MYTH: Sugar causes cavities
误解：糖导致蛀牙
FACT: Cavities are actually caused by acidic foods and drinks that wear away the enamel on your teeth.
事实：蛀牙实际上是由酸性食物和饮料导致的，酸性物质会腐蚀牙齿上的釉质。
"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."
“问牙医”网络社区的马克•布尔亨内医生说：“导致蛀牙的不是糖，而是酸。最容易导致蛀牙的食物是饼干和面包，不是糖。当你吃含糖食物时，口腔内的天然细菌也在‘吃糖’。细菌排出的废物是酸，所以在吃完饭后，细菌都会产生酸……这些酸性物质会腐蚀牙齿的外结构，从而使牙釉质脱落，导致蛀牙。”
MYTH: You should eliminate all sugar from your diet
误解：你应该完全不吃糖
FACT: Humans need glucose to survive.
事实：人类需要葡萄糖才能生存。
Of course, having too much sugar will lead to the problems we discussed above, like weight gain and long term health problems. But, glucose is essential to our body.
当然，吃太多糖会导致我们上面所说的问题，比如体重增加和慢性疾病。但是，葡萄糖对我们的身体至关重要。
"This idea that sugar is inherently bad for you is a myth," Dr. Haythe said. "We all need sugar; that's the basic block of what runs our bodies. It's necessary to survive.
海耶斯博士说：“糖对身体本质上不好是个误解。我们都需要糖，这是让人体运转的基本组成部分。糖是让我们存活的必需物质。”
