I'm in a macular degeneration group on FB. One person said they cured early mackie D by eating spinach daily for a month.
Here are other Australian Native Foods for eye health. I believe NZ has Warrigal Spinach. **Warrigal Spinach is very high in Lutein / zeaxanthin. Many articles if you google search.
SPINACH FOR MACULAR DEGENERATION - We just had a dinner party last night and an elderly gentleman from S. Africa told of us his brother-in-law who had severe macular degeneration. A nurse at the hospital passed along information for him to ask his doctor. After speaking with the doctor he decided to forego his quarterly eye injection. Instead, he began eating 2-3 tablespoons of slightly steamed/cooked spinach 3 times a day. His brother-in-law is now able to see, driving and woodworking. He said had he not seen it for himself, he wouldn't have believed it. I haven't any proof, but a few bites of spinach daily shouldn't hurt anyone. I hope it works!
