Vinegar has a good health-preserving effect, which can help lower blood lipid and blood pressure. Jiaozi dipped in vinegar can also play the role of seasoning to relieve boredom, but people with gastric ulcer or hyperacidity are not suitable for jealousy, so as not to increase gastric acid, stimulate gastrointestinal mucosa and aggravate ulcers. In addition, some friends are used to dipping in soy sauce or Chili oil when eating jiaozi, which is unhealthy. Adding soy sauce will make people consume extra salt, which is not conducive to cardiovascular and cerebrovascular health; Although pepper can stimulate fever, it is spicy and irritating, which is not suitable for cold and dry winter, nor for people with yin deficiency. Similarly, eating jiaozi with raw garlic cloves is enjoyable, but it is also a spicy product. For friends with stomach problems, it is better to eat less.
