So how could another newly published study produce exactly opposite results? In fact, fish oil didn't just slow down the insidious progression of this eye disease, it restored vision to every patient placed on high-dose fish oil. It was therapeutic and curative, not just preventive.
The study I'm referring to is likely to be dismissed. The study group was small - only 25 patients. There was no inactive placebo pill given to another group of patients for comparison, a requirement for scientific validity. And it's also possible (but not plausible) that all the patients in the study were abjectly deficient in omega-3 fish oils, producing an atypical effect. But the study group was based in the Mediterranean where fish consumption is high. And it's not likely any placebo effect was involved.
The study is so convincing, especially when combined with all of the positive fish oil studies conducted over the last decade (see chart below), eye physicians would now be derelict in their duty not to recommend every long-living senior adult to consume more fish, or better yet - take concentrated fish oil capsules, if they want to maintain their sight throughout their retirement years.
