There is a persimmon tree in the distance, with several fallen persimmons hanging on the branches; this scene is no longer the abundance of autumn, but the cold wind and frost. Today’s “Shuangjiang”, the fruit most related to the frost is persimmons; there are many rumors about persimmons, break the rumors, restore science, and hope that everyone can enjoy persimmons healthily.
Can persimmon and milk be eaten together?
This remark is still “enduring” after years of sifting, a typical “food refraining speech”, there is a rumor that “eating persimmons and milk together can cause stomach stones and even death “The truth is far from that.
It is said that the two cannot be eaten, mainly because persimmons contain more tannic acid (tannic acid), while milk is rich in protein, and from the perspective of chemical laboratories, “tannic acid” “+ protein” will generate a precipitate that is insoluble in gastric acid; in addition, the entry of tannic acid into the stomach will inactivate the enzymes in the digestive tract, thereby reducing the digestive ability and inducing indigestion. The “consequences” of the two add up, which can lead to serious problems such as stomach stones.
Truth: Any laboratory reaction must take into account the “dose (consumption)”, the so-called “persimmons and milk consumed at the same time for half an hour died, suffered from stones” in Daily life is not reliable at all.
Actually, the amount of persimmons and milk we normally eat is not at all likely to cause serious stomach problems. Suppose you eat ten persimmons and ten catties of milk at the same time, and then you may experience some indigestion problems temporarily, but after adjusting your meal, you can restore your health after a while. Other serious injuries are not associated.
Like milk, yogurt, eggs, goose, sweet potatoes and other foods are also rich in protein. It is rumored that “persimmons and these foods cannot be eaten together, as long as they are eaten at the same time, it will cause vomiting, abdominal distension, Diarrhea, life-threatening” principles are actually the same. These so-called food-related theories are just exaggerated exaggerations of individual experience and have no connection with scientific principles.
Eating persimmon and crab together will cause poisoning and death?
In addition to the “protein suppression”, persimmons also have “heavy metal suppression theory”. According to the Internet, “eating persimmons and crabs together will lead to poisoning”, the vitamin C in persimmons and the “five” in crabs Arsenic “will react, causing pentavalent arsenic to be reduced to trivalent arsenic (arsenic trioxide), which is the highly toxic arsenic in the TV series.
However, it is worth noting that the “reduction of Vc with pentavalent arsenic to trivalent arsenic” can only be done in the laboratory, and the experimental conditions are particularly harsh, this is only theoretical It is possible that it is impossible to achieve in the real meal situation. The occurrence of the experiment requires the joint support of “dose” and “external conditions”. The calculation and analysis are carried out according to the inorganic arsenic content of 0.5 mg (maximum) per kilogram of crabs. In order to reduce all the arsenic elements into arsenic and cause poisoning, theoretically It requires us to “one-time” intake of “more than 100 kilograms” of crabs, and only “possible poisoning reactions”. Can a normal person achieve this amount? So this is exactly “weird rumors that do not conform to logic and reality”.
Is the so-called “persimmon disease” related to food restraint?
In real life, the “persimmon disease” represented by persimmon stone in the stomach and intestinal obstruction caused by persimmon stone really makes everyone “talk about the discoloration of persimmon”, and many people associate persimmon disease with the so-called “persimmon disease”. “Persimmons and XX foods cannot be eaten together” are closely related to the food sympathy theory.
It is worth noting that, in principle, gastric persimmon stone is a disease of the upper gastrointestinal tract, which is a common clinical disease. The main symptoms are abdominal pain of varying degrees, as well as nausea and vomiting. , abdominal distension, belching and other symptoms, and sometimes even broken persimmon in the vomit. From a clinical point of view, gastric persimmon stone is divided into acute or chronic. Acute gastric persimmon stone usually occurs about half an hour after eating a lot of persimmons, and it is a chronic problem when the disease duration is longer than 6 months.
According to the analysis of real cases in most of the literature, most of the people suffering from gastric persimmon stone suffer from different degrees of gastric disease. That is to say, the weakened or disordered gastric function caused by gastric diseases may be an important reason for the formation of persimmon stones. For these people, even if they eat other fruits (hawthorn, black dates, etc.) other than persimmons unreasonably, they may experience various symptoms of stomach discomfort.
