Can apple cider vinegar help you lose weight? Maybe, if you're happy losing a third of a pound a week. That's the maximum benefit found in <a href="https://www.ncbi.nlm.nih.gov/pubmed/19661687" target="_blank">one study</a> of 175 overweight but otherwise healthy Japanese subjects. <br /><br />Other studies suggest that it can help you feel full, but so does the glass of water you dilute it in.

Looking to control your high blood sugar? Try vinegar before a starchy meal. The acetic acid helps block the absorption of starch, easing that after-meal spike. Pre-diabetics get the most benefit, says registered dietitian Carol Johnston, who has studied vinegars for years.

Some people suggest dabbing a bit of apple cider vinegar on acne or using it to fight skin aging. <br /><br />"It will dry out a pimple, but it's not an anti-aging method," says dermatologist Dr. Marie Jhin, a spokeswoman for the American Academy of Dermatology. "It might fade dark spots, or maybe you could use it as a skin toner, if you dilute it a great deal. But I wouldn't recommend it. We have much more effective and safe methods today than this."

Some people claim that apple cider vinegar can soothe a sore throat. Although there's no scientific evidence either way, American Academy of Pediatrics spokeswoman Dr. Jennifer Shu urges caution.<br /><br />"I would just think that the vinegar would irritate the throat even more," says Shu, an Atlanta pediatrician. "But diluting it or mixing it with other ingredients such as salt or honey might decrease any pain that the vinegar might cause."

Chicago dentist and American Dental Association spokeswoman Alice Boghosian isn't keen on the idea of rinsing, brushing or cleaning a toothbrush or dentures with apple cider vinegar. <br /><br />"You're putting acid on your teeth ... the last thing you'd want to do to promote oral health," she explains. "Anything acidic which contacts your teeth will wear out the enamel, the protective coating, and that will cause cavities."

Another popular use for apple cider and other vinegars is as a food wash to reduce the number of bacteria or virus on fruits or vegetables. <br /><br />"Vinegar and lemon juice have potential as inexpensive, simple household sanitizers," the FDA says. "However, possible negative sensory effects when used on produce would be a disadvantage."

Apple cider vinegar is great on alkaline grime, such as hard water mineral deposits and soap scum. But it doesn't cut grease and isn't as effective as commercial cleaners on E. coli or common staphylococcus bacteria.
