Healthy young people consume more omega-3 fatty acids, which can help improve and enhance memory.
There is also increasing evidence that omega-3 fatty acids (ω-3FA), carotenoids and vitamin E can improve human cognitive ability
.
However, their effect on cognition has not been studied in healthy elderly individuals
Healthy young people consume more omega-3 fatty acids, which can help improve and enhance memory.
Researchers require healthy elderly people over 65 to take 1 gram of fish oil daily (430 mg of docosahexaenoic acid, 90 mg of eicosapentaenoic acid), 22 mg of carotenoids (10 mg of lutein, 10 mg meso-zeaxanthin, 2 mg zeaxanthin) and 15 mg vitamin E were treated, and a group of similar elderly patients were recruited for placebo-controlled treatment
.
The results of the study showed that after 24 months of supplementation with relevant nutritional preparations, compared with individuals receiving placebo (n=30; age 69.
77±3.
74 years; 70% women), although the cognitive load of working memory tasks increased, The memory performance of patients in the treatment group was better than that of the placebo group
.
Compared with placebo, was also observed in the treated group concentration of tissue carotenoid, xanthophyll carotenoid concentrations in serum and plasma concentrations of ω-3FA statistical learning significantly improved, therefore, supplementation Omega-3 fatty acids, Carotene and vitamin E have certain benefits
statistics
The results of this study support a biologically sound basic principle that these nutrients act synergistically in a dose-dependent manner to improve the working memory of cognitively healthy elderly people

Increasing the nutritional intake of carotenoids and omega-3FA may help reduce the risk of cognitive decline and dementia in later life
