Macular degeneration is a prevalent eye disease that affects millions of people throughout the world. It is the most common cause of blindness in persons over the age of 50. Macular degeneration symptoms can range from minor blurriness to full vision loss in the central area of the visual field. Macular degeneration cannot be cured, however, treatments and a change in lifestyle can reduce the disease's progression. Two of these medications that have the potential in supporting this are lutein and zeaxanthin.
Understanding Lutein and Zeaxanthin
Carotenoids are plant pigments that include lutein and zeaxanthin. They are typically found in green leafy vegetables such as collard greens, spinach, and kale. Lutein and zeaxanthin additionally appear in orange and yellow fruits and vegetables such as maize and oranges. Because the human body cannot produce lutein and zeaxanthin, these nutrients must be acquired through diet or a dietary supplement.
Lutein and zeaxanthin are antioxidants that help protect the eyes from free radical damage, which is produced by unstable chemicals that can cause cell damage. These antioxidants are especially advantageous to the macula, a tiny portion of the retina that is responsible for clear central vision. Lutein and zeaxanthin assist to filter out damaging blue light and minimize the risk of oxidative stress, which can damage the macula.
Dietary Sources of Lutein and Zeaxanthin
The best approach to get lutein and zeaxanthin is to eat a diet high in fruits and vegetables. Lutein and zeaxanthin-rich foods include spinach, kale, collard greens, broccoli, peas, corn, and oranges. Certain varieties of eggs and morning cereals are additionally enhanced with lutein and zeaxanthin.
For greatest benefit, persons with macular degeneration should consume the best dietary sources of lutein and zeaxanthin. According to one study published in the journal Ophthalmology, consuming more lutein and zeaxanthin from dietary sources lowered the incidence of AMD by 43%.
Supplements for Lutein and Zeaxanthin
While lutein and zeaxanthin are primarily obtained from food, supplements can potentially be beneficial for those with macular degeneration. Supplements containing lutein and zeaxanthin are available in a variety of formats, including capsules, pills, and softgels.
The suggested lutein and zeaxanthin dosage varies depending on the product and individual needs. Most pills, on the other hand, contain between 6 and 20 mg of lutein and zeaxanthin per day. Before beginning any new supplement regimen, consult with a healthcare provider because excessive dosages of lutein and zeaxanthin may interfere with some drugs and produce negative effects.
Other Nutrients and Strategies for Managing Macular Degeneration
While lutein and zeaxanthin have significance for eye health, other nutrients may assist with macular degeneration management.
Fatty Acids Omega-3: Omega-3 fatty acids have long been known to be advantageous to overall health, yet they are particularly essential for eye health. They have anti-inflammatory effects that may aid in avoiding the development of AMD. Fish high in omega-3 fatty acids include salmon, tuna, and sardines. If you don't eat fish, you can acquire these fatty acids via supplements such as fish oil.
Zinc: Zinc is a mineral that is essential for immune system function and has antioxidant effects. It is abundant in the retina and serves a crucial role in sustaining good vision. Zinc has been proven in studies to lower sensitivity and the risk of AMD progression. Good dietary sources of zinc include oysters, beef, and chicken.
Vitamins C and E: Vitamin C and E are potent antioxidants that can help guard the eyes against cellular deterioration. Additionally, they contain anti-inflammatory qualities that could help with AMD prevention. Vitamin C-rich foods include citrus fruits, strawberries, and broccoli, whereas vitamin E-rich foods include nuts, seeds, and vegetable oils.
Use of tobacco has been associated with a higher incidence of AMD and other eye conditions. Your risk can be reduced and your general health can be improved by giving up smoking.
Don't forget to put your shades on. Sunglasses with UV protection can help shield the eyes from harmful UV rays. For people with AMD, whose eyes could be more sensitive to light, this is especially important.
