刷牙太少可能得肺病?这个新研究吓到我了
Previous studies had already indicated that clean teeth meant clean lungs, at least among the aged residents of hospitals and nursing homes. Microbes in saliva that's breathed in were the most likely source of pneumonia, but the identities of the top offenders were yet to be determined. "This bacterial group was more predominant in the elderly with fewer teeth, a higher plaque index, and more dental caries-experienced teeth," says Yamashita. Our relationship with our body's microflora has been the focus of a great deal of investigation in recent years. It's clear that our health is tightly bound with the precise make-up of fungi , viruses, and bacteria that populate our entire digestive system. |
