Unfortunately, halitosis (aka bad breath) gets worse as we get older—but mints aren’t the only cure. “Lettuce, often thought as being the least nutritious vegetable, may be one of the easiest and most effective tools you have at your fingertips to fight dragon breath,” says Grotto. Instead of toting around a box of Altoids, just eat a salad for lunch. (But FYI: nibbling on lettuce isn’t a substitute for brushing and flossing, and trust us—you want to maintain a good oral hygiene regimen. A recent Turkish study showed that guys with gum disease are three times more likely to suffer from erectile dysfunction!)
