Ⅰ. 阅读理解 Watching what yu eat can be easier said than dne, but a recent study shws it might nt just be abut what’s n yur plate—it culd be abut hw quickly it disappears. Japanese researchers fllwed 1, 083 adults fr five years, splitting them int three categries based n hw quickly they ate: slw, nrmal, and fast. They als answered a questinnaire at the beginning f the study, sharing their diet, physical activity, and medical histry. In the beginning, nne f the vlunteers had metablic syndrme(新陈代谢综合征)—meaning at least three risk factrs— which can lead t health prblems like heart cnditins and diabetes.
When the participants reprted back five years later, 84 had been diagnsed (诊断) with metablic syndrme—and their eating speed was a majr predictr, accrding t the results in the jurnal Circulatin. The fast eaters were 89 percent mre likely t have metablic syndrme than slw and nrmal eaters. Just 2. 3 percent f slw eaters received the diagnsis, cmpared t 11. 6 percent f fast eaters. But that’s nt all. Fast eaters als saw mre weight gain, larger waistlines, and higher bld sugar levels than slw eaters.
The researchers say gbbling makes it easier nt t take ntice f fullness befre yur bdy has a chance t signal yu t stp. “S when peple eat fast they are mre likely t vereat, ” said Takayuki Yamaji, MD, study authr and cardilgist at Hirshima University in Japan in a statement.

One study f New Zealand wmen fund fast eaters have higher bdy-mass indexes (指数), and a Chinese study fund that bth healthy and fat men ate less when tld t chew 40 times instead f 15 times befre swallwing. Initial research even suggests chewing yur fd lnger culd burn mre calries—up t abut 1, 000 extra every mnth.
