A new study conducted by Eric Ammann of the University of Iowa and published in Neurology®, the journal of the American Academy of Neurology, on Sept. 25, 2013, is the first to indicate that consumption of omega-3 fatty acids may not benefit thinking skills as previously reported in other research.
Omega-3 fatty acids are contained in nuts, fish, strawberries, kiwi, and supplements. The term omega-3 fatty acids covers eleven different compounds that have been studied together and separately to determine the beneficial effects of the compounds in humans.
The study involved 2,157 women between the ages of 65 and 80. The women received blood tests for omega-3 fatty acids and tests of thinking and memory skills annually for six years.
The results showed no difference in memory of thinking skills in the women who consumed a high level of foods or supplements containing omega-3 fatty acids and those who did not. There was no difference in the rates of dementia in the women who consumed omega-3 fatty acids and those who did not.
The researchers do not conclude that any person should stop or start consuming omega-3 fatty acids based on this one research study.
One might consider litigation against any omega-3 fatty acid manufacturer that ever claimed omega-3 fatty acids improved thinking or prevented dementia.
