DESCRIPTION: Yellow plant pigments such as lutein and zeaxanthin build up in the back of our eyes to protect our retinas against age-related macular degeneration. Levels of these eyesight--saving nutrients in organic free-range eggs, vegetables, and goji berries are compared.
I've previously touched on this important topic in Preventing Macular Degeneration with Diet (http://nutritionfacts.org/video/preventing-macular-degeneration-with-diet/). I've also covered other leading causes of blindness such as cataracts (Preventing Cataracts with Diet, http://nutritionfacts.org/video/preventing-cataracts-with-diet/) and glaucoma (see my last video, Greens vs. Glaucoma, http://nutritionfacts.org/video/greens-vs-glaucoma, and my next video, Dietary Treatment of Glaucoma, http://nutritionfacts.org/video/dietary-treatment-of-glaucoma).
In Egg Industry Blind Spot (http://nutritionfacts.org/video/egg-industry-blind-spot/) I compare the levels in eggs to greens.
Though they didn't appear to boost a measure of immune function (Boosting Natural Killer Cell Activity, http://nutritionfacts.org/video/boosting-natural-killer-cell-activity), goji berries one of the most antioxidant-packed snacks out there. A tip on getting them inexpensively can be found in my video Are Goji Berries Good for You? (http://nutritionfacts.org/video/are-goji-berries-good-for-you/).
Have a question for Dr. Greger about this video? Leave it in the comment section at http://nutritionfacts.org/video/dietary-prevention-of-age-related-macular-degeneration/ and he'll try to answer it!

Hi Dr. Greger. Just wanted to point out that UV light does not reach the retina. It is absorbed in the lens and cornea before it can reach the retina. Current generation cataract lenses come with a UV filter and are tinted yellow.
I would love to see more updates on this subject. As an optician I see many people with mild to severe MD. They often ask, what can I do to prevent worsening of the symptoms? I really feel sad for them because they don't have a clue. Typically they are overweight smoke and drink, where do I start explaining that it's too late to fix the problem and they need to turn their whole world around. Usually I tell them to live a healthy lifestyle and to keep in contact with their doctors.
Dr. Gregor, I was born with a small triangle-looking cataract on my right eye. This eye has gotten so much better in the 45 days of transitioning to a whole food, plant based diet and my question is: Can eliminating animal and animal based foods from my diet make it go away? Or am I just stuck with it? Thanks!
It will not go away with diet because the eyelens is not in contact with your bloodstream. If it gets worse you can have cataract surgery. Eating like the Doctor recommends helps in many ways but cataract is not a reversible condition. I am not a doctor but an optician, if in any doubt talk to your optician or doctor.
I was in the health food store a few days ago, and I saw where one can purchase zeaxantin and lutein supplements. Since this is a very critical issue, it seems like taking these supplements would be a prudent thing to do along with eating goji berries, spinach, and other veggies. It seems that the supplements would just be added insurance. What say you?
...Viewers ...this is well done...Attention Viewers, I treat this macular degeneration problem everyday, 1,000's per year and this video summarizes the facts...and the preventive treatment options...If you eat right starting now, then you avoid my $1,000 per shot monthly wet macula treatments when your #macula has premature aging and starts leaking...
wow, thought you were going to pitch something but that came from the heart. thank you for your expertise... I have not been diagnosed yet, but when I do the grid test, my right eye if I stare long enough the lines do become a little squiggly, not much though. But nonethe.less I have been donig it all day to see and yes after staring at the dot for about 10 sec it starts to get squiggly. boxes stay same though. When I do the test on the black background and white boxes, the lines don't really move only when I do the white background black boxex. Would you say I am early stage md? I'm only 49, but am determined to live my life to the fullest. I believe in the poiwer of thought and also healing by eating the right foods. Have you seen people arrest the development of the MD with diet?
I've just noticed that my vision is starting to waver(turning 40 soon)...will the foods with zeaxanthin help? Can I get back my 20/20 vision with food, or is just inevidable that I'll eventually need glasses?
Imagine a life without vision… and then feast your eyes on this week’s eye-sight saving video about preventing macular degeneration: http://nutritionfacts.org/video/dietary-prevention-of-age-related-macular-degeneration/
TRANSLATED THIS VIDEO TO PORTUGUESE IN AMARA(DOT)ORG. CAN YOU UPLOAD THEM IN THIS YOUTUBE LOCATION? We could put these videos in many more languages and make them reach far in the world, info references on how to keep ourselves healthy. Many volunteers will surelly translate. I have done it ; )
Wonderfully simple how the same diet that prevents most cancers, heart disease, etc, also prevents eye diseases. So beautifully simple, yet nearly everywhere I look, the vast majority of people appear to be committing a slow, expensive, painful form of food based suicide. Perhaps this won't change dramatically until financial incentives change ... imagine meat, dairy and egg subsidies gone, AND health insurance premiums to reflect dietary decisions? Is this possible, or must it happen? Our "magical" president, in his younger years, learned from Dr. John McDougall in Hawaii, the real cause of most chronic diseases ... animal based DIETs. He promised us hope, and getting tough on GMO's ... and magically delivered us the Monsanto Protection act ... and a lame website that "lets" healthy consumers subsidize health care insurance for the people lured into eating the junk that govt. promotes and subsidizes ... meat, dairy, eggs. Epidemic obesity, diabetes, etc ... sponsored by big pharma, big ag, FDA, USDA, etc.
Agreed, everyone is up in arms about health care these days, because let's face it, if you eat the Standard American Diet, you ARE going to get sick.
So sad people DON'T realize the FDA, USDA, in bed with big pharma, can't WAIT for you to get sick, so they PROFIT.
Just to add some info- Substantial amounts of lutein and zeaxanthin (30-50%) were also present in kiwi fruit, grapes, spinach, orange juice, zucchini (or vegetable marrow), and different kinds of squash.
Most of the dark green leafy vegetables, previously recommended for a higher intake of lutein and zeaxanthin, have 15-47% of lutein, but a very low content (0-3%) of zeaxanthin. Our study shows that fruits and vegetables of various colours can be consumed to increase dietary intake of lutein and zeaxanthin.
Recently the New York Times had a column in which the author, who worked with Dean Ornish, took a rather mean and nasty shot at Ornish and presented her recipes for eggs- of course, this being the NYT, organic, pastured, grass fed , etc. If one brought up the fact that eggs have like 70% of the daily allowance for dietary cholesterol, there was some foolish, and I mean DEEPLY FOOLISH, babble about how dietary cholesterol was not to blame for heart attacks and cardio vascular disease. OY!
Spinach should do it too (according to the quoted study).
A 100g cooked shredded serving provides 20-40 mg of zeaxantin.
Raw is probably a bit higher.
Kale, turnip greens, collard greens also have a good amount per serving.
Goji berries in fact are an unreliable source, concentrations from 2 to 200mg/100g have been reported.
Many other healthy green foods also contain non-neglible amounts, e.g. broccoli, corn, peas...
Heck, even iceburg lettuce has some few mg/100g - in fact better than egg yolk from free range eggs.
No idea about supplementation - perhaps, but have to check dosage. You would need >6 mg daily.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
