Taboos of jealousy

1. Patients with gastric ulcer and hyperacidity should not consume vinegar. Because vinegar will not only corrode the gastrointestinal mucosa and aggravate the development of ulcers, but also vinegar itself is rich in organic acids, which can cause the digestive organs to secrete a large amount of digestive juice, thus increasing the digestive function of gastric acid to prevent increased gastric acid and aggravation of ulcers.

2. People who are allergic to vinegar and those with low blood pressure should avoid using it. Vinegar can cause allergies in the body, leading to symptoms such as rash, itching, edema, and asthma. Some people who are not used to vinegar should consume it with caution. Patients with hypotension who consume vinegar will lower their blood pressure, causing headaches, dizziness, general weakness and other adverse reactions.

3. The elderly should avoid being jealous during fracture treatment and recovery. Because vinegar can soften bones and decalcify, destroying the dynamic balance of calcium in the human body, it can promote and aggravate osteoporosis. The injured limb becomes sore, the pain worsens, and the fracture is delayed in healing.

4. No matter how strong your gastrointestinal system is, it is not suitable to drink vinegar on an empty stomach to avoid stimulating the secretion of excessive gastric acid and damaging the stomach wall. Drinking vinegar between meals or one hour after meals is less irritating to the gastrointestinal tract and helps digestion.
