Simple food hack slashes nearly 8 years off your brain age!

I know folks who'll do just about anything to get rid of wrinkles and age spots, and I get it. No one wants to be reminded of the march of time whenever they glance into a mirror.

But you know the old saying: it's what's inside that really counts.

That's especially true when it comes to aging, because your vital organs also suffer some wear-and-tear over the years. And while you can see the lines on your face, you can't see the damage on the inside.

You can't see it... but you CAN do something about it.

Age-fighting antioxidants can help keep you young on the inside. And now, new research reveals how those same healthy nutrients can practically stop time in your brain.

This study focused on a modified version of the Mediterranean diet that focuses on specific foods proven to help protect the brain.

It allows fish, poultry, berries, beans, nuts, whole grains, olive oil, leafy greens and even a glass of wine a day. It also limits red meat, pastries and other sweets as well as butter and cheese, and practically eliminates fried foods and fast foods.

It's a "sacrifice" worth making (I mean just LOOK at that list of delicious foods!), because the new study shows how following this diet closely can help keep you sharp as a tack well into your 80s.

Seniors who stuck closest to this diet did so much better on cognitive tests that by the end of the five-year study -- when they were 81 years old on average -- they had brains that were 7.5 years "younger" than those of the folks who didn't follow the plan very closely.

The study doesn't look at the reason, but it's not too hard to figure out.

This diet is not only low in brain-rotting sugars and other carbs as well as unhealthy fats, it's also rich in the nutrients your brain needs most -- including antioxidants from berries and greens as well as brain-boosting fats from olive oil and fish.

Those same nutrients are why a previous study found that following this diet closely can slash your risk of Alzheimer's disease by 54 percent -- and sticking to it even moderately can cut your risk by more than a third.
