By now, you know that 2020 On-site is all about eye health, especially eye care in the workplace. But we’re not always at work, and we’re all eating (at least) 3 meals a day. So in the spirit of general eye health information, and because we got a little bit hungry, we started thinking about how (and what) we can eat to keep our eyes healthy.
You’ve probably heard the saying, “you eat with your eyes first”--meaning that if something looks appetizing to you, you’re more likely to want to consume it. Of course, we use all of our senses, not just our eyes, when it comes to food--we consider how it smells, tastes, its “mouth feel” (a term used by food pros but we all understand what it means.) Even how it sounds as it’s cooking--think of the sizzle of a steak on the grill. Maybe your mouth is watering already.
We eat FOR our eyes, too--or, to be more specific, we should be eating for eye health. Parents all over the country talk up the value of carrots and the Vitamin A they contain--and they’re right--but that’s just the beginning. Certain nutrients boost eye health, and can prevent some eye diseases.
You already know that eating right is the way to keep your heart healthy. The good news is that the same diet that helps your heart is also good for your eyes. A diet low in fat and rich in fruits, vegetables and whole grains is what to aim for, for the heart and the eyes. Since your eyes rely on tiny arteries for oxygen and nutrients, just as the heart relies on much larger arteries, this makes sense. Keeping those arteries healthy will also help your eyes.
It’s not hard to get eye-friendly foods into your diet. The American Optometric Association recommends the following nutrients and antioxidants--as essential for improving eye health.
For lutein and zeaxanthin, think spinach, kale, collard greens, broccoli, and brightly-colored fruits like kiwis and grapes. Other dark leafy green vegetables, like spinach, romaine lettuce, peas, corn, collards and turnip greens, also contain significant amounts of lutein and zeaxanthin.
Sources of Vitamin C include all citrus fruits--oranges, grapefruit, tangerines, and lemon. Lots of other foods offer benefits similar to oranges, with kiwi fruit being a Vitamin C powerhouse. Peaches, papayas, red and green peppers, tomatoes and strawberries are also high in C.
Many of us don’t get enough Vitamin E in our diets. Boost that by eating a small handful of sunflower seeds, or use a tablespoon of wheat germ oil in your salad dressing. Almonds, pecans, and vegetable oils are also good sources of Vitamin E.
Legumes of all kinds, including black-eyed peas, kidney beans, lima beans, and peanuts contain zinc. Other foods high in zinc include oysters, lean red meat, poultry, and fortified cereals.
6. Vitamin A. Vitamin A plays an important role in vision, bone growth and health of the immune system. Vitamin A also helps the surface of the eye, mucous membranes, and skin be effective barriers to bacteria and viruses, reducing the risk of eye infections.
Vitamin A can be found in eggs, carrots, sweet potato, kale, spinach, apricots, broccoli, butter, beef liver, and winter squash.
“Eat the Rainbow,” say nutritionists, and they’re absolutely right when it comes to eye health. Aim for 3 servings a week of the Top 6. Here’s a handy shortcut list to get you started (or keep you going.) Note: some nutrients contain more than one of the top 6, so that’s a nice bonus!
Lutein & Zeaxanthin: Broccoli, Brussels sprouts, collard greens, corn, eggs, kale, nectarines, oranges, papayas, romaine lettuce, spinach, squash.
Omega-3 Fatty Acids: Flaxseed, flaxseed oil, halibut, salmon, sardines, tuna, walnuts.
Vitamin A: Apricots, cantaloupe, carrots, mangos, red peppers, ricotta cheese, spinach, sweet potatoes.
Vitamin C: Broccoli, Brussels sprouts, grapefruit, kiwi, oranges, red peppers, strawberries.
Vitamin E: Almonds, broccoli, peanut butter, spinach, sunflower seeds, wheat germ,
Zinc: Chickpeas, oysters, pork chops, red meat, yogurt.
WHAT ABOUT SUPPLEMENTS?
In general, a multivitamin may be a good idea, but always check with your doctor before taking any supplements. Some can be dangerous in high doses, and others may interfere with medications you may be taking for certain conditions.
FOOD IS NOT ENOUGH: SCHEDULE YOUR ANNUAL EYE EXAM
And of course, in addition to eating for your eyes, you can protect the health of your eyes by getting an eye exam every year. Combining good nutrition with yearly checkups will increase your defense against serious health conditions.
