A recent article in a medical newsletter caught our attention with a headline -“Red Grapes found to offer significant protection against AMD and Blindness”. We analyzed the claims and the research behind them. Here are our findings:
1) The study compared the impact of a diet rich in antioxidants in mice prone to developing retinal damage in old age – similar to many humans. This particular study provided the antioxidants by means of red grapes – a well known source. The mice fed the grape enriched diet had significantly more protection against oxidative damage of the retina, preventing blindness.
2) Dr Finnemann from Fordham University in New York commented “The protective effect of the grapes in this study was remarkable, offering a benefit for vision at old age even if the grapes were consumed only at a young age.”
3) Another conclusion of the study “A diet rich in antioxidants, especially those provided by lifelong consumption of red grapes are directly beneficial to retinal health and function”.
Did you spot the weaknesses in the claims?
a) The study was carried out on mice. There is a good chance that similar results will be obtained with humans – but that is not guaranteed. In practice trials and results with humans are many years away
b) The best results came from a lifelong consumption of red grapes. Good results were also obtained if the grapes were fed only whilst the mice were young.
Things are looking good for all the mice that have been eating red grapes since they were babies. As for humans – how many of you have eaten several ounces/grams of red grapes every day since you were born? Neither have we.
Some Good News
Our own research confirms that regular intake of antioxidants can be a great help in protecting against AMD and other retinal problems. In fact, we know of many cases where eye damage from AMD has been successfully reversed using a special combination of antioxidants. And you don’t have to have been taking them throughout your life to benefit – but the earlier you start then the better is your protection.
Eat plenty of red grapes by all means – they are very good for you and taste delicious. But you also need regular top ups of powerful antioxidants. Many research studies have found that Lutein and Zeaxanthin are essential when addressing eye problems. The simplest and most effective method is by using a new product called NEW FOCUS. This is a simple “under the tongue” spray. The manufacturers of NEW FOCUS sublingual spray claim that the Zeaxanthin and Lutein will be delivered to the eye within 2 minutes of applying the spray. This is simple to use and helps protect against Diabetic Retinopathy, AMD, Glaucoma and many other eye disorders.
