德国研发出防蛀牙糖果 牙齿越吃越健康
<p>德国柏林一家公司研发了一种防蛀牙糖果，这对那些喜欢吃甜食的人真是好消息。</p><p>这家公司指出，其实并不是糖果或者糖引起龋齿和蛀牙，而是牙齿表面正常的菌群在你吃过糖后会分泌酸，然后你的牙釉质就有了洞。正常的细菌中对你牙齿最有害的是变形链球菌，所以如果你能减少它们存在于你口腔里的量，你就能有效抑制龋齿的发生。</p><p>研究人员制造了一种无糖的糖果，其中含有一种能在口腔中减少变形链球菌的益生菌。在参与测试的60个志愿者中，有四分之三的人在吃过这个糖果一天后，口腔里的变形链球菌就显著减少了。</p><p><span word="It">It</span> <span word="may">may</span> <span word="sound">sound</span> <span word="too">too</span> <span word="good">good</span> <span word="to">to</span> <span word="be">be</span> <span word="true">true</span>, <span word="but">but</span> <span word="German">German</span> <span word="researchers">researchers</span> <span word="have">have</span> <span word="created">created</span> <span word="a">a</span> <span word="sugar">sugar</span>-<span word="free">free</span> <span word="candy">candy</span> <span word="they">they</span> <span word="say">say</span> <span word="can">can</span> <span word="actually">actually</span> <span word="fight">fight</span> <span word="cavities">cavities</span>.</p><p><span word="The">The</span> <span word="development">development</span>, <span word="reported">reported</span> <span word="by">by</span> <span word="Medical">Medical</span> <span word="News">News</span> <span word="Today">Today</span>, <span word="involves">involves</span> <span word="lacing">lacing</span> <span word="the">the</span> <span word="candy">candy</span> <span word="with">with</span> <span word="dead">dead</span> "<span word="good">good</span>" <span word="bacteria">bacteria</span> <span word="that">that</span> <span word="bind">bind</span> <span word="to">to</span> "<span word="bad">bad</span>" <span word="cavity">cavity</span>-<span word="producing">producing</span> <span word="bacteria">bacteria</span> <span word="in">in</span> <span word="the">the</span> <span word="mouth">mouth</span> <span word="to">to</span> <span word="block">block</span> <span word="tooth">tooth</span> <span word="decay">decay</span>.</p>
