In the 83rd General Session of the International Association for Dental Research held in Baltimore, US, Japanese scientists have presented the results of a study that says eating sugar-free yogurt is good for people suffering from bad breath.
Oral bad odor or so called bad breath is caused by harmful bacteria and sulfide compounds like hydrogen sulfide. The study revealed that volunteers who had sugar-free more and natural form of yogurt for six weeks reported of lessening of mouth odor. There was a reduction of 80% of the volatile hydrogen sulfide in the mouth cavity. Also, the plaque and gingival indices were at considerable low for volunteers who have had yogurt versus those with bad breath who didn't.
The reason for this may be due to the bacteria present in the yogurt called lactobacillus bulgaricus and streptococcus thermophillus who wedges a war against the harmful and odor causing bacteria and chemicals in the mouth.
The researchers are of the opinion that eating traditional yogurt or curd may help in oral hygiene by reducing oral bad breath and harmful bacteria.
The scientists of the Tsurumi University, Yokohama, Japan, conducted the research
