Abstracts

Objectives: This study aimed to determine the association between the frequency of fruit and vegetable consumption and cognitive function in older Taiwanese. Methods: We analyzed the 1999 and 2003 datasets of the ”Survey of Health and Living Status of the Elderly in Taiwan”. Subjects were 4440 ≥53-year-old Taiwanese men and women. The frequency of consumption of fruits and vegetables in 1999 was examined for its possible cross-sectional association with cognitive status and for a possible association with the risk of cognitive decline four years later. Cognitive status and cognitive decline were rated with the SPMSQ scale. A reduction of 2 SPMSQ points was designated as a decline. Results: In a regression model that controlled for gender, age, years of education, smoking, drinking, betel quid chewing, physical activity, leisure activity, intake of nutritional supplements (fish oil & lecithin), and illness (hypertension, diabetes, heart disease, stroke) and other possible confounders, the cross sectional analysis showed that more frequent consumption of fruits and vegetables (≥5 times/wk) was associated with a 31% reduction in cognitive impairment (OR = 0.69, 95 CI = 0.57-0.84, p = 0.001); the longitudinal analysis showed that those who consumed fruits and vegetables ≥5 times/wk had a 23% reduction in cognitive decline 4-years later when compared to those who consumed fruits and vegetables ≤4 times/wk (0.77, 0.59-0.99, p = 0.048). Other food categories such as meat and poultry, fish, seafood and dairy showed no significant associations. Conclusions: More frequent fruit and vegetable consumption was associated with a reduction in cognitive impairment and can protect against future cognitive decline. These results suggest that the intake of fruits and vegetables may offer protection against cognitive decline. The study also highlights the importance of diet in delaying aging-associated memory deterioration; however, these findings should be confirmed with more robust studies.
