8 Nutrients That Will Optimize Your Eye Health:  Of the five senses, your eyesight is arguably the most significant.

Although overall health and eye health are closely related, certain nutrients are particularly crucial for your eyes.

These nutrients lessen the onset of age-related degenerative disorders, shield your eyes from damaging light, and support eye function.

1. Vitamin A

 

  • One of the leading causes of blindness worldwide is a vitamin A deficiency.

 

  • Maintaining the light-sensing cells in your eyes, called photoreceptors, is dependent on this vitamin.

 

  • Depending on how severe your vitamin A shortage is, you could suffer from night blindness, dry eyes, or even more dangerous diseases.

 

  • Only foods originating from animals contain vitamin A. Dairy products, egg yolks, and liver are the richest dietary sources.

 

  • Provitamin A carotenoids, which are antioxidant plant chemicals present in high concentrations in many fruits and vegetables, are another source of vitamin A.

 

  • On average, provitamin A carotenoids supply 30% of the vitamin A needed by humans. Among them, beta-carotene is the most effective.

2–3. Lutein and Zeaxanthin

 

  • Macular pigments, or yellow carotenoid antioxidants, include lutein and zeaxanthin.

 

  • The macula, a layer of light-sensitive cells on the rear wall of your eyeball, is the center of your retina and is where they are concentrated.

 

  • Zeaxanthin and lutein act as a natural sunscreens. They are believed to be essential in shielding your eyes from damaging blue light.

 

  • Research under control indicates that the amount of lutein and zeaxanthin you consume is directly related to how much of each mineral is in your retina.

 

  • A considerable reduction in the incidence of AMD was shown in one observational trial involving middle-aged and older persons who consumed 6 mg of lutein and/or zeaxanthin daily.

 

  • Additionally, the researchers found that, in comparison to individuals with the lowest intake, those with the highest intake of lutein and zeaxanthin had a 43% decreased risk of macular degeneration.

 

  • The evidence isn’t totally consistent, though. According to a meta-analysis of six observational studies, lutein and zeaxanthin do not prevent AMD in its early stages; rather, they only offer protection against the disease in its later stages.

 

  • Zeaxanthin and lutein are typically found in meals together. The best sources include kale, spinach, Swiss chard, parsley, pistachios, and green peas.

 

  • Moreover, lutein and zeaxanthin levels may be elevated in egg yolks, sweet maize, and red grapes .

4. Omega-3 Fatty Acids

 

  • Additionally, the researchers found that there was a 43% reduction in the risk of macular degeneration among those with the highest intake of lutein and zeaxanthin as opposed to those with the lowest intake.

 

  • The evidence isn’t totally consistent, though. Lutein and zeaxanthin appear to offer protection against AMD only in its advanced phases, not in its early stages of development, according to a meta-analysis of six observational studies.

 

  • Zeaxanthin and lutein are typically found in meals together. The best sources are kale, spinach, Swiss chard, parsley, pistachios, and green peas.

 

  • Additionally, red grapes, sweet corn, and egg yolks may all have significant lutein and zeaxanthin content.

 

5. Gamma-Linolenic Acid

 

  • Small levels of the omega-6 fatty acid gamma-linolenic acid (GLA) can be found in the typical modern diet.

 

  • GLA seems to have anti-inflammatory qualities, in contrast to several other omega-6 fatty acids.

 

  • Starflower and evening primrose oils are the highest sources of GLA.

 

  • Taking evening primrose oil may help to lessen the symptoms of dry eye illness, according to some data.

 

  • In a randomized controlled trial, evening primrose oil containing 300 mg of GLA was administered once a day to women suffering from dry eyes. Over a six-month period, the study found that their symptoms improved.

 

 

6. Vitamin C

  • Small levels of the omega-6 fatty acid gamma-linolenic acid (GLA) can be found in the typical modern diet.

 

  • GLA seems to have anti-inflammatory qualities, in contrast to several other omega-6 fatty acids

 

  • Starflower and evening primrose oils are the highest sources of GLA.

 

  • Taking evening primrose oil may help to lessen the symptoms of dry eye illness, according to some data.

 

  • In a randomized controlled trial, evening primrose oil containing 300 mg of GLA was administered once a day to women

 

  • suffering from dry eyes. Over a six-month period, the study found that their symptoms improved.

 

 

7. Vitamin E

 

 

  • A class of fat-soluble antioxidants known as vitamin E shields fatty acids from damaging oxidation.

 

  • Since fatty acids make up a large portion of your retina, getting enough vitamin E is essential for maintaining good eye health.

 

  • While blindness and retinal degeneration can result from a severe vitamin E deficit, it’s uncertain if taking supplements can help if you currently get enough from your diet.

 

  • Consuming more than 7 mg of vitamin E per day may lower your risk of age-related cataracts by 6%, according to one analysis.

 

  • On the other hand, vitamin E supplementation do not appear to impede or stop the advancement of cataracts, according to randomized controlled trials (34).

 

  • Nuts, including flaxseed oil, sunflower seeds, and almonds, are among the finest dietary sources of vitamin E (35).

 

8. Zinc

  • Zinc content is high in your eyes.

 

  • Superoxide dismutase is one of the many vital enzymes that contains zinc and serves as an antioxidant.

 

  • Additionally, it seems to play a role in the development of retinal pigments responsible for vision. For this reason, night blindness may result from zinc deficiency.

 

  • Zinc supplements were administered to elderly patients with early macular degeneration in one study. Compared to those who got a placebo, their macular degeneration was reduced, and their visual acuity was maintained more effectively.

 

  • But before any conclusions can be drawn, more research is required.

The Bottom Line

 

  • Healthy lifestyle habits, such as a wholesome diet and regular exercise, may help prevent many chronic diseases, including eye conditions.

 

  • Getting enough of the nutrients listed above may help reduce your risk. Other vitamins may also play a role in eye health.

 

  • However, don’t neglect the rest of your body. A diet that keeps your whole body healthy will likely keep your eyes healthy, too.
