Apple cider vinegar is a type of vinegar made with crushed fermented apples, yeast, and sugar. Its used as an ingredient in foods such as salad dressings, pickles, and marinades, and people have also used it as a home remedy for everything from fighting germs to preventing heartburn. While theres not a lot of evidence for these benefits, ACV is generally harmless – as long as you use it correctly. Here are some of the potential health benefits of drinking apple cider vinegar, backed by science:

• May help with weight loss: Some studies have shown that taking apple cider vinegar twice a day helped people following a reduced-calorie diet lose a few extra pounds. However, the studies were small and short-term, so more research is needed to fully understand this link.

• May lower cholesterol: One small study found that apple cider vinegar lowered the total cholesterol levels of study subjects who took it. It also increased their "good" cholesterol and lowered levels of triglycerides (fats in the blood) . Other studies have had similar findings, but experts caution that we need more research to fully understand this link.

• May help with blood sugar control: Research has shown that consuming acetic acid—the active ingredient in ACV—affects the way starches are broken down during digestion. The delayed absorption of sugar from carbohydrates improves the insulin response to blood sugar and thus promotes better blood sugar control. However, more research is needed to fully understand this link.

• May have antimicrobial effects: Vinegar can help kill pathogens, including some strains of bacteria. Specifically, ACV may be effective in inhibiting the growth of Escherichia coli, Staphylococcus aureus, and Candida albicans.

Its important to note that consuming too much apple cider vinegar can cause irritation of the esophagus, erode tooth enamel, and decrease potassium levels. Those taking diuretics and/or insulin should consult their doctor before changing any dietary practices. Overall, ACV is safe, but its always a good idea to talk to your doctor before trying any new home remedies or supplements.
