Fish consumption, intake of fats and cognitive decline at middle and older age: The Doetinchem Cohort Study

I bet nothing here will ever make it into a diet protocol in your hospital or take home instructions post-stroke. Because your doctor and hospital don't ever read and translate research findings into usable protocols. Why would they? It would mean actually doing some difficult work summarizing the thousands of research articles on food. They would rather wait for SOMEONE ELSE TO SOLVE THE PROBLEM.  You are screwed once again.

The Doetinchem cohort study was carried out to get insight into the effect of fish and fat consumption in the prevention of accelerated cognitive decline with aging, they tested relationship amongst fish and different fat consumption and 5–year change in cognitive functions. It was concluded that the higher cholesterol consumption was detrimental, while higher a-linolenic acid (ALA) consumption was beneficial for maintaining cognitive function with aging, already at middle age.

Methods

• In 2612 men and women of the Doetinchem Cohort Study, aged 43–70 years at baseline, dietary consumption (including fish consumption) and cognitive function were evaluated at baseline and at 5–year follow–up.
• In this study, average fish intake (frequency) and consumption (as energy percentages) of total fat, saturated, mono unsaturated, and polyunsaturated fatty acids (PUFA), linoleic, docosahexaenoic, eicosapentaenoic, and a–linolenic acid (ALA), and cholesterol were averaged over baseline and follow–up.
• Consumption were studied in relation to 5–year change in global cognitive function, memory, information processing speed, and cognitive flexibility, utilizing ANCOVA and multivariate linear regression investigations.

Results

• In this study, they observed no consistent relationship between (fatty) fish intake and cognitive decline.
• They found higher cholesterol consumption was related to faster cognitive decline (p < 0.05).
• Higher n–3 PUFA ( particularly ALA) consumption was related to slower decline in global cognitive function and memory (p < 0.01).
• Consumption of other fatty acids were not related to cognitive decline
