1, the harm of drinking milk on an empty stomach
1, which hinders digestion
Because water accounts for a large proportion in milk, drinking more milk on an empty stomach dilutes gastric juice, which is not conducive to the digestion and absorption of food. In addition, on an empty stomach, the intestinal peristalsis is very fast, the speed of milk passing through the gastrointestinal tract is very fast, and the retention time is also very short. Its nutrition is often too late to be absorbed, so it rushes into the large intestine and goes through the motions. Therefore, drinking milk on an empty stomach is not in line with nutrition and hygiene.
2, produce harmful substances
If you drink milk on an empty stomach, not only will the milk be discharged from your stomach quickly, but also the high-quality protein will be decomposed by your body and consumed as heat, which will not give full play to the due role of protein. Some amino acids are excreted into the large intestine before being absorbed by the small intestine. In the large intestine, these protein and amino acids are decomposed into substances harmful to human body, which increases the burden on human body.
3. Gastrointestinal burden
Drinking milk on an empty stomach is not only easy to waste nutrition, but also may bring great burden to the stomach and human body, thus further affecting human health. Drinking milk on an empty stomach will cause protein to be quickly excreted from the stomach, and these wasted precious protein will be decomposed by the human body and consumed as calories. This process not only failed to make protein play its due role, but even some amino acids were discharged into the large intestine before being absorbed by the small intestine. Moreover, this substance will be decomposed into substances harmful to human body, thus seriously increasing the burden on human body. Therefore, experts especially remind that you must eat some staple foods before drinking milk, so as not to burden the human body.
4. Nutrition loss
Compared with the elderly, young people now have the habit of drinking milk for breakfast, which was originally a very good eating habit. However, 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 stomachs have already been emptied and we are fully prepared to eat and digest food.
2. The health care function of milk
1. Potassium in milk can keep arterial blood vessels stable under high pressure and reduce the risk of stroke.
2. Milk helps to prevent the human body from absorbing the toxic metals lead and cadmium in food.
3. Tyrosine in milk can promote the increase of serotonin.
4. Iron, copper and lecithin in milk can greatly improve the working efficiency of the brain.
5. Calcium in milk can strengthen bones and teeth and reduce the occurrence of skeletal atrophy.
6. Magnesium in milk can make the heart anti-fatigue.
7. Zinc in milk can make the wound heal faster.
8. Vitamin B in milk can improve eyesight.
9. Drinking milk regularly can prevent arteriosclerosis.
10, milk has high calcium content and good absorption.
3. Precautions for drinking milk
1, boiled milk without sugar.
Many people have the habit of adding sugar when boiling milk, but this practice is not conducive to the health of the Eucharist, because milk contains lysine, and fructose contained in white sugar will produce fructosyl lysine when drunk at high temperature, which can not only be absorbed by the human body, but also destroy the nutritional value of milk; More importantly, it will do some harm to the body.
2, drinking milk is not suitable for drinking.
Some people are used to drinking milk at the dinner table, which is actually a bad practice, because milk tastes sweet and slightly cold, while liquor tastes sweet and slightly spicy, so these two foods with opposite properties and functions should not be eaten together. Moreover, ethanol can inhibit the oxidative decomposition of fat and promote the synthesis of fat, and most of milk contains fat. If you drink with ethanol, heavier fat will gather in the liver, thus inducing the formation of fatty liver. In addition, alcohol is protein denaturation in milk, which greatly reduces the nutritional value of milk.
Milk should not be eaten with vinegar.
Some people think that adding vinegar to milk can reduce weight, but this view is not conducive to health. Because vinegar contains organic acids such as acetic acid, if it is eaten with milk, it will easily lead to agglutination and precipitation of milk, which is not easy to be digested and absorbed. For people with insufficient stomach, it is more likely to cause indigestion and even diarrhea symptoms.
Milk should not be eaten with chocolate.
Liquid milk and chocolate can make calcium in milk react with oxalic acid in chocolate to produce "calcium oxalate", which will turn calcium beneficial to human body into harmful substances, thus leading to symptoms such as diarrhea. If children eat it for a long time, they may also have symptoms such as stunting, dry hair, easy fracture and urinary calculi.
5. Milk should not be drunk with juice.
If excessive juice is added to milk, casein in milk will react with juice, resulting in agglutination and precipitation, which makes it difficult for human body to digest and absorb. More serious will cause indigestion and diarrhea.
6, milk should not be eaten with drugs.
Some people like to take medicine with milk instead of boiling water. In fact, milk will obviously affect the human body's absorption of drugs. Because milk is easy to form a covering film on the surface of drugs, minerals such as calcium and magnesium in milk react with drugs to produce water-insoluble substances, thus affecting the release and absorption of drug effects. So don't drink milk before and after taking the medicine 1 hour.
