科学家们表示，进食时更长时间的咀嚼食物或许能帮助你减轻体重。
Munching on each mouthful for longer significantly reduces the amount of calories consumed during a meal, a study found.
根据一份研究报告的显示，每一口食物咀嚼的时间更长的话，这将降低人体所吸收的卡路里热量。
Volunteers who chewed each mouthful 40 times ate 12 per cent less food than those who chewed just 15 times.
参加测试人中的一组每口食物咀嚼40次，另一组则只咀嚼15次，结果发现40次的这组要比15次的这组少吃掉百分之十二的食物。
It is thought chewing for longer prevents over-eating by giving the brain more time to receive signals from the stomach that it is full.
科学家们认为，更长时间的咀嚼食物能有效的防止过量进食，因为大脑有了更多的时间来从胃部接收到饱足感的“信号”。
It also appears to lower levels of ghrelin, the ‘hunger hormone’, circulating in the digestive system.
同时人体中一种在消化系统循环中被称为“饥饿激素”的物质的水平也有明显的下降。
Researchers at Harbin Medical University in China recruited 16 slim men and 14 obese men in their late teens or twenties and carried out two experiments.
中国哈尔滨医科大学的研究人员们召集了16名身材苗条和14名肥胖的男性进行了这两项试验，他们的年龄介于十几岁到二十几岁之间。
