Telling kids to go outside and play may be good for
their gums.
According to a study in the Journal of Periodontology, sunlight contributes to healthy teeth and
bones. Even a little bit of sun helps the body make
vitamin D. (Fifteen minutes twice a week to the face,
arms, hand or back is usually enough.) Vitamin D, in turn,
helps the body absorb calcium.
Too little vitamin D may be a risk
factor for periodontal disease. "Numerous studies
indicate that vitamin D and calcium deficiencies result in
bone loss and increased inflammation," said Dr. Charles
Hildebolt, Department of Radiology, Washington University
School of Medicine in St. Louis. "Inflammation is a
well-recognized symptom of periodontal diseases, which is
why it has been suggested that calcium and vitamin D
deficiency may be a risk factor for periodontal
diseases."
Scientists say that many infectious
diseases are linked with low levels of vitamin D. Vitamin
D suppresses production of proinflammatory cytokines,
which are molecules that have destructive effects
throughout the body.
"Periodontal disease increases the
production of cytokines, but it has been demonstrated that
vitamin D can suppress cytokine production, and possibly
decrease the risk of periodontal disease," said Dr.
Hildebolt.
Other sources of vitamin D include foods fortified with
the vitamin, including milk, eggs, sardines and tuna fish. |
