Why not drink milk on an empty stomach
Milk is rich in nutrition, but if you drink it on an empty stomach, because most of the milk is water, it will dilute the gastric juice and affect its digestion and absorption; in addition, milk is liquid, and the retention time in the gastrointestinal tract is short, so it is difficult to fully absorb the nutrients, so it is best to eat bread, cake dry and other food and milk at the same time.
Tryptophan, a fatiguing substance in milk, has a calming effect on the human body.
If you drink a glass of milk on an empty stomach in the morning, you may feel tired in the morning, which will affect the work and learning effect in the daytime.
Drinking a glass of milk before going to bed can supplement nutrition, promote sleep and ensure full rest, especially for people with neurasthenia and poor sleep.
The harm of drinking milk on an empty stomach in the morning
1. Hindering digestion
As water accounts for a large proportion in milk, drinking more milk on an empty stomach dilutes the gastric juice, which is not conducive to the digestion and absorption of food. In addition, when the stomach is empty, the intestine wriggles quickly, milk passes through the stomach and intestines very quickly, and the retention time is very short. The nutrients are often not absorbed, so they rush into the large intestine and walk through the field. Therefore, drinking milk on an empty stomach is not in line with nutritional health.
2. Gastrointestinal burden
Drinking milk on an empty stomach is not only easy to cause the waste of nutrients, but also may bring great burden to the stomach and human body, thus further affecting human health. Drinking milk on an empty stomach can lead to the rapid elimination of the protein from the stomach, and the wasted precious protein will also be broken down by the human body as heat to be consumed. This process not only can't make the protein play its due role, but also some amino acids are discharged into the large intestine without being absorbed in the small intestine.
And this kind of material will be decomposed into harmful substances, which will increase the burden of human body. Therefore, experts specially remind that before drinking milk, you must eat some staple food, which can avoid the burden on the human body.
3. Produce harmful substances
If you drink milk on an empty stomach, not only will milk be quickly discharged from the stomach, but also high-quality protein will be decomposed by the human body as heat and consumed, which can not fully play the role of protein. Some amino acids are discharged into the large intestine without being absorbed in the small intestine. In the large intestine, these proteins and amino acids are decomposed and become harmful substances, which increases the burden on the human body.
4. Loss of nutrition
Compared with the elderly, the young people now have the habit of drinking milk for breakfast, which was originally a very good eating habit. But if the method of drinking milk is not correct, it will also seriously affect human health, and may also lead to the waste of nutrition. The reason why we can't drink milk on an empty stomach at breakfast is that after a night's sleep and rest, our stomach has been emptied and we are fully prepared to eat and digest food.
Therefore, the gastric emptying is very fast at this time, and milk belongs to the milk food of fluid, which is discharged into the intestine before being fully digested and absorbed in the stomach after drinking, thus causing the loss and waste of nutrients to a great extent.
Ten notes on drinking milk
First: don't drink milk on an empty stomach
Many people drink milk directly on an empty stomach when they wake up in the morning, even if they don't take other food for breakfast. In fact, this is a very wrong way to drink. Because of the waste of taking milk on an empty stomach, the human body is in a hungry state, so the demand for energy is also relatively large. At this time, the milk taken will be directly converted into heat consumption, which leads to a very short time for milk in the stomach and intestines, which will be excreted out of the body quickly through the gut, which is not conducive to nutrition absorption.
Second: it's better to drink milk without sugar
Many people are used to adding a proper amount of sugar when drinking milk. They think it will make the taste more beautiful. Experts tell us that this method is not correct. Especially the boiled milk can not be added with sugar, because the substances and sugars contained in milk will form a substance called fructose lysine in high temperature, which is harmful to human body. In addition, the addition of sugar in this milk also easily leads to the loss of calcium, which is not conducive to the body's calcium supplement. Therefore, the scientific way of drinking milk is better not to add sugar.
Third: don't eat milk raw
How about raw milk? Many people think that raw milk is the most natural and the best for the body. Experts tell us that milk is best not to eat raw, avoid eating some other bacteria and so on.
Fourth: Boil the milk and take it out immediately
When heating milk, stop heating as soon as you see it boiling, otherwise it is easy to reduce nutrients. The color of the milk will turn brown after boiling for a long time, and the flavor will also be reduced, and the vitamin content will also be lost, which is not conducive to our nutritional intake.
Fifth: do not drink milk with tea
Tea is a drink that many Chinese like. Even some people like to take milk and tea together. In fact, this is a very unhealthy way. Experts tell us that milk contains a lot of calcium, and if milk and tea are taken together, some ingredients in tea will affect the absorption of calcium, which is not conducive to health.
Sixth: don't freeze milk
In summer, in order to avoid the deterioration of milk, many people always like to put them into the freezer for preservation. In fact, this method is not good. The separation of fat protein will occur in the milk at the temperature below zero, which will lead to water sample and poor taste of milk. So, if you want to keep milk, you can put it in the fridge to keep it fresh. Don't refrigerate it.
Seventh: drink milk, don't drink food containing tannic acid and oxalic acid
If milk is taken with substances containing large amounts of oxalic acid and tannic acid, it is easy to cause food to agglomerate in the body, so that the body is not easy to digest and absorb. There are many common foods containing this kind of material, such as spinach, lemon, Bayberry and water bamboo, so we should pay attention to distinguish them every day.
Eighth: keep milk away from light
Milk contains a lot of vitamin B, which can easily be broken down and destroyed if it is exposed to sunlight. Therefore, the daily storage of milk must choose opaque bottles, and the location should also choose a cool place.
Ninth: time to drink milk
What should I pay attention to when drinking milk? The time is also very particular. In order to achieve the maximum effect, the best time to drink milk is at night, which is not only conducive to promoting the body to rest, but also more conducive to the absorption of calcium, which has a good effect on preventing bone loss and osteoporosis.
Tenth: you can't use copper ware to cook milk
In many high-end kitchen appliances on the market, copper is still widely used, such as copper milk pot and heating cup. Xiaobian suggests that if the milk is heated, it is better not to use copper ware, because it will damage the vitamins in the milk, and copper will react with the milk chemically to accelerate the loss of nutrients, which is not conducive to the absorption of the body.
