A new study finds that people who chew their food more take in fewer calories, which may help them control their weight, Reuters reported.

Chewing food 40 times instead of a typical 15 times caused study participants to eat nearly 12 percent fewer calories, according to results published in the American Journal of Clinical Nutrition.

Jie Li and colleagues from Harbin Medical University in China did the research.

The team found more chewing was associated with lower blood levels of ghrelin, a hormone that stimulates appetite, as well as higher levels of CCK, a hormone believed to reduce appetite. (点击路透社网站查看原文)

嚼得多 吃得少

       据路透社报道,一项新的研究发现人们吃东西时如果咀嚼的次数多,摄入的卡路里就少,这种方法可以帮助人们控制体重。

       一般情况下人们咀嚼食物15下之后吞咽,但同样的食物研究对象在咀嚼了40下之后再吞咽,他们摄入的卡路里数量就减少了12%。

       这一研究是由哈尔滨医科大学的李杰(音)和他的同事共同完成的,研究结果发表在《美国临床营养学杂志》上。

       李杰的团队发现多咀嚼会降低胃饥饿素的水平,同时还会提高胆囊收缩素的水平。胃饥饿素是一种提高食欲的激素而胆囊收缩素则可以降低食欲。
