OBJECTIVE:   To examine whether adherence to the Mediterranean diet was associated with longer telomere length, a biomarker of aging.

DESIGN:   Population based cohort study.

SETTING:   Nurses’ Health Study, an ongoing prospective cohort study of 121,700 nurses enrolled in 1976; in 1989-90 a subset of 32,825 women provided blood samples.

PARTICIPANTS:   4676 disease-free women from nested case-control studies within the Nurses’ Health Study with telomere length measured who also completed food frequency questionnaires.

MAIN OUTCOME MEASURE:   Association between relative telomere lengths in peripheral blood leukocytes measured by quantitative real time polymerase chain reaction and Alternate Mediterranean Diet score calculated from self reported dietary data.

RESULTS:   Greater adherence to the Mediterranean diet was associated with longer telomeres after adjustment for potential confounders. Least squares mean telomere length z scores were -0.038 (SE 0.035) for the lowest Mediterranean diet score groups and 0.072 (0.030) for the highest group (P for trend = 0.004).
