If you eat the sour and sweet Bingtanghulu and the delicious Roasted chestnuts in sugar-coated heated sand together, you may get stomach stones? Not long ago, a news that "doctors remind hawthorn and chestnuts not to eat together" became a hot Internet search, and Bingtanghulu and Roasted chestnuts in sugar-coated heated sand were also "lying on the gun". So, can't these two seasonal "craving tools" really "meet" in the same stomach at the same time? Ruan Guangfeng, Deputy Director and Associate Research Librarian of Kexin Food and Health Information Exchange Center, stated in an interview with China Consumer News that currently, there is no sufficient evidence to suggest that mixing hawthorn and chestnuts can directly cause stomach stones in healthy individuals. As long as the consumption is controlled and not consumed in large quantities at once, it is sufficient. If it is Bingtanghulu and Roasted chestnuts in sugar-coated heated sand, it is not suitable to eat too much because there is more sugar. Ruan Guangfeng explained that stomach stones are lumpy substances formed by the retention of things that cannot or are difficult to digest in the stomach. These substances can neither be digested nor pass through the pylorus smoothly, so they stay in the stomach for a long time and gradually form stones under the action of stomach acid. From the current epidemiological survey and analysis of patients with stomach stones, it is easy to occur in the elderly, diabetes patients, and people who have previously had peptic ulcer and other stomach diseases. According to the composition of gastric stones, they can be roughly divided into plant stones, hair stones, drug stones, and mixed stones. Among them, plant-based gastric stones are the most common, mainly composed of various undigested plant components, including tannic acid, cellulose, pectin, gum, etc. Persimmon stone and hawthorn stone are the most common plant-based stones. The saying "hawthorn and chestnut cannot be eaten together" is because hawthorn contains tannic acid, and chestnuts contain dietary fiber and starch, which can lead to stomach stones. In fact, this situation is more likely to occur in people with poor gastric function, such as those with digestive diseases such as gastric ulcers and gastritis, who are prone to stomach acid reflux. If they happen to eat too much of these foods, a large amount of tannic acid, gum, dietary fiber and other substances will react with stomach acid chemically, producing insoluble precipitates that slowly form clumps and become stomach stones. There is no problem for normal people to eat this way, and not all hawthorn contains a lot of tannic acid, because if the tannic acid content is high, the taste will be particularly astringent. Regular hawthorn sold has undergone de astringency treatment, and the tannic acid content is very low. Of course, consuming any delicious food should be done in moderation. If healthy individuals consume too much of a certain food in a short period of time, it can also increase the digestive burden on the gastrointestinal tract. Over time, this can lead to impaired gastrointestinal function and increase the risk of developing gastrointestinal diseases. (Lixin News Agency) (Reporter Li Jian)
