If You Have Glaucoma, Eat More of These

In my last video, I discussed how eating goji berries with nuts and seeds can help build up yellow plant pigments such as lutein and zeaxanthin in our eyes to help fight age-related macular degeneration.

But once we’ve preserved the pigment in our retinal pigment epithelial cells, we need to keep them alive. This may be where anthocyanin phytonutrients come in. Anthocyanins (from the Greek anthos, meaning flower, and kyanos, meaning blue) are natural plant pigments that make pansies look purple and turn green cabbage into purple cabbage, yellow corn into purple corn, brown rice to purple rice, white potatoes to blue potatoes, orange carrots to purple carrots, and keeps blueberries blue and blackberries black.

As we age, our critical retinal pigment epithelium (RPE) layer starts to break down. However, we may be able to decelerate that aging with blueberries. In the study I profile above, human RPE cells bathed in blueberry anthocyanins had fewer free radicals and a lower proportion of aged cells, suggesting that blueberries and other red, blue, and purple pigmented fruits and vegetables may help prevent age-related macular degeneration. (Blueberries may be especially important for blue eyes, as can be seen in my video Greens vs. Glaucoma.)

Preventing disease is nice, but what if we already have a disease like glaucoma, an incurable eye disease in which our optic nerve, which connects our eyes to our brain, starts deteriorating, and we start losing our visual fields?

A few years ago, Japanese researchers showed they could apparently halt the progression of glaucoma with black currants. They gave people black currants for six months and found that black currants significantly boosted the blood flow to their optic nerve. The results suggest that black currants might be a safe and valuable option, but because the study was not double-blind and there was no control group, I didn’t report it when it was initially published. But now we have got just such a study. Glaucoma patients were split into two groups—half got black currants the other half didn’t.

If you click on the above video, you can see a measure of the deterioration of the patients’ visual fields in both groups in the two years leading up to the study. Despite taking the best glaucoma drugs on the market, the subjects’ visual fields deteriorated. Then the study starts. The berry-free control group continued to worsen, but the berries appeared to stop the disease in its tracks after both one and two years. And since there’s no downside to berries (only good side-effects!) in my professional opinion everyone with glaucoma should be eating berries every day.

For more on the latest science on preventing and treating vision loss, check out Greens vs. Glaucoma, where I detailed the best foods to help prevent glaucoma. My previous treatment of glaucoma can be found here: Prevent Glaucoma and See 27 Miles Farther.

.,If not God, i would have be totally blind. Brethren I am Grace by name i want to let all here know how i suffered from glaucoma for a very long time. in my fifteenth year i had eye issues, and i was taking to a doctor by my parents, the doctor diagnosed cataract in my eyes was the cause of my eye problem, so i was treated and i was no longer using glasses. But as i grew older i found out that i was losing the use of my eyes as i was having real shortsightedness so before i got married, it became very bad that i have to see a doctor again, and this time i was diagnosed of glaucoma, and the doctor said there is no cure to it. so i was suffering from glaucoma and i needed the cure desperately i lost Hugh amount of money to doctors in USA who claim they can assist reduce its effect but still nothing was done no improvement rather it was becoming worst. i always go to church and cry to God to please help me out of this situation. After some time i was seeing only the chest of someone standing in front of me i was not seeing the other part of the persons' body. So this prompted me to look for cure with all means. i surf the web and got several ways to cure it but i tried so many ways, and none worked out well. I came across someone who gave a testimony about how his cousin was cured of CJD through the use of herbal medicine administered to him by one Doctor Uwadia Amenifo he also includes the herbalist contact details, so i decided to try to ask him if he can cure me. i contact
