Can Sugar-Free Gum Actually Prevent Cavities? [The New York Times] Sure, popping a piece of sugar-free gum can seem like a smart post-meal option when a toothbrush isn’t available. But do the products really prevent cavities? Not exactly, says most research into the claim, including a major new study published in The Journal of the American Dental Association. Instead, the actual act of chewing the gum—which increases the flow of saliva, thereby rinsing away plaque and debris—seems to confer that benefit. Of course, these findings don’t mean you should sacrifice a chew here and there. But researchers caution that gum chompers should always opt for sugar-free varieties, because gum made with sucrose will do your teeth much more harm than good.

Writing in the Journal of Consumer Research, investigators conclude that people are less likely to get a flu shot when the injection costs more, because they assume that a higher price means they’re less vulnerable to the illness.
