| Research Abstract |
This study was conducted to verify the relationship between fatty acids and cognitive function from the longitudinal data of middle-aged and elderly community residents, aiming to prevent cognitive decline through the diet. The relationship of fatty acid intake (45 types) and serum fatty acid concentration (24 fractions) with cognitive function was thoroughly investigated. Out of the various fatty acids, low serum docosahexaenoic acid (DHA) was found to be at high risk of cognitive decline after 10 years. Since there is a positive correlation between DHA intake from the diet and serum DHA concentrations, we found that there is a possibility that consumption of DHA-rich, blue fish could prevent cognitive decline.
