A persimmon tree is far away, and a few fallen persimmons hang on the branches; this scene is no longer the richness of autumn, but the cold wind and frost. Today's " Frost Descent ", the fruit most related to Frost Descent is persimmon; there are many rumors about persimmons, which will break the rumors and restore science. I hope everyone can taste persimmons healthily.

Can't persimmons and milk be eaten together?

This remark still appears to be "persistence" after years of sieving. A typical "food-incompatible remark" is rumored that "eating persimmons and milk together will cause gastric stones and even death." The truth is far from that.

says that both cannot be eaten, mainly because persimmons contain more tannin ( tannin ), and milk is rich in protein . From the perspective of a chemical laboratory, "tannin + protein" will produce precipitates that are insoluble in gastric acid; in addition, tannin entering the stomach will inactive enzymes in the digestive tract, thereby reducing digestive ability and inducing indigestion. The addition of the "consequences" between the two will lead to serious problems such as gastric stones.

The truth: Any laboratory reaction must consider the "dose (dose)". The so-called "persimmon and milk are eaten at the same time and have stones" are not reliable in daily life.

In fact, the amount of persimmons and milk we usually eat will not cause serious stomach problems at all. Suppose you eat ten persimmons and ten kilograms of milk at the same time at a time, and then you may have temporary indigestion problems, but then adjust the meal and wait for a while to restore your health. The body can restore this process by itself, which has nothing to do with serious injuries such as stones and death.

Like milk, yogurt, eggs, goose meat, sweet potatoes and other foods are also rich in protein. The rumor is that "persimmons cannot be eaten together with these foods. As long as they are eaten at the same time, they will lead to vomiting, bloating, diarrhea, and life-threatening." The principles are actually the same. These so-called food restraint theory are just an excessive exaggeration of individual experience and have no connection with scientific principles. They can all be broken here.

Eating persimmons and crabs together will cause poisoning and death?

In addition to "protein restraint", persimmons also have "heavy metal restraint theory". It is rumored online that "eating persimmons with crabs together will lead to poisoning." The vitamin C in persimmons reacts with the "pentavalent arsenic" in crabs, resulting in the reduction of pentavalent arsenic to trivalent arsenic (diar arsenic trioxide), and this thing is the highly toxic arsenic in the TV series.

However, it is worth noting that "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 a theoretical possibility and cannot be achieved in the actual meal situation. The occurrence of the experiment requires the joint support of "dose" and "external conditions". Calculation and analysis are carried out based on 0.5 mg (maximum) of inorganic arsenic content per kilogram of crab. If we want to reduce all arsenic elements into arsenic and lead to poisoning, we theoretically need to "intake more than 100 kilograms" of crabs at one time, and it is just "possible for poisoning reactions." Can this amount be achieved by normal people? So this is exactly "a weird rumor that is illogical and realistic."

Is the so-called "persimmon disease" related to food incompatibility?

In real life, the "persimmon disease" represented by gastric persimmon stone and persimmon stone intestinal obstruction has indeed made everyone "talk about persimmons", and many people closely link persimmon disease with the so-called "persimmon and XX food cannot be eaten together" food inseparable.

It is worth noting that from a principle point of view, gastric persimmon stone is an upper gastrointestinal disease and is a common clinical disease. The main symptoms are abdominal pain of varying degrees. At the same time, there will also be symptoms such as nausea and vomiting, abdominal distension, belching, and . Sometimes even pieces of persimmon are present in the vomit. From a clinical perspective, gastric persimmon stones are divided into acute or chronic. Acute gastric persimmon stones generally appear in about half an hour after eating a lot of persimmons. When the course of the disease is greater than 6 months, it is a chronic problem.

analyzed the real cases in most literature. In fact, most of the patients with gastric persimmon stones suffer from different degrees of stomach diseases. In other words, weakening or disordered stomach function caused by stomach diseases may be an important reason for the formation of persimmon stones. For these people, even if they eat other fruits other than persimmons without reason (hawthorn, black date , etc.), they may experience various stomach discomfort symptoms themselves.

Therefore, although persimmons and high-protein foods such as milk and crabs will have various reactions in principle, based on the mechanism of "polyphenol-protein" interaction, the existing persimmon stone formation mechanism, the characteristics of persimmon stone patients and their clinical treatment methods can be found that the causes of persimmon stones (gastric persimmon stones) are in conflict with the polyphenol -protein restriction theory, so the cause of the disease cannot be judged arbitrarily due to diet. Why do

have multiple "persimmon +" incompatible remarks?

