Introduction: The prevalence of aging-related pathologies has increased considerably. Nutrition is an important modifiable risk factor. Objective: Evaluate the elderly cognitive status and consumption frequency of foods rich in bioactive compounds and antioxidant nutrients. Methods: Elderly people from the Paraná southwest region participated in the research. Sociodemographic and clinical data were collected. Cognitive status was assessed using the Mini Mental State Examination (MMSE); the consumption of fruits, vegetables, legumes and oilseeds was assessed using a food consumption frequency questionnaire. Data were analyzed using descriptive statistics and logistic regression. Sample composed of 82 elderlies, predominantly female, with low education and income. The assessment of cognitive status and independence in performing daily activities indicated that 20.7% of the sample presented cognitive decline and 13.4% were dependent on performing daily activities. Results: The elderly evaluated presented low regular consumption of fruits (75.6%), vegetables (65.9%), legumes (67.1%) and especially oilseeds (8.5%). In the logistic regression analysis model adjusted for sex, age, living arrangements, income and education, the elderly who presented irregular consumption of vegetables were 5.04 times more probable to develop cognitive decline, while in the model that included, in addition to the aforementioned variables, physical activity and clinical risk factors for cognitive decline, they were 6.19 times more probable. Conclusion: The present study revealed that the sample presented significant percentage of cognitive decline, low regular consumption of varied foods from the groups of fruits, vegetables, legumes and oilseeds, as well as irregular consumption of vegetables influenced greater chances of elderly people presenting cognitive impairment.
