis of intestines after drinking cold milk may cause mild diarrhea. You might as well heat the sterilized milk with microwave oven or hot water until your hands feel a little hot before drinking.
6. Only high calcium milk can supplement calcium?
so called & ldquo; High calcium milk &; The calcium content of milk is only 130 ~ 150 mg / 100 ml, while the calcium content of ordinary milk can reach more than 110 mg / 100 ml, and some products can even reach 130 mg / 100 ml, & ldquo; High calcium milk &; Compared with ordinary milk, it has no obvious advantages. Calcium in milk is milk calcium that is easily absorbed. There are many absorption promoting factors such as lactose, amino acids and vitamin D. the artificially added calcium is inorganic calcium such as calcium lactate, which is very cheap, 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, not necessarily special & ldquo; High calcium milk & rdquo;.
7. Will you get fat after drinking milk?
milk contains about 86% moisture. A 250g bag of full fat milk contains only 150 kcal of heat, equivalent to less than half a bowl of rice. However, eating 100 grams of biscuits will consume more than 450 kcal of calories. A can of coke also contains 140 kcal of calories, which is equivalent to a bag of whole milk. It can be seen that milk is not an easy food to make people fat, and the abundance of protein, vitamins and minerals contained in milk is unmatched by coke.
milk has an excellent sense of satiety. 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 the human body lose weight. It should be noted that if you have the habit of drinking milk before going to bed at night, you should correspondingly reduce the amount of dinner to avoid getting fat due to additional calories.