Whenever persimmons are on the market, the ones that are earlier than they are necessarily related to them are all kinds of "food restraint theories". Why is this? First, persimmons have certain "small defects" in themselves. Because of their high tannic acid content, there is capital to be hacked; second, things that are particularly loved will breed hot spots, because people really like to eat persimmons and like their sweetness, so this kind of remark that is closely related to their own health will spread rapidly; third, various factors such as business interests driven by, marketing communication may also lead to the multi-channel dissemination of such remarks.

Remarks about "food restraint", food restraint leads to poisoning and death, etc., are mostly accidental coincidences in nature. They may be simple food poisoning caused by unclean food intake (threat of harmful substances such as bacteria and pesticides), food safety issues, or food allergy manifestations caused by special constitutions, or improper food eating methods (beans are not heated and matured, sprouted potatoes, etc.), or even coincidence (I happened to eat certain types of food before the harm appeared), and I made arbitrarily judge without clarifying the causal relationship. This is a kind of disrespect for science.

In short, the so-called "food restraint theory" requires rational analysis and judgment based on its own situation, and this theory is completely untenable at the scientific level. In the case of good health, as long as everyone does not eat too many persimmons at once, it is OK to eat them with any food.

As the name suggests, persimmon itself is a food that is not easy to digest:

rosy persimmon, but it is actually not easy to digest. It contains a large amount of soluble tannic acid ( tannin ) and pectin, and tannic acid coagulates when it encounters protein. It is precisely because of this characteristic that the entry of a large amount of tannin will interact with the proteins in the stomach under the bearing of gastric acid, which will destroy the "tertiary structure" of protein molecule , forming a high viscosity precipitation, precipitation in the stomach, and bond with the difficult-to-digest plant fibers, affecting the normal work of the stomach.

Eat persimmons safely and healthyly, and control of details is very important:

• persimmons are very astringent, and they should be removed before eating:

The astringent of persimmons comes from the tannins in it. The tannin content in immature persimmons is particularly high, and tannins will stimulate the nerve endings in the oral mucosa and produce an unpleasant taste. To reasonably remove astringent, it is recommended that you store the persimmons and ripe bananas or apples in a tightly tied food bag for a few days. The ethylene released by ripe fruits can ripen unripe persimmons and reduce the astringent taste. In addition, the persimmon skin has a higher tannic acid content, so it is recommended that you "eat persimmons but not skins."

• Persimmons should be limited to: 7

Eat a lot of persimmons, the digestive system is burdened with heavy burden, and it is easy to produce "discomfortable" reactions. Eat moderately and seek benefits and avoid harm. For healthy people, it is recommended to consume more than 2 persimmons per day. It is reasonable to allocate them according to your preferences and physical ability to withstand them. Leave some amount for other fruits. Excessive amount is a burden.

Special populations should strictly control the amount, such as people with weak digestive ability, diabetes patients, and middle-aged and elderly people. In addition, tannin has an effect on the absorption of mineral iron. People with iron deficiency anemia do not recommend eating persimmons for a long time, on the premise of clarifying the cause of their own disease.

• Relatively speaking, it is not recommended to eat on an empty stomach:

In an empty stomach, the stomach is in a highly acidic environment, and tannins are more likely to form lumps when they encounter proteins. Eating persimmons on an empty stomach is higher risk of gastrointestinal discomfort. On the basis of strict control of the amount, eat some vegetables, beans, grains and other foods first, wait for about half an hour before eating persimmons, leaving some buffer for the gastrointestinal tract.

• After eating, rinse your mouth (brush your teeth) to protect your teeth:

The delicious food of persimmons comes from a large amount of sugar. Excessive intake will undoubtedly pose a threat to the teeth. It is recommended to rinse your mouth or brush your teeth after eating persimmons to help you stay away from caries .

"The wall is full of yellow persimmons, and people are competing for the show in autumn." Now is the ripe season for persimmons. The sweet taste of rosy lanterns seems to penetrate the thin layer of skin... The goodness of all things comes from rational treatment, and it should be like this when tasting persimmons. Although food does not exist, the taste still needs to be appropriate and moderate. The way to eat fresh and scientific attitude is intertwined. This is the autumn gift of persimmons.
