Dental Research
Sugarless yoghurt could help beat bad breath, tooth decay and gum disease, say scientists. Japanese researchers found eating the yoghurt reduced levels of hydrogen sulphide, a major cause of bad breath, in 80% of volunteers. The key are active bacteria in yogurt, specifically Lactobacillus bulgaricus and Streptococcus thermophilus. Details were presented at a meeting of the International Association for Dental Research. A total of 24 volunteers who took part in the study were given strict instructions on oral hygiene, diet and medication intake. They spent two weeks avoiding yoghurts and similar foods, like cheese.
