Scientists from Corneli University have found that many copies of the Amy1 gene have the danger of toothpaste due to the use of foods containing starch, such as potatoes, bread and corn. The results of the study were published in the Microorganisms magazine.
Scientists have gathered saliva samples from 31 people whose Amy1 has been different copies in DNA, and they have added starch to see how bacteria have changed. It turned out that while wearing a few example of Amy1, the Osla significantly reduces the amount of two bacteria, the atopobium and the Weilonella, while Streptococci's share increases.
According to researchers, all three types of bacteria are connected with the diseases of the mouth, but the main role in caries plays the main role in the streptocok.
It is noted that the microbomom of the oral cavity has developed with the increase in the number of duplicates of Amy1. Many examples of this gene have been found in populations with a long history of starch.
Scientists have explained that the backup of Amy1 helps to effectively disrupt the starla, getting more nutrients from these carbohydrates. However, this "sensitivity" leads to the increase in the population of Streptococi, which feeds on sugars contained in Osla.
