伦敦（路透社）--日本研究人员周三称，吃的很快直到吃饱的人肥胖的几率是普通人的三倍，这一问题因快餐的供应和规律性饮食习惯的下降而加剧。
这些发表在英国医学期刊的研究结果突出怎样的饮食风格，而不仅仅是吃什么或吃多少，会导致世界许多地方因西式风格的推动而使肥胖病流行。
世界卫生组织（WHO）将4亿人口列为肥胖，其中2千万在5岁以下。这一状况增加了2型糖尿病和心脏病的风险。
该研究中，大阪大学的Hiroyasu Iso及其同事调查了3千多名30～69岁之间的志愿者的饮食。大约一般的男性和一半稍过的女性说他们会一直吃到饱。约45%的男性和36%的女性说他们吃的很快。
研究人员发现，那些吃得快直到吃饱的人患肥胖的几率是不会吃到饱和吃得不快的人的三倍。
他们列举的原因包括廉价食物的大量供应和吃的时候看电视等习惯。
研究发现，为了抵制易于肥胖的儿童吃的快或狼吞虎咽的“超加性效应”，家长应鼓励他们在平静的环境中慢点吃。
Speedy eaters seen likelier to get fat
LONDON (Reuters) - People who eat quickly until full are three times more likely to be overweight, a problem exacerbated by the availability of fast food and the decline of orderly dining habits, Japanese researchers said on Wednesday.
The findings, published in the British Medical Journal, highlight how eating styles, and not just what or how much is eaten, can contribute to an obesity epidemic fueled by the spread of Western-style affluence in many parts of the world.
The World Health Organization classifies around 400 million people as obese, 20 million of them under the age of five. The condition raises the risk of diseases like type 2 diabetes and heart problems.
For their study, Hiroyasu Iso and colleagues at Osaka University asked more 3,000 Japanese volunteers aged 30 to 69 about their eating. About half of the men and a little more than half of the women said they ate until full. About 45 percent of the men and 36 percent of the women said they ate quickly.
Those who said they ate until full and ate quickly were three times more likely to be fat than people in the "not eating until full and not eating quickly" group, the researchers found.
They cited as causes both the availability of cheap food in big portions and habits like watching television while eating.
To counteract the "supra-additive effect" of speedy or glut eating among children prone to obesity, parents should encourage them to eat slowly and in calm surroundings, the study found.
