The study appears in the Journal of Periodontology . It was conducted by
researchers including Nabil Bissada, DDS, chairman of the periodontics
department at Case Western Reserve University School of Dental Medicine.
Healthy Body, Healthy Mouth
Data came from a national health survey of more than 12,000 people. The
findings:
-
Having all three traits -- normal weight, good diet, active lifestyle -- cut
gum disease risk by 40%.
-
Having two of those habits cut gum disease risk by 29%.
-
Having one of those healthy habits cut gum disease risk by 16%.
Gum disease was rarest among people with all three traits. Only 7% of them had
gum disease, compared with 18% of those with none of those traits.
Benefits for the Mouth
Why did the mouth mirror overall health? The researchers note these
possibilities:
-
Healthy foods such as fruits and vegetables may help clear plaque off teeth.
-
Obesity may promote inflammatory chemicals linked to gum disease.
-
Physical activity may cut inflammation, helping the entire body (including the
mouth).
Go-for-It Goals
Here's how the researchers defined their terms:
-
Moderate-intensity physical activity at least 5 times per week or vigorous
intensity activity at least 3 times per week
-
Normal BMI (body mass index) of 18.5 to 24.9
-
High score on an index of healthy foods eaten over the past day
Moderate-intensity physical activity would include activities such as walking at
a moderate or brisk pace of 3 to 4.5 miles per hour on a level terrain.
Vigorous-intensity physical activity includes race walking or aerobic walking
at 5 miles per hour or greater, jogging, or running. According to the CDC, in
general activities in the moderate-intensity range would require 25-50 minutes
to expend a moderate amount of activity, and activities in the
vigorous-intensity range would require less than 25 minutes to achieve a
moderate amount of activities.
Participants reported their own weight, activity level, and food habits. That
leaves a little wiggle room about accuracy. Plus, the study was a one-time
snapshot, not a long-term look at health.
Still, the basics -- move more, ditch excess weight, and make good food choices
-- are widely recommended as staples of a healthy life.
Brushing and flossing your teeth may also boost your heart health, boost your
heart health, as researchers reported in February.
Bucking the Trend
Most people didn't ace all three areas.
"Only about 3% of the entire group maintained normal weight, engaged in the
recommended level of exercise, and had a high-quality diet," write the
researchers. They note that more than three out of 10 participants didn't
report any of those habits.
But, the future doesn't have to mirror the past or present. Change is always
possible. To kick-start the process, check in with a doctor and seek whatever
support or training you need.
