It is true, adding certain nutrients to your diet every day, either through foods or supplements, can help save your vision. Researchers have linked nutrients such as lutein/zeaxanthin, vitamin C, vitamin E, and zinc to reducing the risk of certain eye diseases, including macular degeneration and cataract formation.

Here are some facts about these vision-saving nutrients:

  • Lutein and zeaxanthin reduce the risk of age-related vision problems, including age-related macular degeneration and cataracts. These important nutrients are found in green leafy vegetables, such as kale, spinach and turnip greens, as well as other foods, such as eggs.
  • Vitamin C (ascorbic acid) is an antioxidant found in fruits and vegetables. You can find it in fruits like oranges, kiwi, and strawberries, as well as vegetables like broccoli, mustard greens, and peppers. Scientific evidence suggests vitamin C lowers the risk of developing cataracts, and when taken in combination with other essential nutrients, can slow the progression of age-related macular degeneration and visual acuity loss.
  • Vitamin E in its most biologically active form is a powerful antioxidant. It can be found in nuts, like almonds, peanuts and pine nuts, dried apricots, sunflower seeds, fortified cereals and sweet potatoes. It is thought to protect cells of the eyes from damage caused by unstable molecules called free radicals, which break down healthy tissue.
  • Essential fatty acids are a necessary part of the human diet. They maintain the integrity of the nervous system, fuel cells and boost the immune system. Two omega-3 fatty acids have been shown to be important for proper visual development and retinal function.
  • Zinc is an essential trace mineral or ‘helper molecule’. It plays a vital role in bringing vitamin A from the liver to the retina in order to produce melanin, a protective pigment in the eyes. Zinc is highly concentrated in the eye, mostly in the retina and choroid, the vascular tissue layer lying under the retina.

Now we know that incorporating vitamins in our diet can provide protection from eye diseases that arrive later in life. No matter your age, be proactive in your health. Strive to include as many colors of fruits and vegetables as possible!
