Eating in a shorter time window may help older adults keep their thinking skills sharp
A small study found that older women who ate only within a nine-hour window did better on some thinking tests than those who ate over a longer period, even though both groups lost the same amount of weight.
Many older adults worry about their memory and thinking skills. Scientists want to help people stay sharp as they get older. A new study looked at eating habits and the brain. Researchers led by Prof Sue Shapses at Rutgers University did this work. They worked with 47 women aged 50 to 79. All the women were overweight or had obesity. The study lasted for six months. Every woman cut 500 calories from her daily food. One group ate only in a nine-hour window, usually from 10am to 6pm. The other group ate over about 12 hours. Both groups lost about 7kg of weight. But the nine-hour group did better on some brain tests. They were stronger at spatial planning and problem-solving. They also made fewer errors on memory tests. There was no difference in reaction time. Dementia is a serious problem around the world. It causes nearly 2 million deaths each year. Experts say lifestyle changes can help prevent many cases. Obesity in middle age raises dementia risk by 30%. This study suggests that when you eat may matter for your brain. It may help older adults keep their thinking skills sharp. More research is needed to learn more.

许多老年人担心自己的记忆力和思维能力。科学家希望帮助人们在变老时保持头脑敏锐。一项新研究调查了饮食习惯与大脑的关系。由罗格斯大学的苏·夏佩斯教授领导的研究人员开展了这项工作。他们与47名50至79岁的女性合作。所有女性都超重或患有肥胖症。这项研究持续了六个月。每位女性每天减少500卡路里的食物摄入。一组人只在九小时内进食，通常是从上午10点到下午6点。另一组人在大约12小时内进食。两组都减掉了大约7公斤的体重。但九小时组在一些大脑测试中表现更好。他们在空间规划和问题解决方面更强。他们在记忆测试中犯的错误也更少。在反应时间方面没有差异。痴呆症是世界范围内的一个严重问题。它每年导致近200万人死亡。专家表示，生活方式的改变可以帮助预防许多病例。中年肥胖会使痴呆症风险增加30%。这项研究表明，你什么时候进食可能对大脑有影响。它可能帮助老年人保持思维能力敏锐。需要更多的研究来了解更多信息。
