Abstract

Purpose

Cognitive decline and dementia are major causes of disability. Research has suggested a relationship between dietary intake and memory problems in individuals. This study aims to examine the dietary histories of participants with newly diagnosed memory problems.

Design/methodology/approach

A total of 285 subjects (129 cases and 156 controls) were included in this retrospective case−control study. This paper used a food frequency questionnaire to determine the intake of dietary food groups in the previous year and a general questionnaire to assess food habits. The strength of the association between dietary history and memory problems was assessed using logistic regression and Pearson’s tests.

Findings

In this study, 73% of participants had a lower middle income and consumed less than the recommended number of meats, fruits and vegetables (1.2, 1.8 and 0.99 units/day, respectively). Participants with memory problems were more likely to take supplements than those without (P = 0.01). There was no significant difference in energy intake between the case and control groups (1634 Kcal vs 1656 Kcal). The results of the logistic regression showed that consuming any of the food groups in the previous nine months was not associated with memory problems. However, the Pearson test showed that an increase in the consumption of high-quality protein and vegetables had a slightly nonsignificant relationship with a decrease in the severity of memory disorder.

Originality/value

It is safe to suggest consuming adequate amounts of high-quality protein and affordable protein from sources such as dairy products, meats and vegetables. Research is insufficient to recommend the use of dietary supplements as a means of preventing memory disorders.
