咀嚼瘦身效果堪比减肥药

Chewing your food for longer may help you lose weight, scientists have suggested. Munching on each mouthful for longer significantly reduces the amount of calories consumed during a meal, a study found. Volunteers who chewed each mouthful 40 times ate 12 per cent less food than those who chewed just 15 times. 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. 不用再花钱请私人健身教练,不必再吞下昂贵的减肥产品，专家近日调查得出结论：咀嚼食物时间长，可以达到非常好的减肥效果。专家称，长时间的咀嚼食物可以相当程度地降低食物中的卡路里含量，数字现实，每次咀嚼食物达到40下，相对每次咀嚼食物仅仅为15下的情况，卡路里能减少12%。此外，还有一种说法，咀嚼的时间越长，留给大脑思考的时间就会越多，人们会时刻意识到：哦，差不多了，胃快要到达极限了，还是停下来吧！

It also appears to lower levels of ghrelin, the ‘hunger hormone’, circulating in the digestive system. 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. In the first, they wanted to see if the obese men chewed their food differently to their lean rivals.

据悉，长时间的咀嚼可以达到减肥的效果这一理论和----胃饥饿素（一种胃肠道激素）的水平高低有关系。胃饥饿素（一种胃肠道激素）也被称作生长素(Ghrelin)是一种主要由胃黏膜分泌的,作用于内源性生长激素促分泌剂受体,通过加快胃排空调节食欲,抑制体质量.

In a report on their findings, published in the American Journal of Clinical Nutrition, the researchers said eating more slowly could be a simple and effective way of tackling weight problems. They said: ‘Research indicates eating quickly, gorging and binge eating have a substantial effect on being overweight.‘Our results showed obese participants chewed less and ingested more quickly than lean ones. ‘

这项研究已经发表在《美国临床营养学杂志》上，资料显示，咀嚼次数多，并且时间长，是一种很有效的减肥方式。专家说：“研究显示，吃饭太快，甚至暴饮暴食对于体重的增加有着不可推卸的责任。我们发现，那些体重过胖的人，咀嚼次数比普通人要少。”

A survey of 1,000 people last year by the sandwich chain Subway showed the average person in Britain chews their food just six times before swallowing it. Young, busy professionals in the 25-34 age group were the worst culprits.

The same survey found 15 per cent of people regularly ate a meal while walking and only half routinely sit down to eat at a table.

据悉，在针对在全球快餐连锁店Subway吃三明治的1000名食客的调查中发现，英国人平均在吞咽前咀嚼食物的次数仅仅为6次，而且，在那些25到34岁之间的工作狂白领来说，他们属于咀嚼次数最少的一部分人群。此外，数据显示，有15%的人喜欢边走路边吃东西，只有50%的人愿意正儿八经地坐在桌子旁边吃饭。

Catherine Collins, chief dietician at St George’s Hospital, London, said although eating more slowly may have some effect on gut hormone levels, the benefits are more likely psychological.‘When you gulp down your food, you don’t realise you’re eating so much.‘But chewing for longer makes you more likely to notice the taste, smell and texture, which makes you more aware of what you’re eating and how much. ‘As a result, you’re less likely to feel hungry again ten minutes later.’
