不敢吃糖？科學(xué)家揭示人們對(duì)糖的8個(gè)誤解

MYTH: Sugar causes cavities
誤解：糖導(dǎo)致蛀牙

FACT: Cavities are actually caused by acidic foods and drinks that wear away the enamel on your teeth.
事實(shí)：蛀牙實(shí)際上是由酸性食物和飲料導(dǎo)致的，酸性物質(zhì)會(huì)腐蝕牙齒上的釉質(zhì)。

"Sugar isn’t the cause of tooth decay; acid is," Dr. Mark Burhenne, of the online "Ask a Dentist" community, said. "The most cavity-causing food is crackers and breads, not candy. When you eat something with sugar, bacteria that naturally reside in your mouth consume this sugar as well. Bacteria’s waste product is acid, so after they have a meal, they excrete acid....Acid decalcifies or demineralizes tooth enamel by taking away its structure, creating decay."
“問(wèn)牙醫(yī)”網(wǎng)絡(luò)社區(qū)的馬克?布爾亨內(nèi)醫(yī)生說(shuō)：“導(dǎo)致蛀牙的不是糖，而是酸。最容易導(dǎo)致蛀牙的食物是餅干和面包，不是糖。當(dāng)你吃含糖食物時(shí)，口腔內(nèi)的天然細(xì)菌也在‘吃糖’。細(xì)菌排出的廢物是酸，所以在吃完飯后，細(xì)菌都會(huì)產(chǎn)生酸……這些酸性物質(zhì)會(huì)腐蝕牙齒的外結(jié)構(gòu)，從而使牙釉質(zhì)脫落，導(dǎo)致蛀牙。”
