As we grow older, our bodies, including our brains, naturally age. The things our brain does, like remembering stuff and learning new things, start to slow down.
Some smart people who study this stuff found out that if we live a healthy life, it can slow down the aging of our brains. The National Institute on Aging says that things like moving around, dealing with stress, having friends, and eating good food can help keep our brains in good shape.
Now, there are some scientists at the Buck Institute for Research on Aging in Novato, CA, who found something interesting. They say that not eating too much food might also help our brains stay young. They checked this idea using tiny fruit flies and some human cells.
These scientists shared their findings in a journal called Nature Communications. They found a special gene that gets better when we eat less, and it helps our brains age in a healthy way. So, it seems like eating a bit less could be another way to keep our brains in good shape as we get older.
