Apple Cider Vinegar Risks: Who Should Avoid It Completely
Apple cider vinegar is made by fermenting apples and is often used for weight loss.
It is acidic, so drinking it can hurt teeth, the throat, and the stomach.
Some people may feel nauseated, bloated, or overly full after taking it.
Large or long-term amounts may lower potassium levels.
People with reflux, ulcers, kidney disease, or damaged tooth enamel may be especially vulnerable.
