6 Best Foods for Geographic Atrophy, According to Research

Leafy greens like spinach are packed with the healthy-eye nutrients lutein and zeaxanthin. These are carotenoids, a group of plant compounds that give fruits and vegetables their vibrant colors, and they are especially helpful for preventing and slowing the progression of GA.
“Lutein and zeaxanthin are concentrated in the macula, which is the very center part of your retina, and that is the most important area for vision. It’s also, unfortunately, the area where geographic atrophy tends to hit,” Dr. Patel says.
Thanks to their antioxidant properties, lutein and zeaxanthin help protect the macula from oxidative stress (an imbalance between antioxidants and cell-damaging molecules known as free radicals) and help absorb harmful blue and ultraviolet light.
The recommended daily intake of lutein is 10 milligrams (mg), while zeaxanthin is 2 mg. Two cups of spinach (roughly the amount found in a salad) provides 1,500 micrograms (mcg), which is 1.5 mg, of combined lutein and zeaxanthin — a step in the right direction in meeting the recommendation.
