Swedish researchers have determined that a five-week course of omega 3 PUFA fish oil has the potential to improve cognitive functions and cardio-metabolic risk factors in healthy, middle-aged to elderly adults.
In a study published in Nutrition Journal, 40 test subjects received either a placebo or a dietary supplement that contained 1,000 mg of fish oil (300 mg EPA, 210 mg DHA, 90 mg unspecified) five times per day. During the five weeks, subjects underwent tests evaluating cognitive performance, working memory and selective attention. They were also evaluated for physiological test variables including blood pressure, triglyceride, insulin and blood glucose levels. At the end of the five weeks, researchers determined the relationship between the outcome in cognitive tests and cardio-metabolic risk factors highlighted the importance of early dietary intervention to prevent cognitive decline secondary to cardio-metabolic disorders. “The dietary prevention strategy should preferably include fish in quantities to supply sufficient amounts of PUFA, in addition to other food groups with potential metabolic benefits, e.g., whole grain, low glycemic index foods, fruits, berries, vegetables and prebiotics,” they wrote.
