| Outline of Final Research Achievements |
The present study aimed to clarify the effects of fatty acid intake on a cognitive decline which is exacerbated by insulin resistance and inflammation from a longitudinal study (NILS - LSA) among community dwellers.
As a result, (1) the level of glucose metabolism strongly correlated with the decline in intelligence/cognitive function rather than the inflammatory state, (2) fatty acid intake and blood fatty acid concentration did not inhibit the cognitive decline exacerbated by insulin resistance and inflammation,(3) the association between glucose metabolism and cognitive function was strongly influenced by lifestyles, such as physical activities, smoking habit and high blood pressure, rather than fatty acid.
These results indicate that fatty acid intake is not inhibitive for cognitive decline exacerbated by insulin resistance and inflammation, while adequate nutrition (fatty acid intake) to control sugar metabolism and obesity is effective for dementia prevention.
