Abstract
Objective Omega-3 polyunsaturated fatty acids (PUFAs) play a crucial role in maintaining and improving cognitive function and brain health. The aim of this study was to assess the association between omega-3 PUFA intake and cognitive function in middle-aged and older adults in Saudi Arabia.Methods Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). The frequency and quantity of omega-3 PUFA intake were assessed using an omega-3 food frequency questionnaire.Results A total of 175 participants were recruited for this study. Participants in the lowest omega-3 PUFA tertile group scored significantly lower in the visuospatial/executive and attention cognitive domains (p < 0.05). After adjusting for confounders, the higher intake of alpha-linolenic acid (ALA) was significantly associated with higher scores in the visuospatial/executive domain (p = 0.02) and the higher intake of docosahexaenoic acid (DHA) was significantly associated with higher scores in the attention domain (p = 0.04). The participants who did not consume walnuts showed a significant lower MoCA score than those who did (p = 0.005). No significant differences were found with other omega-3 PUFA sources.Conclusion Higher intake of omega-3 PUFAs was positively associated with visuospatial/executive and attention cognitive functions in middle-aged and older adults.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
