White vinegar and salt are common foods that do not produce special chemical reactions that produce potent medicinal ingredients, so they do not have a role in treating or preventing disease. Ordinary white vinegar is generally an acetic acid-based condiment produced by fermentation of glutinous rice and other raw materials. The main component of salt is sodium chloride, and some salt contains iodine. Acetic acid and salt, will not have a magical chemical reaction that produces any substances for treating and preventing diseases. So acetic acid and salt have no special effects. Acetic acid is mildly acidic and has an aromatic flavor, which helps increase appetite and gives dishes a multilayered taste. However, those who suffer from gastroesophageal reflux, gastric ulcer and chronic gastritis diseases need to limit the consumption of white vinegar appropriately, and the symptoms are easily aggravated by consuming too much. Dietary guidelines for Chinese residents recommend that the daily intake of salt should not exceed 5 grams, otherwise it is easy to increase the risk of high blood pressure and cardiovascular and cerebrovascular diseases. The diet should be light, with less salt and oil, and acetic acid with salt has no special effect. If there is physical discomfort, please consult a doctor as soon as possible, complete the examination and cooperate with the doctor’s treatment.
