Abstract

The purpose of this study was to verify whether Mediterranean diet, which proved to have a significant effect on preventing dementia for people aged 65 or older, could be well modified to be a Korean-style Mediterranean diet. This study was performed as a randomized-controlled trial for 6 weeks. Functional physical changes, cognitive scores, depression scores and dietary changes were all assessed. The walking speed (P<0.001) and the cognitive scores were statistically improved in only the experimental group (P<0.001), and the depression scores were also significantly improved in only the experimental group (P<0.01). The dietary intake showed a 30% improvement for consuming more than 7 cups per day of vegetables and fruits. When the participants were contacted four months after the end of the study, 90% of them said that the Korean-style Mediterranean diet was feasible and 100% said the nutrition interventions helped them maintain the diet during their daily lives. The results suggest that although the Mediterranean diet can be difficult to apply, any limitations of this healthy diet can be overcome.
