Association of omega-3 polyunsaturated fatty acids intake and cognitive function in middle-aged and older adults.
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.
期刊介绍：
Nutritional Neuroscience is an international, interdisciplinary broad-based, online journal for reporting both basic and clinical research in the field of nutrition that relates to the central and peripheral nervous system. Studies may include the role of different components of normal diet (protein, carbohydrate, fat, moderate use of alcohol, etc.), dietary supplements (minerals, vitamins, hormones, herbs, etc.), and food additives (artificial flavours, colours, sweeteners, etc.) on neurochemistry, neurobiology, and behavioural biology of all vertebrate and invertebrate organisms. Ideally this journal will serve as a forum for neuroscientists, nutritionists, neurologists, psychiatrists, and those interested in preventive medicine.
