Some research suggests that consuming apple-cider vinegar after a meal can decrease blood-sugar levels by altering the way a person’s food is absorbed from the gut. However, there is not enough evidence to support this benefit as of 2015, reports WebMD.
Apple-cider vinegar is the juice of crushed, fermented apples. It contains many nutrients, including biotin, B vitamins, folic acid, niacin and vitamin C. It can be used to treat arthritis, osteoporosis, a sore throat and upset stomach. It can also aid in weight loss. It can be applied to the skin for acne, insect bites, shingles or sunburn, notes WebMD.
