Israel: Study finds coffee can effectively curb bad breath

Coffee contains substances that inhibit bad breath and may be used in mouthwash, breath fresheners or gum to keep your breath fresh, according to a new study by Israeli scientists.

Professor Mel Rosenberg, a tone expert at Tel Aviv University in Israel, accidentally discovered this magical effect of coffee in an experiment. Rosenberg's team selected two Israeli-made coffee and one instant coffee and put them in a glass tube filled with saliva.

The researchers found that coffee can prevent 90% of the "stench". "We often say that coffee causes bad breath, but it turns out that some ingredients in coffee can suppress bad breath," Rosenberg said. "

The tongue and alveoli inside the mouth are the "paradise" of dental plaque. This bacteria can produce volatile sulfur compounds that make the mouth stink. If you eat strong foods such as onions and garlic, bad breath will last for a long time. Because the blood will absorb these food ingredients, then enter the lungs, and then exhale.

Rosenberg plans to separate the magic substance that suppresses bad breath in coffee to replace mint, which can only cover breath, as the basic ingredient of a new generation of mouthwash, breath freshener and chewing gum.

Wang Xingguo, executive director of the Dalian Nutrition Society, said that drinking some coffee properly does have the effect of preventing and removing breath. Like tea, it contains some chemicals that remove breath. In addition to drinking, you can also gargle with coffee, which is equally effective.
