Kiwi is a laxative but "heartburn". Kiwi can relieve constipation and is rich in vitamin C, so it is called "the king of fruits". Kiwifruit is cold, and overeating damages the spleen and stomach yang, resulting in abdominal pain, diarrhea and other symptoms. In addition, a large amount of vitamin C and pectin contained in kiwifruit will increase gastric acid, increase the burden on the stomach, and produce symptoms such as abdominal pain, pantothenic acid and heartburn, which will be aggravated when the weather is cold. In such a cold season, patients with stomach diseases (spleen and stomach yang deficiency) should eat less or even not eat kiwifruit. Fresh dates are delicious, but dates are Pi Zha's stomach. Winter jujube is known as a natural "vitamin pill". Wang Xingguo, director of the Nutrition Department of Dalian Central Hospital, warned that fresh dates should not be eaten too much, otherwise it would hurt the stomach. This is because the dietary fiber content of jujube is very high, and a large amount of intake will stimulate the stomach and cause gastrointestinal discomfort. Dietary fiber mostly exists in jujube skin, which is thin and hard with sharp edges. If the gastric mucosa just has inflammation or ulcer, it will aggravate the pain and discomfort. Hawthorn appetizing is easy to cause stones. Many people think hawthorn is appetizing, sweet and sour, and they will eat a lot if they are not careful. People with poor spleen and stomach eat less hawthorn, and eating too much hawthorn may lead to stomach stones. Because of the high content of pectin and tannic acid in hawthorn, it is easy to condense into water-insoluble sediment after contact with gastric acid, which will bond with food residues to form gastrolith, which can cause gastric ulcer, gastric bleeding and even gastric wall necrosis and perforation. But boiling hawthorn will reduce the effect of tannic acid.
