Apple cider vinegar (ACV) has been labeled as a natural remedy and is even touted as a “miracle” to reduce blood pressure, ward off cancer, induce weight loss, and more. However, not all of its supposed benefits have been proven or completely supported by science.
While there is no harm in consuming small amounts of it, too much ACV in your diet can, unfortunately, lead to adverse health effects. Here are five of them you should know about.
1. Stomach problems
ACV can be aggravating for some individuals who may already suffer from ulcers, inflammation, or simply have a sensitive stomach. While possible complications usually include stomach cramping and diarrhea, drinking too much ACV may potentially cause erosion of stomach lining.
2. Dental decay
In a 2014 study, researchers immersed samples of human enamel in vinegar of varying pH levels and found a small risk of erosion, limited due to the laboratory setting. But experts believe tooth decay is a possibility when consumption is in excess.
“Large amounts of apple cider vinegar may cause dental erosion,” said clinical cardiologist Dr. Luiza Petre. “The acetic acid in vinegar may weaken dental enamel and lead to loss of minerals and tooth decay.”
3. Temporary weight loss
While many celebrities have claimed that drinking ACV helped them lose weight, it should not be perceived as a magic weight-loss bullet, said NYC-based dietitian Jaclyn London.
Depending on ACV alone could only reduce water weight, leading to a temporary weight loss like the one you may experience from a crash diet. However, if using it as dressing that motivates you to eat salads, it can definitely be a healthful part of your efforts to maintain a healthy weight.
4. Lower potassium
Drinking ACV could cause potassium levels in the blood to fall to insufficient levels, a condition known as hypokalemia. Caution is specifically advised for people who take certain medications that interfere with potassium levels in their body, the most common one being diuretics — used to treat high blood pressure.
5. Appetite issues
As per anecdotal evidence, some people try to use ACV as an appetite suppressant, usually by drinking it in a very diluted form. But registered dietitian Leslie Bonci notes how this could end up backfiring and cause excessive hunger due to the very low-calorie content.
“You feel full for the moment that you’re having it because you’ve just consumed a gallon of water, but when you pee that out, you’re going to be hungrier, sooner,” she explained.
Let it also be said that it is never a good idea to starve yourself. Make sure your daily calorie intake is adequate and try to include more fruits, vegetables, protein sources, and carbohydrates in your diet.
