Why do you get stone disease when you drink milk and cola at the same time?

The crystals of calcium carbonate are very small, and after reaching the stomach, they will not form large stones, but will enter the intestines under the peristalsis of the stomach, and then enter the absorption. If it cannot be absorbed, it will be excreted through the stool, and there will be no risk of stones. Some medicines themselves are calcium carbonate, such as calcium supplements, the ingredient is calcium carbonate, which not only will not form stones after eating, but can also achieve the effect of calcium supplementation.

Experiments showed that no calcium carbonate was found in the precipitate. So is it possible to prove that milk and cola are mixed together to produce calcium carbonate at all? Zheng Yanying said that it was not possible to draw conclusions about this, and in order to make the experiment more rigorous, she replaced ordinary milk with high-calcium milk and conducted another experiment to observe whether calcium carbonate was present in the sediment.

After the experiment, a small amount of white material appeared at the bottom of the centrifuge tube, and then hydrochloric acid was added to the white precipitate for verification. The white precipitate dissolves quickly when it encounters hydrochloric acid, and at the same time gas is released. This proves that mixing high-calcium milk and cola together does produce a small amount of calcium carbonate in addition to casein precipitation.

Zheng Yanying told reporters that a small amount of calcium carbonate can be decomposed by hydrochloric acid in gastric juice.

Zheng Yanying, an associate professor in the Department of Chemistry at the School of Biology of Beijing University of Agriculture, conducted an experiment by first taking 40 ml of cola and pouring it into a beaker, and then taking 4 ml of ordinary fresh milk. The two are then gradually mixed. When cola and milk are mixed, a large amount of sediment is produced.

Subsequently, the precipitate from the beaker was poured into two centrifuge tubes for centrifugation test, and hydrochloric acid and sodium hydroxide were added to the separated precipitate. The results showed that the precipitate did not react with hydrochloric acid in any way, but reacted with sodium hydroxide and the precipitate disappeared. This proves that the precipitate is not calcium carbonate.

Zheng Yanying told reporters, "milk contains a lot of casein, the pH value of cola is about the same, when milk is added to cola, this flocculation phenomenon is likely to be formed by casein reaching the isoelectric point precipitation, casein also has a property of alkali dissolution, so sodium hydroxide is added to the precipitate, and the precipitate is found to disappear completely, so it proves that the mixed sediment of cola and milk is casein." ”<

Jia Kai, deputy chief physician of the Department of Nutrition of Beijing Chaoyang Hospital affiliated to Capital Medical University, said that the flocculent formed after the mixing of cola and milk is mainly precipitated after the denaturation of casein, and the casein itself after denaturation is relatively loose, and will naturally enter a process of digestion and absorption of the human body.

Speaking of drinks, I believe most people will think of cola for the first time, after all, it is still very popular in our country, especially in the hot summer, it can be said that it is a very happy thing to drink a cool coke. But we hear it all the time.

Mixing milk and cola can cause stomach stones, which is unscientific. Although mixing the two can cause a chemical reaction that produces precipitation, it does not necessarily cause stomach stones. Doctors suggest that mixing the two together is not encouraged to be mixed because the sediment produced by mixing the two can affect digestion to some extent, although it is not a big deal.

What happens when you mix Coke with milk.

A transparent zone will gradually form in the bottle, and the color of the cola will become lighter and lighter, and it will be precipitated to the bottom of the bottle, and the sediment will become more and more, and the visual effect is very, shocking and full of magic.

A sip of Coke and a sip of milk is not a big deal for the body. Experts say that milk is a variety of substances that are relatively rich, and adding salt and vinegar will cause protein precipitation. The flocculent sediment produced by the mixture of milk and cola can be absorbed or excreted by the human body in time after the digestion and excretion process of the stomach and intestines, and will not cause gastric stones.

Can you drink cola and milk at the same time.

Experts say that cola is a carbonated beverage that reacts with the proteins in milk to produce a chemical reaction, and the proteins are denatured to form phosphorus blocks. In general, protein denaturation does not affect its safety and nutritional value, only its absorption, but it is recommended that milk and cola not be put together.

No. Zheng Yanying, associate professor of the Department of Chemistry at the School of Biology of Beijing Agricultural University, conducted the experiment. Pour 40 ml of cola into a beaker, then take 4 ml of plain fresh milk and gradually mix the two.

When coke and milk are mixed, a large amount of sediment is produced. Then, the precipitate inside the beaker was poured into two centrifuge tubes for centrifugation test, and hydrochloric acid and sodium hydroxide were added to the separated sediment, respectively. The results showed that the precipitate did not react with hydrochloric acid, but with sodium hydroxide, and the precipitate disappeared.

Therefore, the precipitate is not calcium carbonate.

Zheng Yanying told reporters, "Milk contains a lot of casein, and the pH value of cola is about. When milk is added to cola, coagulation may be caused by the precipitation of casein at the isoelectric point, another property of casein is that it is soluble in alkalis. Therefore, sodium hydroxide is added during the precipitation process and the precipitation disappears completely.

Thus, it turns out that the precipitate precipitated by the mixture of cola and milk is casein. ”

Jia Kai, deputy chief physician of the nutrition department of Beijing Chaoyang Hospital affiliated to Capital Medical University, said that the flocculent formed after mixing cola and milk is mainly precipitated after casein denaturation. Denatured casein itself is relatively loose and naturally enters the body's digestion and absorption process. Under the action of various proteases and trypsin, the nutrients that can be absorbed are absorbed, and stones will not form when they enter the body.

