Consuming foods rich in omega-3 fatty acids cannot prevent or delay cognitive decline, a recent study suggested. The researchers have suggested that the fatty acid may not improve thinking skills in humans. However, the study results should not be used to change the diet patterns, the researchers recommended.
The study was published in the journal Neurology.
According to Dr. Eric Ammann, University of Iowa, USA, research on cognitive benefits of omega-3 fatty acids is one of the prime interests of medical community. However, the studies could not find any beneficial effects in geriatric women. Such results were confirmed by several randomized clinical trials, he noted.
A large-scale, hormone-therapy based clinical trial in (Women’s Health Initiative) was conducted involving 2157 women aged between 65 and 80 years. The participants were annually assessed for thinking and memory skills over six years. The plasma concentration of omega-3 fatty acids were assessed from the initial stages through the end of the study.
No clinically significant difference in terms of memory skills among the women with high and low plasma levels of omega-3 fatty acids. No observed difference in progressive cognitive decline between the two groups.
