科学家称吃鼻屎可能有助增强免疫力
2013-10-15 中新网
据“中央社”报道,加拿大萨斯克其万大学(University of Saskatchewan)生物化学副教授纳柏(Scott Napper)说,最令人讨厌的坏习惯,挖出并吃掉鼻屎,可能对健康有益。
加拿大电视公司(CTV)报导,纳柏指出,几乎大部分的小孩都有股冲动,想要尝尝从鼻子挖出来的东西。他说,人类可能自然而然会做出这种行为,因为这对人类有益。
纳柏说,鼻内黏液可困住细菌,防止细菌进入肺部,不过,如果我们吃鼻屎,让身体接触到那些细菌,实际上可能有助于增强人体免疫力。
他告诉加拿大电视公司萨斯卡东新闻(CTV Saskatoon News):“这可以训练我们的免疫系统,知道可能会接触到什么东西,所以,这几乎是一种天然的疫苗接种。”

If you don’t like gross things, this story is snot for you.
An associate professor of biochemistry at the University of Saskatchewan is trying to get more students interested in science by looking at the health benefits of picking your nose and eating it.
Scott Napper says nature pushes us to do different things because it is to our advantage to have certain behaviours, to consume different types of foods.
Napper says mucous traps germs and stops them from getting into our body, but if we consume that mucous, it could help train our immune system by exposing it to the germs.
So he says when children have the urge to pick their nose and eat it, parents shouldn’t get upset.
Napper says he hopes to conduct a study where some type of molecule is inserted in people’s noses and then half the participants pick their nose and eat it and the other half don’t.
“I think the challenge would be getting volunteers to participate in this experiment,” he says with a laugh. “Especially if you didn’t know which group you were going to fall into.”
Napper also says making science more humorous and fun keeps students interested and engaged.
“I don’t try to convert them all to biochemistry. My goal is always if I can teach you one thing that you’re going to tell somebody else about outside the scope of this class, then I’ve prompted you to think a little bit, to question these things and I think with this example, it probably succeeded in that.”
Napper has two young daughters and says the idea of letting them pick their noses, even if in the name of science, didn’t go over well with his wife.
“Yeah, she’s of a different opinion,” he says. “She’s more towards training them to be little ladies.”
