A person can get tooth decay if they consume too many acidic foods. Like all vinegars, apple cider vinegar is acidic. Consuming too many acidic foods and beverages can weaken tooth enamel over time, potentially leading to tooth decay.
According to Dr. Robert H. Shmerling, an associate professor of medicine at Harvard Medicine School in Boston, MA, there have been reports of apple cider vinegar causing or worsening low potassium levels.
Some research suggests that consuming vinegar can affect how the body regulates blood sugar levels. However, scientists do not fully understand this effect and more research is needed.
Many people recommend vinegar as a natural weight loss aid. Research suggests that it helps slows the rate at which food leaves the stomach, which can suppress the appetite by making a person feel fuller for longer.
The acidity of vinegar means that applying it directly to the skin can cause burns and irritation, especially if the vinegar is undiluted.
Regularly consuming large quantities of undiluted vinegar can lead to side effects.
A 2016 review found that people may be able to achieve many of the potential health benefits by drinking around 15 milliliters of vinegar a day or any quantity that contains around 750 milligrams of acetic acid.
Consuming apple cider vinegar has become a popular health trend.
