More Benefits of Probiotics

The study discussed in article posted below links the use of yogurt, and specifically lactic acid and probiotics, to improved mouth and gum health. The benefits of probiotics has long been recognized in the intestinal tract, but this study gives encouraging evidence that these useful bacteria can give a boost to other bodily functions as well.

This discovery is really no surprise. By improving the health of the gut, probiotics increase the overall effectiveness of the immune system and thus provide greater defenses against disease throughout the body. Yogurt is a wonderful source of natural probiotics as long as you choose organic yogurt with live, active cultures that does not include added sugars, preservatives, or other chemicals. Many health-conscious people also include a quality probiotic supplement in their wellness routine due to its many healthful advantages.


Yogurt may take bite out of gum disease
But researchers can't say the same about the benefits of milk, cheese

Regularly eating yogurt and other foods with lactic acid may be good for your mouth, Japanese researchers report.

Dr. Yoshihiro Shimazaki and colleagues found that consuming yogurt and lactic acid drinks was significantly associated with better periodontal health.

"But, milk and cheese were not," Shimazaki said.

Periodontal disease is a chronic bacterial condition associated with receding gums and tooth loss in adults. Outside of regular brushing and flossing, effective measures to allay 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.

Shimazaki's team assessed the severity of periodontal disease in 942 men and women, aged 40 to 79 years, and their intake of milk, cheese, and lactic acid foods.

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.

A carton a day may helpCompared with individuals reporting no lactic acid food intake, those eating 55 grams or more of yogurt or lactic acid drinks a day had significantly fewer markers of severe periodontal disease. (That's less than half an average 6-ounce carton of yogurt.) The investigators made allowances for factors such as age, gender, smoking, alcohol intake, frequency of tooth brushing, blood sugar and cholesterol levels.

"The beneficial effect on periodontal disease might be based on the probiotic effect of lactobacilli found in lactic acid foods," Shimazaki said. Probiotics are living microorganisms, such as the Lactobacillus bacteria in yogurt that are beneficial to one's health.

More study neededThe investigators suggest follow up studies that further analyze the probiotic effect of lactic acid foods by assessing the distribution of lactic acid bacteria in subjects' mouths based on the lactic acid foods they eat. Future research should also examine whether continuing intake of lactic acid foods alters the progression of periodontal disease.