No calcium carbonate was found in the precipitate. So, can it be proven that milk and cola don't produce calcium carbonate at all? Ms. Cheng said she couldn't jump to conclusions.

To make the experiment more rigorous, she replaced regular milk with high-calcium milk and conducted the experiment again to see if the sediment contained calcium carbonate.

After the experiment, a small amount of white material was found at the bottom of the centrifuge tube, and hydrochloric acid was added to the white precipitate for verification. The white precipitate dissolves rapidly in hydrochloric acid and at the same time releases gases. It can be shown that when high-calcium milk and coke are mixed together, a small amount of calcium carbonate is indeed produced in addition to casein precipitation.

Zheng Yanying told reporters that hydrochloric acid in gastric juice can decompose a small amount of calcium carbonate.

The crystals of calcium carbonate are small, Jakai said. When it reaches the stomach, it does not form large stones, but enters the intestines under the peristalsis of the stomach and then into absorption. If it cannot be absorbed, it will also be excreted through the stool, and there is no risk of stones.

There are also some drugs that are calcium carbonate themselves, such as calcium supplementation, which is made up of calcium carbonate. When consumed, they do not form stones and also replenish calcium.

This is true, because there are experimenters who have made such proofs.

I think it's just a rumor, not a real acquaintance.

I don't think it will necessarily be a stone, but it will probably have a big impact.

It seems that many people say this, but whether it is true remains to be examined.

Cola milk is two different flavors of the drink, although cola is a non-nutritious drink, but because of the function of cooling off, it is loved by people from all walks of life.

You may have heard the saying that Coke and milk can't be drunk at the same time, so why can't you drink them at the same time?

Cola is a carbonated drink, and milk is rich in a lot of protein, if the two meet, it will become a chemical reaction, protein will be under the influence of calcium carbonate, form some flocculent precipitate, into the body will affect the absorption of the stomach and intestines, bad stomach friends will vomit and other phenomena. Of course, don't worry, if you accidentally drink it by mistake, it's okay, the intestines and digestive system will excrete them from the body, if you still don't feel well, you need to go to the hospital for treatment in time.

Cola is a carbonated drink, its main components are carbonic acid, sugar, water and coloring, while milk is a high-calcium, high-protein food, containing protein, calcium, vitamins, fat and other minerals, if these two food ingredients are mixed together, it will undergo a chemical reaction, reduce each other's nutritional value and taste, and seriously endanger human health.

Cola contains a large amount of carbonic acid, while milk contains a large amount of mineral calcium, and when these two ingredients are mixed together, a neutralization reaction occurs to produce calcium carbonate that is difficult to dissolve in gastric acid, inhibiting the absorption of calcium in milk and reducing its calcium-supplementing effect. If consumed in this way, urinary tract stones may even occur.

The human body digests and absorbs liquid food relatively quickly, and milk and cola are liquid foods, especially cola, which contains sugar and carbonic acid, and is absorbed very quickly, so if you drink cola first, you can drink milk every ten minutes, and if you drink milk first, you have to drink cola about an hour apart, which can avoid mixing the two in the stomach and intestines.

Because the protein in milk reacts with the substances in the cola, causing stones.

This is a chemical reaction, calcium ions are easy to form stones, so you should pay more attention to it.

Because milk and cola react together, they become solid and adhere to the kidneys.

Because milk and cola can react, the protein in milk will precipitate when it encounters the carbonic acid of cola.

Milk and cola together can cause some undesirable chemical reactions, which have a great impact on the human kidneys, and cannot be effectively discharged, resulting in kidney stones.

In fact, this statement is a bit biased, and it will be a little uncomfortable to drink milk and cola together.

Milk has calcium in it, and cola has carbonic acid in it, and they turn into chemicals. Prone to stones.

Because the cola is mixed with milk, there is a chemical reaction that produces some solids that adhere to the kidneys.

It may be that the milk will neutralize with the cola, and a precipitate is a kind of stone.

What happens when you pour milk into Coke? It is said that drinking this way is easy to get stones.

Cola contains high amounts of phosphates, which can lead to kidney disease; Coke also contains sugar, which can cause people to gain weight and cause diabetes. If everyone drinks more than two glasses of cola a day, the chance of causing chronic kidney disease will increase, cola can reduce the calcium in the bones, which will also increase the chance of kidney stones, kidney failure and other kidney diseases, so cola can cause kidney stones. Generally, drinking too much cola will not cause kidney stones.

Kidney stones are formed due to the crystallization of calcium oxalate in the kidneys, and the formation of stones is related to one's own constitution and poor lifestyle habits. Patients are advised to use medications to drain stones**. At the same time, be sure to do more jumping exercises.

Long-term drinking of a large amount of cola may lead to the appearance of stones, for patients with stones is generally because of long-term sedentary, do not carry out proper exercise, love to eat high-fat, high-sugar foods and snacks, liver cirrhosis and other factors, for gallstone patients need to take surgery to remove the gallbladder, take stones or drugs ** Drinking cola will not cause the formation of stones. The formation of gallstones is associated with frequent skipping of breakfast, as well as frequent consumption of high amounts of fatty and cholesterol-rich foods. Cola is a carbonated drink, which affects calcium absorption and destroys bone density.

It is recommended that you drink as little carbonated drinks as possible, and at the same time pay attention to calcium supplementation to prevent calcium deficiency and osteoporosis.

There will be this situation, try to drink as little as possible, especially if the uric acid is high, you must not drink.
