It’s no secret that implementing a healthy diet into your daily routine comes with numerous benefits. Improving your immune system, strengthening your bones, and lowering your risk of heart disease are just a few outcomes that follow a healthy diet.
Another notable benefit is how eating healthy affects your eye health. As the most valued of the five senses, your sight is important to consider when thinking about your overall health and wellness.
Throughout this guide, you’ll learn more about the connection between nutrition and eye health and what you can do to help protect your vision.
How Nutrition Plays a Role In Maintaining Good Eye Health
Understanding how nutrition is relevant to your eye health can help motivate a more healthy lifestyle. What you consume matters to your vision because of the nutritional value of that meal.
Foods that are rich in vitamins and minerals (like vitamin A and lutein) are necessary for your eye health. Don’t be afraid to ask a trusted eye doctor about the types of foods they recommend for optimal eye health. Doing so can be the next step towards better sight.
Diet-related Eye Health Conditions
Before we dive further into which nutrients are best for eye health, you must first understand the eye health conditions that are linked to poor nutrition. Read below to learn about specific diet-related health concerns that can impact your eyesight.
Age-related Macular Degeneration (AMD)
Johns Hopkins Medicine defines age-related macular degeneration (AMD) as “a disease that affects a person’s central vision” and it’s “the most common cause of severe loss of eyesight among people 50 and older.” To elaborate further, AMD is a medical condition in which the macula (part of the retina) is damaged, affecting central vision.
One report on diet, age, and macular degeneration by the Brigham and Women’s Hospital states how the connection between vision loss and a poor diet can be a result of not consuming enough antioxidant properties like vitamins C and E.
Adding more foods, like fruits and vegetables, to your diet is a great way to combat this concern. Be sure to talk to an eye doctor when able if AMD is a concern for you or a loved one.
Cataracts
The Mayo Clinic describes cataracts as “a clouding of the normally clear lens of the eye.” Cataracts typically affect both eyes, but can do so at different rates. For instance, one eye may become more clouded at a rapid rate in comparison to the other. Additionally, there are different types of cataracts, adding more nuances to how the symptoms are perceived.
You can reduce your cataract symptoms by adding antioxidant-rich foods to your diet. This includes, but certainly isn’t limited to
- Broccoli;
- Grapefruits;
- Red and green peppers;
- Strawberries;
- Tomatoes;
- Oranges.
The more full of fruits and vegetables your plate is, the better your odds of reducing cataracts and other eye diseases.
Glaucoma
The American Academy of Opthalmology describes glaucoma as an eye disease that damages your optic nerve as a result of too much fluid built up in the front of your eye. There are a number of risk factors that can increase your odds of getting glaucoma including family history and age. Poor diet can be another contributor to glaucoma, too.
You can do your part in protecting your eyes from glaucoma by implementing a well-rounded diet rich in omega fatty acids. Note how you’ll want to avoid consuming alcohol and caffeine, for both can be contributors to glaucoma. Talk to an ophthalmologist and/or optometrist for further advice on how to prevent and correct your glaucoma symptoms.
Dry Eye Syndrome
Just as it sounds, dry eye syndrome is an optical health concern that prevents folks from producing tears. There are a few causes of dry eye syndrome including underlying illness (like grave’s disease or diabetes), environmental factors, and medication side effects.
Diet is another leading contributor to persistent dry eyes, as well. Overconsumption of foods high in artificial sugars and sodium, like fried food or candy, may lead to symptoms associated with dry eye syndrome.
You can avoid these symptoms by avoiding these foods and investing in those rich in vitamins, lutein, and zinc like peas or spinach. Talk to your optometrist about your symptoms to learn about other dry eye treatments.
Retinal Diseases
There are a number of retinal diseases including, but not limited to
- Diabetic retinopathy: Tiny blood vessels in the back of the eye that deteriorate and leak fluid into the retina as a result of diabetes;
- Retinal detachment: The presence of fluid is found under the retina, causing it to lift and separate from the underlying layers;
- Retinal tear: Shrinkage of the vitreous (a clear, gel-like substance across the eye) that shrinks enough to the point it tears.
