Introduction
Under normal circumstances, apple cider vinegar cannot prevent colds. When consuming apple cider vinegar, it is important to maintain moderation, as its high acidity may irritate the gastrointestinal mucosa and cause discomfort such as stomach pain and acid reflux if consumed in excessive amounts. Individuals with excessive stomach acid or gastric ulcers should consume it with caution. It is recommended to dilute apple cider vinegar before drinking to reduce irritation to the gastrointestinal tract.
Generally speaking, apple cider vinegar cannot prevent colds. The detailed explanation is as follows:
Colds are primarily caused by viral infections, such as rhinoviruses and coronaviruses. These viruses enter the body through the respiratory tract and cause symptoms like nasal congestion, runny nose, and coughing. Preventing colds requires scientifically proven methods such as boosting immunity, practicing personal protection, and avoiding contact with pathogens. Apple cider vinegar is a beverage made from fermented apples. Although it contains some organic acids and vitamins, these components do not have the ability to kill cold viruses or prevent viral infections. Currently, no authoritative scientific research has confirmed that apple cider vinegar is effective in preventing colds.
When consuming apple cider vinegar, moderation is important, as its high acidity may irritate the gastrointestinal mucosa when consumed in excess, potentially causing discomfort such as stomach pain and acid reflux. Individuals with excessive stomach acid or gastric ulcers should be especially cautious. It is recommended to dilute it before consumption to reduce gastrointestinal irritation. When purchasing, choose products from reputable manufacturers to ensure quality and safety, and avoid consuming unregulated or substandard products that may harm your health.
