益生菌帮你对抗感冒发烧

New evidence suggests that probiotics -- good bacteria that can aid immune function -- can have a preventive effect for cold and flu viruses.

最新证据表明，有益菌能帮助免疫系统提高技能，从而有效对抗发烧和流感病毒。

In a study sponsored by Danisco, a Danish nutritional supplement company that makes probiotics products, researchers found that a six-month course of probiotics was a safe and effective way to ward off flu symptoms and reduce their duration in 3- to 5-year-olds.

在由丹麦的一家营养补充企业Danisco赞助的这项研究中，研究人员发现，对于3到5岁的儿童来说，要扫除流感症候并加快痊愈，连续六个月服用益生菌是安全又有效的方法。

Nearly 250 kids were treated twice daily for six months. One group of children received a single strain of the probiotic called Lactobacillus acidophilus, one group received a combination of the L acidophilus and Bifidobacterium probiotics, and a third group received a placebo.

大约250名儿童参与了实验，在六个月中每天接受两次益生菌。一组儿童接受的单一的一种益生菌，另一组接受的是两种益生菌的组合，第三组接受安慰剂作为对照。

Compared to the placebo group, the single and combination probiotics had reduced fever incidence by 53 percent and 72.7 percent, respectively, decreased coughing by 41.4 percent and 62.1 percent, and reduced runny noses by 28.2 percent and 58.5 percent.

相比起第三组，服用单一益生菌和服用组合益生菌的小组里，儿童的流感发生率分别少了53%和72.7%，咳嗽发生率减少了41.4%和62.1%，流涕症状减少了28.2%和58.5%。
