Abstract

BACKGROUND: Individuals with exceptional longevity and their offspring manifest a lower prevalence of age-related diseases than families without longevity. However, the contribution of dietary habits to protection from disease has not been systematically assessed in families with exceptional longevity. OBJECTIVE:The aim of this study is to compare dietary patterns between individuals with parental longevity and individuals without parental longevity. METHODS: Dietary intake was evaluated using the Block Brief Food Frequency Questionnaire in 234 community dwelling Ashkenazi Jewish adults aged 65 years and older who were participants of the LonGenity study, which enrolls the offspring of parents with exceptional longevity (OPEL) and offspring of parents with usual survival (OPUS). RESULTS: OPEL constituted 38% of the subjects. The two groups had similar daily intake of total calories (1119 vs. 1218 kcal, p = 0.83), grams of cholesterol (141 g vs. 143 g, p = 0.19), and grams of sodium (1324 g vs.1475 g, p = 0.45), in OPEL vs. OPUS respectively. There were also no significant differences in the intake of other macronutrients, micronutrients, nutritional supplements and consumption of various food groups between OPEL and OPUS after adjustment for age and sex. DISCUSSION: A healthy diet is associated with a lower risk of several chronic diseases. Our study revealed that dietary intake did not differ between OPEL and OPUS; thus, pointing to the role of longevity genes in protecting from disease among individuals with familial longevity. CONCLUSION: The offspring of long-lived parents do not differ in their dietary patterns compared to individuals without parental longevity.
