1.High in healthful substances

Apple cider vinegar is made via a two-step process .

First, the manufacturer exposes crushed apples to yeast, which ferments the sugars and turns them into alcohol.

Next, adding bacteria further ferments the alcohol, turning it into acetic acid — the main active compound in vinegar.

Acetic acid gives vinegar its strong sour smell and flavor. Researchers believe this acid is responsible for apple cider vinegar’s health benefits. Cider vinegars are 5–6% acetic acid.

2.Can help kill harmful bacteria

Vinegar can help kill pathogens, including bacteria.

The main substance in vinegar — acetic acid — can kill harmful bacteria or prevent them from multiplying.

People have traditionally used vinegar for cleaning and disinfecting, treating nail fungus, lice, warts, and ear infections.

Vinegar is also a food preservative. Studies show that it inhibits bacteria like E. coli from growing in and spoiling food.

3.May help lower blood sugar levels and manage diabetes

To date, one of the most convincing applications of vinegar is helping treat type 2 diabetes.

The most effective and healthiest way to regulate blood sugar levels is to avoid refined carbs and sugar, but apple cider vinegar may also have a beneficial effect.

Apple cider vinegar has shown great promise in improving insulin sensitivity and helping lower blood sugar responses after meals.

4.May aid weight loss

Perhaps surprisingly, studies show that vinegar could help people lose weight.

Several human studies show that vinegar can increase feelings of fullness. This can lead to eating fewer calories and losing weight.

Apple cider vinegar only contains about three calories per tablespoon, which is very low.

5.May boost skin health

Apple cider vinegar is a common remedy for skin conditions like dry skin and eczema.

The skin is naturally slightly acidic. Using topical apple cider vinegar could help rebalance the natural pH of the skin, improving the protective skin barrier .

6.Improves heart health in animals

Heart disease is one of the leading causes of death.

These animal studies suggest that apple cider vinegar can lower cholesterol and triglyceride levels, as well as several other heart disease risk factors.

Some studies in rats have also shown that vinegar reduces blood pressure, which is a major risk factor for heart disease and kidney problems.

However, there is no good evidence that vinegar benefits heart health in humans. Researchers need to do more studies before reaching any strong conclusions.
