Some ingredients in coffee can suppress halitosis

Previously, it was generally believed that drinking coffee would make you have a bad breath. In fact, when coffee is mixed with milk, it dehydrates inside the mouth and ferments to produce odorous substances. The team chose two types of Arabica coffee and put them in a glass tube filled with saliva. They initially hoped the experiment would prove that coffee mixed with saliva produces foul-smelling gases.

The results of the experiment were unexpected. The researchers found that coffee can prevent the production of "stench", and in some experiments, coffee can reduce the production of "stench" by 90%. "We predicted that coffee would cause bad breath, but in fact, in this magical brewing process, some ingredients in coffee were found to suppress halitosis," the researchers said. "

Scientists believe that bad breath is inevitable, and even the healthiest bodies wake up in the morning with bad breath. The tongue and alveoli inside the mouth are the "paradise" of dental plaque. This kind of 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.

The researchers plan to isolate the magic substance that suppresses bad breath in coffee and believes it can inhibit the formation of dental plaque and block the occurrence of bad breath at the source. It may replace mint, which can only cover breath, and become the basic ingredient of a new generation of mouthwash, breath freshener and chewing gum. On the other hand, traditional mouthwash and chewing gum can only be temporarily covered but can not completely eliminate halitosis.
