Topic: Risk, prevention and care in population studies
Background/aims To investigate associations of the Mediterranean diet (MeDi) components and the MeDi score with mild cognitive impairment (MCI). Methods Participants (aged 70-89 years) were clinically evaluated to assess MCI and dementia, and completed a 128-item food frequency questionnaire. Results 163 of 1,233 nondemented persons had MCI. The odds ratio of MCI was reduced for high vegetable intake [0.66 (95% CI = 0.44-0.99), p = 0.05] and for high mono- plus polyunsaturated fatty acid to saturated fatty acid ratio [0.52 (95% CI = 0.33-0.81), p = 0.007], adjusted for confounders. The risk of incident MCI or dementia was reduced in subjects with a high MeDi score [hazard ratio = 0.75 (95% CI = 0.46-1.21), p = 0.24]. Conclusion Vegetables, unsaturated fats, and a high MeDi score may be beneficial to cognitive function.

Key findings
- Results 163 of 1,233 nondemented persons had MCI.
Why it matters
High vegetable intake and a high ratio of mono- plus polyunsaturated fats to saturated fats were associated with lower odds of mild cognitive impairment. A high Mediterranean diet score was linked to reduced risk of incident MCI or dementia, but this finding was not statistically significant.
