Abstract: The aim is to clarify the relationship between dietary habits and dementia status in the community-dwelling elderly aged 65 years and older. Self-administered questionnaires were sent to 2,069 elderly in March 2004 and 1,538 were returned by mail (response rate 74.3$\%$). The subjects answered frequency of dietary intakes of meat/poultry, soy products, eggs, oily fish, dairy products, fruits, vegetables, fats and alcohol. We classified analysis subjects into three groups according to intellectual activity scores: people with dementia (PWD), people with probable dementia (PPD) and cognitively intact people (CIP). The chi-square, Kruskal-Wallis, Mann-Whitney U and Bonferronis multiple comparison tests were performed. Significance was set at 0.05. The Kruskal-Wallis and Mann-Whitney U tests revealed significant differences in women between CIP and PPD in all dietary items and between CIP and PWD in soy products, oily fish and vegetables. Men showed significant differences between CIP and PPD in fruits and alcohol and between CIP and PWD in fats and alcohol. The conclusion is that dietary items above including moderate amount of alcohol are recommended to prevent or delay the onset of dementia by Alzheimers Society. The results suggest that CIP womens health behavior was better than mens, supporting the recommended foods as healthy diet.
