There’s been a lot of talk about how what we eat affects our bodies, but did you know it can also impact your brain?
Yes, you heard that right. The types of food you eat, especially as you get older, can play a big part in how well your brain works and even in how long you live.
Scientists have been saying for a while now that eating too much junk food—stuff that’s high in fat and sugar—might not be the best for your brain. It can make your brain not work as well and might even lead to serious problems like Alzheimer’s disease.
But there’s one area that hasn’t gotten a lot of attention until recently: the difference between eating food that’s barely been touched and food that’s been heavily processed. You know, the kind of stuff that comes in boxes or bags with a lot of ingredients you can’t even pronounce.
Two big studies have just come out, and they’re saying that eating a lot of this heavily processed food might speed up the brain’s aging process and raise the risk of dementia.
However, another study says that for people over 60, eating these foods doesn’t seem to make their brain health worse.
Even though we need more studies to be sure, this is a big deal. It’s like adding another piece to the puzzle of how to keep our brains healthy as we get older.
When we talk about heavily processed foods, we’re talking about things like soda, packaged snacks, frozen meals, and fast food.
These items usually have less of the good stuff your body needs, like nutrients and fiber, and more of the not-so-good stuff, like sugar, fat, and salt.
But it’s important not to mix up heavily processed foods with processed foods, which might have gone through some changes but still keep most of their natural goodness. Think canned veggies, dried pasta, or frozen fruit.
The research looked at thousands of people and found that those who ate more heavily processed foods didn’t do as well on memory and thinking tests over time compared to those who ate less of these foods.
And in one of the studies, people eating the most processed food had a higher chance of getting dementia.
But here’s the thing: it’s tricky to say for sure that it’s just the processing of the food that’s the problem. Some experts think it could also be because these foods often have less fiber and more bad fats, sugar, and salt.
Good news, though! There are diets known to help keep your brain in tip-top shape.
The Mediterranean diet, which is all about plants and healthy fats, and the ketogenic diet, which is low in carbs and high in fats, both seem to do wonders for brain health. They can even help turn back the clock on some of the brain’s aging processes.
These diets might work by calming down inflammation in the body, which is your body’s way of fighting off things it doesn’t like.
Too much inflammation can be bad for your brain. Plus, what you eat can affect your gut in ways that end up affecting your brain, too.
But figuring out exactly how individual foods affect us is hard. People live complicated lives, and many things influence our health, not just our diets. That’s why scientists also study animals like rats, which can give us clues about how food affects our brains.
As we all get older and more people start facing problems like dementia, understanding the link between our diet and brain health is becoming more and more important.
So, the next time you’re about to grab a snack, remember: what you choose to eat might just be fuel for thought.
If you care about brain health, please read studies about how the Mediterranean diet could protect your brain health, and Omega-3 fats and carotenoid supplements could improve memory.
