Background: Vascular aging is the main pathogenic factor for heart and cerebrovascular disease. It is a critical challenge to prevent vascular aging in the rapidly aging Japanese society. Objective: This study was carried out to examine the impact of dietary habits on the progression of vascular aging in middle-aged and elderly Japanese individuals. Participants: Subjects were 16 healthy males and females aged 63 to 72 years who gave consent to participate in the present study. Measurements: Vascular aging was evaluated by the second derivative of the fingertip photoplethysmogram, and the subjects were divided into two groups: Group I (vascular age was older than actual age) and Group II (vascular age was younger than actual age). Subjects took photos of all food dishes consumed for 7 days to investigate their dietary habits. We collected information of types of foods and the amounts from the photos, and entered this information into a Food Frequency Questionnaire based on Food Group (FFQg) to analyze the data. Results: Group II showed significantly greater (p < 0.05) intakes of polyunsaturated fatty acids (Group I, 10.3 ± 1.9 g/day; Group II, 13.2 ± 2.0 g/day), n-3 fatty acids (Group I, 2.3 ± 0.4 g/day; Group II, 2.7 ± 0.3 g/day), and n-6 fatty acids (Group I, 7.9 ± 1.6 g/day; Group II, 10.5 ± 1.9 g/day). Despite no significant difference in the intake of seafood (Group I, 95.4 ± 33.7 g/day; Group II, 98.8 ± 29.5 g/day) containing large amounts of n-3 fatty acids, Group II showed a significantly greater (p < 0.05) intake of soybeans and processed soybean products (90.9 ± 32.7 g/day) than Group I (52.9 ± 24.8 g/day). Conclusion: Intake of soybeans and processed soybean products was considered most effective in preventing the progression of vascular aging in the middle-aged and elderly subjects who participated in this study.
