Macular degeneration is an eye disease that results in permanent vision loss. Early symptoms may include blurry vision. You may find it more difficult to read, watch television or recognize the faces of friends and family. As the condition worsens, straight lines, such as telephone poles, may appear bent or broken, and many people have nearly complete loss of central vision. Certain nutrients found in foods such as eggs may help prevent or slow down this progressive condition.
Types
Macular degeneration occurs in two forms. The first type is called dry macular degeneration and stems from the breakdown of cells in the macula, a pigmented region in the center of the retina of the eye. In the second type, wet macular degeneration, abnormal blood vessels grow under the macula and leak blood. This lifts the macula out of position and results in sudden, significant vision loss.
Eating eggs alone does not prevent, treat or slow down macular degeneration. However, some of the nutrients in eggs may help provide necessary vitamins and minerals that promote macular health.
Omega-3
In an effort to produce healthier eggs, some growers feed their hens grains or seeds rich in omega-3 fatty acids, and the eggs from these hens typically contain omega-3. This essential fatty acid may help prevent or slow down the progression of damage from macular degeneration.
Lutein and Zeaxanthin
Lutein and zeaxanthin are naturally occurring pigments found together in many foods, such as eggs. Since a typical macula holds onto these pigments, consuming foods or supplements rich in lutein and zeaxanthin may help nourish and strengthen macular tissue, protecting your eyes from advanced macular degeneration damage.
Other Dietary Sources
Additional foods that contain omega-3 fatty acids include salmon, mackerel, walnuts and flaxseed. Many foods, particularly green, leafy vegetables like kale, collard greens and spinach, contain significant amounts of lutein and zeaxanthin. These foods may also help prevent macular degeneration.
Considerations
Consuming large quantities of eggs could lead to increased cholesterol and triglycerides levels or other health conditions. If you want to ensure getting an adequate intake of nutrients that help reduce the risk of damage from macular degeneration, you may need to take a vitamin designed for eye health. Talk with your health care provider to determine how often you should eat eggs, as well as to determine if a supplement may work with your overall health condition.
