Can apple cider vinegar regulate the body's acid-base balance?

Generally speaking, apple cider vinegar cannot regulate the body's acid-base balance. The detailed explanation is as follows:

The human body possesses a sophisticated acid-base regulatory system, including buffer substances in the blood, and the regulatory functions of the lungs and kidneys, which maintain the acid-base balance of body fluids within a stable range. External intake of food rarely affects this balance. Although apple cider vinegar tastes acidic, after entering the body, it undergoes digestion and metabolism, and its metabolic byproducts have a negligible effect on the overall acid-base environment within the body. Regardless of whether acidic or alkaline foods are consumed, the body will counteract their effects through its own regulatory mechanisms, maintaining a stable acid-base balance. Therefore, apple cider vinegar cannot effectively regulate the body's acid-base balance.

When drinking apple cider vinegar, it is important to consume it in moderation and avoid taking it on an empty stomach to prevent irritation of the gastric mucosa. It is best to dilute it before consumption to reduce its corrosive effects on teeth. Patients with excessive stomach acid or peptic ulcers should avoid drinking it to prevent worsening of symptoms. When purchasing apple cider vinegar, choose products from reputable brands and avoid varieties with excessive added sugar. If gastrointestinal or oral discomfort occurs after consumption, discontinue use immediately.
