Abstract:

Objectives: 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. This study was carried out to examine the impact of dietary habits on the progression of vascular aging in elderly Japanese individuals. Materials and Methods: Subjects were 12 healthy males and females aged 63 to 71years who gave consent to participate in the present study. 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 younger than actual age over 10 years, n=6) and Group II (vascular age was almost actual age which is within 5 years, n=6). Subjects took photos of all 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 I showed significantly greater (p < 0.05) intakes of protein (Group I, 77.0 ± 6.0 g/day; Group II, 64.0 ± 11.7 g/day), polyunsaturated fatty acids (Group I, 13.5 ± 2.3 g/day; Group II, 10.5 ± 2.2 g/day), iron (Group I, 8.1 ± 0.9 mg/day; Group II, 6.7 ± 1.1 mg/day), and zinc (Group I, 8.2 ± 0.8 mg/day; Group II, 7.2 ± 0.9 mg/day). Also Group I showed significantly higher body mass index (BMI, Group I, 23.8 ± 2.1 m2/kg; Group II, 20.5 ± 1.1 kg/m2). Despite no significant difference in the intake of seafood (Group I, 108.0 ± 36.0 g/day; Group II, 99.5 ± 38.0 g/day) containing large amounts of n-3 fatty acids, Group I showed a significantly greater (p < 0.05) intake of soybeans and processed soybean products (93.0 ± 24.8 g/day) than Group II (56.0 ± 28.0 g/day). Conclusion: Intake of soybeans and processed soybean products was considered the most effective measure for preventing the progression of vascular aging in the elderly subjects who participated in this study.
