In a study featured in Neurology, 1,613 subjects were examined between the ages of 45 and 70, testing the correlation between Omega-3 consumption and the preservation of cognitive abilities. Mental functioning was gauged on multiple measures by researchers (memory, psychomotor speed, higher-level information processing and overall cognition), and participants completed a food consumption questionnaire to record their eating patterns, especially as their diets related to intake of fatty fish.

Consumption of long-chain polyunsaturated Omega-3 fatty acids derived from fish was positively associated with a reduced risk of mental impairment, both on measures of overall cognitive function and psychomotor speed. Researchers also noted a significant correlation between higher consumption rates of cholesterol (saturated fats) and an increased risk of impaired memory and cognitive flexibility.

The researchers concluded that Omega-3’s may benefit cognitive performance due to their anti-inflammatory properties. The researchers further speculate that the diminished cognitive performance associated with lower intake of Omega-3’s may be a predictor of Alzheimer’s Disease later in life.