Therefore, although persimmons and milk, crabs and other high-protein foods will have various reactions in principle, according to the mechanism of “polyphenol-protein” interaction, the existing persimmon mechanism of stone formationA comprehensive analysis of the characteristics of patients with persimmon stones and their clinical treatment methods shows that the causes of persimmon stones (gastric persimmon stones) have great contradictions and conflicts with the theory of polyphenol-protein restriction. reason.
Why are there multiple “persimmon+” remarks on each other?
Every time a persimmon goes on sale, it must be a variety of “food-related theories” that precede it. Why? First, the persimmon itself has certain “small defects”, because of its high tannic acid content, it has the capital to be hacked; second, the favorite things will breed hot spots, because everyone really likes eating persimmons, and they like it. Sweet, so such remarks that are closely related to one’s own health will spread rapidly; thirdly, various factors such as business interests and marketing communication may also lead to the multi-channel dissemination of such remarks.
The remarks about “food is incompatible with each other”, and food inhibits each other leading to poisoning and death, are mostly accidental coincidences in nature, which may be due to unclean ingestion of food (bacteria, pesticides and other harmful substances) Threats), simple food poisoning caused by food safety problems, or food allergies caused by special constitutions, or improper food eating methods (unheated beans, eating sprouted potatoes, etc.), or even possible It is a coincidence (just eat certain kinds of food before the hazard appears), and making judgments without knowing the cause and effect relationship is a kind of disrespect for science.
In short, the so-called “food rationing theory” needs to make rational judgments according to its own situation, and this theory is completely untenable at the scientific level. In the case of good health, as long as you don’t eat too many persimmons at one time, you can eat them with any kind of food.
As the name suggests, persimmons are inherently difficult to digest:
A rosy persimmon is actually not easy to digest. It contains a lot of soluble tannin (tannin) and pectin, and tannin will solidify when it encounters protein. It is because of the existence of this characteristic that the entry of a large amount of tannic acid will interact with the protein in the stomach under the load of gastric acid, which will destroy the “tertiary structure” of the protein molecule, form a high-viscosity precipitate, and precipitate in the stomach. It binds together with indigestible plant fibers and affects the normal work of the stomach.
Eating persimmons safely and healthily, it is crucial to control the details:
Persimmons are very astringent, so remove the astringency before eating:
The astringency of persimmons comes from the tannins in them, which are especially high in immature persimmons, and tannins can stimulate nerve endings in the oral mucosa, resulting in an unpleasant taste. To remove astringency reasonably, it is recommended that you store persimmons and ripe bananas or apples in a fastened food bag for a few days. The ethylene released by ripe fruits can ripen the unripe persimmons and reduce the astringency. In addition, the tannic acid content in persimmon skin is higher, it is recommended that everyone “eat persimmon without skin”.
Limited persimmons:
Eat a lot of persimmons, the burden on the digestive system is heavy, and it is easy to produce “uncomfortable” reactions. Eat in moderation, seek benefits and avoid harm. For healthy people, it is not recommended to consume more than 2 persimmons per day, and allocate them reasonably according to their own preferences and physical tolerance, and leave some amount for other fruits. Excessive consumption is a burden.
Special populations should strictly control the amount, such as people with weak digestion, diabetics, and middle-aged and elderly people. In addition, tannic acid has an impact on the absorption of mineral iron. People with iron deficiency anemia are not recommended to eat a lot of persimmons for a long time under the premise of knowing the cause of their disease.
In contrast, it is not recommended to eat on an empty stomach:
In the fasting state, the stomach is in a highly acidic environment, and tannins are more likely to form hard lumps when encountering proteins. Eating persimmons on an empty stomach is more likely to cause gastrointestinal discomfort. On the basis of strict control of the amount, first eat vegetables, beans, grains and other foods, and wait for about half an hour before eating persimmons to leave some buffer for the stomach.
Rinse (brushing) after eating to protect your teeth:
The deliciousness of persimmons comes from the large amount of sugar in them. Excessive intake will undoubtedly pose a threat to the teeth. After eating persimmons, it is recommended to rinse your mouth or brush your teeth to help you stay away from tooth decay.
“The walls are full of yellow persimmons, and people are competing for the autumn harvest.” Now is the ripening season for persimmons. The ruddy little lanterns seem to penetrate the thin layer of sweetness. The skin… The good of all things comes from rational treatment, especially persimmons. Although food does not exist, the taste still needs to be in moderation and moderation. Fresh eating methods and scientific attitudes are intertwined. This is the autumn gift that belongs to persimmons.
