Is apple cider vinegar safe to drink if lemon juice is?

While lemon juice is generally considered safe to drink, the same cannot be said about apple cider vinegar. Apple cider vinegar is highly acidic and can cause damage to the teeth, esophagus, and stomach if consumed undiluted. It is recommended to dilute apple cider vinegar with water before consuming it. Additionally, individuals with certain medical conditions, such as gastroesophageal reflux disease (GERD), should consult with a doctor before consuming apple cider vinegar.
