Transcript

 

 This is Scientific American's 60-Second Science. I'm Karen Hopkin. This will just take a minute.

 

You may have noticed that as you get older, you start forgetting more stuff: like, where you left your glasses, or the names of your children. Well, if you’re fed up with those senior moments, put down that pastrami sandwich. Because a new study, published in the January 27th issue of the Proceedings of the National Academy of Sciences, shows that cutting calories actually improves memory in older folks.

Calorie restriction lets lab animals live longer. And these hungry critters tend to be healthier, too: with lower cholesterol, better insulin sensitivity, and even slower cognitive decline. But these diets can be draconian. And it hasn’t been clear whether they’d offer the same benefits to people.

In this study, scientists asked 50 elderly women to cut the number of calories they consumed by a third. After three months, the researchers found that the dieters were not only slimmer, but they were better than they had been at memorizing lists of words. They also had better insulin levels and fewer markers of inflammation, which suggests that keeping those things under control may help keep the brain fit. It’s one of the cruel ironies of aging: if you want to remember your favorite restaurants, the less you should eat at them.

 

Thanks for the minute for Scientific American's 60-Second Science. I'm Karen Hopkin.

You may have noticed that as you get older you start forgetting more staff, like where you left your glasses or the names of you children. Well, if you're fed up with those senior moments, put down that pastrami sandwich. Because a new study published in the January 27th issue of the Proceedings of the National Academy of Sciences shows that cutting calories actually improves memories in older folks.

 

Calorie restriction lets lab animals live longer. These hungry critters tend to be healthier too. With lower cholesterol, better insulin sensitivity and even slower cognitive decline. But these diets can be draconian and it hasn't been clear whether they offer the same benefits to people.

 

In this study, scientists asked 50 elderly women to cut the number of calories they consume by 1/3. After 3 months, the researchers found that dieters were not only slimmer but they were better than they had been in memorizing lists of words. They also at better insulin levels and fewer marks of inflammation, which suggest that keeping those things under control may help keep the brain fit. It's one of the cruel irony of agingif you want to remember you favorite restaurants, the less you should eat at them.
