Eating yogurt and other foods laden1 with lactic2 acid may keep your gums from receding3 and teeth from falling out, Japanese researchers report.
"But, milk and cheese were not," Shimazaki said.
Periodontal disease is a chronic4 bacterial5 condition associated with receding gums and tooth loss. Outside of regular brushing and flossing, effective measures to allay6 this disease are limited, Shimazaki, of Kyushu University in Fukuoka, Japan, and colleagues note in the Journal of Periodontology.
Previous research identified a lower occurrence of periodontal disease among people who eat high amounts of dairy products, but did not identify which dairy products were most beneficial, the researchers report.
They found that people with generalized (more advanced) periodontal disease had a lower intake of lactic acid foods than people with localized (less advanced) periodontal disease.
Compared with individuals reporting no lactic acid food intake, those eating 55 grams or more of yogurt (half an 6-ounce carton) or lactic acid drinks a day had significantly fewer markers of severe periodontal disease. The investigators9 made allowances for factors such as age, gender10, smoking, alcohol intake, frequency of tooth brushing, blood sugar and cholesterol11 levels.
