There is an obvious reason to take good care of your eyes. To protect your vision.
But there is another reason that is equally important. It’s something people don’t hear much about. So it always comes as a surprise to my patients when I tell them this:
“If you want to protect your brain, it’s urgent that you take immediate measures to support healthy vision.”
It sounds crazy, right? But it’s not.
As hard as it might be to imagine this, your retinas are actually an extension of your brain and central nervous system. This means any neurodegeneration in the eyes can spread to the brain. (And as you may well know, Alzheimer’s disease is a neurodegenerative disorder of the brain.)
And here’s a pretty frightening little factoid:
The eyes and brain are so closely linked that many of today’s most common vision problems increase your risk of Alzheimer’s by up to 50%! Vision-robbing conditions like macular degeneration, glaucoma and diabetic retinopathy are particularly devastating to your mental function.
I’ve seen it many times over the years in my own patients. Those with eye disorders and low macular density often start showing signs of mental decline and the onset of dementia.
Interestingly, I’ve also noticed something else about these patients. They frequently have low levels of two specific carotenoids; lutein and zeaxanthin.
So is it possible that these two well-recognized “eye nutrients” might have something to do with the brain?
Sure it is!
Save Your Vision to Save Your Brain
The amount of lutein and zeaxanthin in your macula has a direct correlation to the amount in your brain. In other words, if your macula is brimming with these nutrients, so is your brain.
But if your macula is deficient in them, your brain is, too. And a situation like this could place you at extremely high risk of Alzheimer’s.
You see, lutein is the primary carotenoid found in the brain. It accumulates in the membranes where it works together with zeaxanthin to promote cognitive function and enhance neural efficiency as you age. (This is true even if you don’t start consuming more of them later in life.)
These two carotenoids also enhance white matter integrity in regions of the brain that are vulnerable to age-related mental decline.
And here’s the best part.
People who increase their intake of these two nutrients can actually boost their cognitive abilities. They show improved attention and processing speeds. They are able to “switch gears” more quickly. They also tend to show better working memory and mental flexibility.
Interestingly, neither of these nutrients is hard to find. You can get plenty of them in your every-day meals.
All you have to do is add plenty of dark leafy greens to your dinner plate. This includes vegetables like kale, turnip greens, collards, spinach and chard. All of them pack a hefty dose of both lutein and zeaxanthin and are easy to add to your diet.
I suggest finding as many ways as you can too add more dark, leafy green vegetables to your meals. Put them in your omelets, salads, smoothies, soups, veggie wraps and wherever else you can think of. Serve them as side dishes with dinner, or sauté them up in a stir fry as your main entrée.
To get maximum support for both your eyes and your brain, I also recommend supplementation. A good eye formula that contains at least 12 mg of lutein and 2 mg of zeaxanthin – along with other eye and brain-supporting nutrients like omega-3 fatty acids, zinc, and vitamins A, C and E – is always a good idea.
