QUIZ: Are You Eating For Healthy Eyes?

Sunglasses and summertime go together like, well, sunglasses and summertime! Even if it’s only for fashion, you’re still protecting your eyes from harmful UV rays. But what about those times when you’re out of the sun and absorbing blue light from computer and smartphone screens? Blue light can harm eyes and negatively impact overall health, particularly sleep quality. Protecting your eyes from the inside is equally important and it starts with what you eat.

“The things that make us healthy from a physical standpoint and protect us from heart disease and diabetes turn out to be the exact same things that protect our eye health,” said Dr. Kim Reed, professor of optometry at the Nova Southeastern University College of Optometry and founder and director of the Ocular Nutrition Clinic at Nova Southeastern University’s Eye Care Institute, in a recent interview with BlackDoctor.org.

Although it’s statistically much more common for eye diseases to affect the elderly than young people, Dr. Reed stresses that failing eyesight isn’t something that should automatically be accepted as just another fact of getting older. “Let’s say your family has a strong history of diabetes, type 2 diabetes, does that mean you’re inevitably going to fall into that pattern? Absolutely not. Even though you may have a predisposition, that doesn’t mean that you can’t do things and take steps to protect yourself from those diseases.”

The foods we eat act as a type of “sunscreen” for our eyes, says Dr. Reed. “To date, the best information we have from the science is that there is this one particular substance that is the most protective in your eye and it is called lutein, and that is the nutrient that’s in green leafy such as spinach and kale and collards and turnips greens and swish chard and things that look and feel like that. If we have a lot of that in our diet it will deposit itself in many body tissues including the retina in our eye and it acts like a sunscreen.” Having enough lutein in the eyes can help protect you from damage or potential damage that’s occurring with blue light from electronic devices.

In addition to adding more dark, leafy greens to your daily diet and limiting processed foods, the single most important thing you can do for your eyes, according to Dr. Reed, is to not smoke. The second most important thing is to maintain body weight and not carry around excess fat tissue “because it’s toxic to many body systems, including eyes.”

So, how well are you protecting your eyes? Dr. Reed developed an eye quiz because many people are misinformed about their eye health. Eating a lot of carrots, or having a salad for lunch every once in awhile isn’t enough to protect your eyes.

Take the quiz on the next page to see if your lifestyle habits are on point for good eye health, and learn what you can do to get – or keep – your eyes healthy for years to come.

ANSWERS

Mostly 1s: AAAmazing!  Or A Plus for eye nutrition!

Keep it up! Being a healthy weight, eating a balanced diet rich in omega-3s and antioxidants, having healthy habits such as getting enough sleep and avoiding smoking and excessive alcohol, and limiting screen time all contribute to healthy eyes. There are things you can do to further support your eye health. Ask your eye doctor if you should consider supplementing your healthy diet with eye-supporting nutrients, such as lutein, zeaxanthin, vitamin E, and DHA/EPA omega-3s. Wearing protective sunglasses and getting regular eye exams can also increase the likelihood that your eyes will stay healthy well into the future. Finally, be sure to cook those dark leafy greens you’re eating in a small amount of fat – doing so will increase the absorption of their nutrients!

Mostly 2s:  B on the right track in no time!

You’re on the right track, but, like many of us, you can make some minor adjustments to support your eye health even more. If you’re not eating enough leafy greens, omega-3-rich foods like fatty fish, or vitamin -rich foods like nuts, berries, and citrus fruits, you can still get the right amount of these essential nutrients through supplementing. Consider one that contains 10 mg of lutein and 2 mg of zeaxanthin for your eyes. And don’t worry – you’re not alone in needing some help! Only 10% of adults in the U.S. are getting the recommended amount of lutein and zeaxanthin they need to reduce the risk of age-related eye diseases.

Mostly 3s:  C your way to better health!

Your lifestyle and eating habits may be putting your eye health at risk, say several research studies.  But it’s never too late to start to take back control of your health. Avoid highly processed foods and limit your intake of added sugars in pastries, treats, and cereals.  Instead, eat more foods that are high in nutrients, especially lutein and zeaxanthin, like leafy green vegetables, brightly colored vegetables, corn and eggs. However, getting enough of these nutrients daily through food alone can be difficult. Taking a daily supplement with 10 mg lutein and 2 mg zeaxanthin is a great way to ensure you get some of the vital nutrients your eyes need. Also, eat at least two servings of fatty fish, like salmon, sardines, or fatty tuna each week, or take a high quality omega 3 supplement. Other healthy habits – like quitting smoking, getting your weight into a healthy range, and getting enough sleep at night will support not only your eye health, but the health of your entire body. You can do it! And your eyes will thank you.
