A humble bottle of vinegar comes with a long list of health claims. Folklore and anecdotal evidence claims that vinegar is the cure for lice, kidney disease, alcoholism, hypertension, jelly fish stings, tumors, ear infections and many more ailments and nuisances. Unfortunately, many of vinegar’s health claims cannot be backed with scientific evidence.
However, vinegar is an important and affordable ingredient to keep stocked in your kitchen. Some studies suggest that vinegar may help to control blood glucose levels in healthy and insulin-resistant individuals. Controlling blood glucose levels is important for long-term health in all individuals, not only those with diabetes. Vinegar is also a source of polyphenols, plant compounds that act as antioxidants in humans. Antioxidants protect the body from damaging free radicals. Another study suggests that vinegar may help people feel full longer, leading to fewer calories ingested, which may lead to weight loss over time. Generally vinegar is safe to ingest, when using in typical cooking amounts or diluted with water if ingested separately from meals. Vinegar supplements are not recommended due to the risk of esophageal burning.
