Another Reason to Hit the Dairy Aisle

Yogurt has been touted for boosting your immune system,
but there's another reason it may keep you smiling. A study
in the Journal of Periodontology found that people who consumed
2 ounces or more of lactic acid-rich foods, such as yogurt and
kefir, had a 60 percent lower risk for severe periodontal disease
than those who didn't eat any.
Left untreated, the dental
condition can cause bleeding, receding gums, and tooth loss.
Scientists once believed it was the calcium in dairy products that
fostered oral health, but now they say the effect may be attributed
to probiotics, beneficial bacteria found in foods with lactic acid.
Since dairy products made without probiotics, like milk and some
cheeses, don't provide the same protective effect, get at least half
of your dairy servings each day from yogurt.
