To make vinegar, apples are combined with yeast so that the apple sugar turns into alcohol. Bacteria are then added so that the alcohol ferments into acetic acid. Acetic acid is the main active component of apple cider vinegar.
Several studies have suggested that acetic acid may help reduce body fat and that it may curb appetite and increase the feeling of fullness.
Some studies have also suggested that it may have a favourable effect on blood glucose, cholesterol levels and blood pressure, although the evidence is still limited.
However, because its pH is between 2 and 3, it can irritate the stomach and the oesophagus.
In fact, a case report published in 2020 described a 75-year-old woman who developed septic shock after damage to the lining of the oesophagus and had to undergo surgery 3 times. The habit of drinking vinegar every day was reported to have caused this irritation.
In addition, it should be avoided by people with type 1 diabetes because it can worsen gastroparesis, which is common in type 1 diabetes. People with type 1 diabetes should be very careful about this and speak to their doctor first!
Although it may have some positive effects on weight control and on certain conditions, just as lemon water has no miraculous effects, you should not expect apple cider vinegar on its own to deliver them either.
Weight control and healthy blood values are best supported by building a lasting eating and exercise routine.