Similar to the health concerns above, diet can either help or hinder your retinal disease symptoms. Be sure to incorporate foods rich in vitamins, minerals, and antioxidants in your diet to help prevent future or worsening signs of retinal disease.
Obesity
The Centers for Disease Control (CDC) defines obesity as “a complex disease that occurs when an individual’s weight is higher than what is considered healthy for [their] weight.” Obesity can be caused by lack of physical activity, insufficient sleep, genetics, or poor nutrition.
It’s a disease whose worldwide rate has doubled since 1980, affecting more than 1 billion people. This number could be reduced if folks had access to resources educating them on how to manage their weight in a healthy way.
Failing to take your health seriously not only leads to health concerns like obesity, but could lead to eye issues, as well. Obesity can increase your risk of getting cataracts, or even lead to blocked blood vessels in your eyes. We encourage you to see an eye doctor, alongside a weight management specialist, when curating a path to take to better your health and wellness.
Essential Nutrients for Eye Health
As briefly mentioned above, certain nutrients like vitamin A, omega fatty acids, and lutein are essential for healthy eyes.
- Beta-carotene: Beta-carotene is a provitamin that gives vegetables their coloring. You can only get beta-carotene through fruits and vegetables.
- Lutein and zeaxanthin: Lutein and zeaxanthin are examples of antioxidants needed to protect your eyes from ultraviolet rays. These antioxidants can be found in kale, spinach, and broccoli.
- Omega-3 fatty acids: Omega-3 fatty acids are great for protecting you from the eye diseases mentioned earlier in the article. It’s suggested you take 3 mg of omega-3 fatty acids per day. You can get this nutrient in some fish like salmon or sardines.
- Vitamins A and C: Vitamins A and C are necessary for the development of the ocular surface and photoreceptor rhodopsin. It’s recommended to take 400-700 mcg of vitamin A a day. Foods rich in vitamin A include fish, spinach, tomatoes, and eggs. It’s recommended you intake 500 mg of vitamin C per day, which can be done by eating bell peppers, strawberries, or brussels sprouts.
When in doubt, veggie out — eating vegetables is a great way to ensure you intake all of the vitamins mentioned above.
Recommended Foods for Eye Health
To reiterate, foods rich in the vitamins and minerals listed above are ideal when focusing on eye health. This means ensuring your diet is full of a variety of foods that not only are good for your eyes, but something you’ll enjoy eating, too.
Here are a few foods to consider for your eye health and tips for cooking with each.
- Incorporate dark, leafy greens like kale and spinach into your diet to increase your vitamin A and C intake. Doing so can dramatically lower your risk of AMD and cataracts. You can incorporate them into your diet by adding them to your smoothie or salad.
- Colorful fruits and vegetables like raspberries and avocados are excellent sources of lutein and other antioxidants. You can add fruits to your smoothie with leafy greens or use them in a citrus salad.
- Fish and other seafood can be consumed to increase your omega-3 intake. Sear them up on the grill or guy sushi grade fish and eat it raw.
- Nuts and seeds are rich in vitamins and proteins and can be used throughout your meals in a number of ways. For instance, you can turn them into spreadable butter or add them to your meals for an extra crunch.
What matters most is that you make the effort to utilize these foods more often with the intent of improving your eye health. As long as you’re consuming them, how you do so doesn’t matter nearly as much.
Tips for a Balanced Diet and Eye Health
Integrating new foods into your diet can take time to get used to. Reminding yourself on a daily basis of why you’re making these changes — to improve your overall health and wellness, including eye health — is a great form of self-motivation.
Additionally, you can stick to your goal of implementing eye-friendly nutrition into your life by:
- Taking the time to create a well-rounded meal plan tailored to your eye health goals;
- Combining ingredients from different food groups for maximum nutritional benefits;
