Lutein is a naturally occurring pigment commonly found with zeaxanthin. Your eyes contain these nutrients, both of which might help filter harmful light rays that enter your eyes. As of 2011, researchers of the National Eye Institute continue to evaluate the potential of lutein in protecting your eyes and vision from damaging diseases. Knowing about the possible benefits of this nutrient will help you talk to your doctor about whether you should take lutein to protect your vision.
Macular Degeneration
Macular degeneration is a condition that damages an area of tissue on the back of your eye, and this tissue helps provide the straight-ahead vision you rely on for daily tasks, such as driving. Macular degeneration will typically result in vision changes or blindness. Treatments will not restore vision lost to this condition, but lutein might play an important role in protecting your macula from vision changes. In a study conducted at Harvard University by Dr. Johanna Seddon, research determined that lutein could, in fact, reduce the risk of macular damage, reports the American Macular Degeneration Foundation. The National Eye Institute continues to research the role of lutein in preventing this condition.
Cataracts
Lutein might also prove beneficial in preventing cataracts, which occur when the proteins and fats that form the lens inside your eye break down and form clumps of material in the lens. This condition will cause the lens to gradually turn cloudy and hard, resulting in blurred vision and difficulty reading. The cataract might also have a yellowish appearance, and this might cause colors to have a muted or dingy appearance. Cataract surgery will resolve the condition, but lutein could help slow down the formation of cataracts or help prevent cataracts from forming.
Sources
Many foods contain lutein, including dark green, leafy vegetables, such as spinach and kale. Other lutein-rich foods include collard greens, corn, green peas and broccoli. If you decide lutein might help your eyes, you should talk with your doctor before you increase your lutein intake. She can help you determine the appropriate amount of lutein you should have each day. Your doctor can also help you determine if you should take a lutein supplement or if you should use your diet to provide you with the necessary amount of this nutrient.
Consideration
Certain foods that contain lutein, such as dark green, leafy vegetables, might contain other nutrients that may interfere with the treatment of certain blood conditions or blood thinning medications. If you have a blood condition or take a medication such as Coumadin, you should work closely with your doctor to determine the appropriate amount of these foods you should eat each day.
