Eating more soy and isoflavone-containing foods regularly may confer an individual with significant protection against periodontal disease.
This study investigated the correlation between regular intake of soy and isoflavone-rich foods and the likelihood of being diagnosed with periodontal disease. Researchers analyzed data from 3,956 Japanese female students within the age bracket of 18-22 years who responded to questionnaires on their eating habits.
The team of investigators observed that the risk of having periodontal disease was lower in high consumers of soy and isoflavones than in subjects who did not eat these foods. "Our findings suggest that soy and isoflavone intake may decrease the likelihood of periodontal disease," the researchers concluded.
