High adherence to a Mediterranean diet is associated with longer leukocyte telomere length (LTL) and higher PBMC telomerase activity in elderly individuals, independent of age, gender, and smoking status.

Adhere closely to a Mediterranean dietary pattern (high intake of vegetables, legumes, fruits, cereal, fish, and monounsaturated fats; low intake of meat and dairy) to support telomere maintenance and potentially slow cellular aging. This involves prioritizing plant-based foods and healthy fats while limiting processed meats and dairy.

High adherence group showed longer LTL (p = 0.003) and higher telomerase activity (p = 0.013) compared to others... MDS was independently associated with LTL (p = 0.024) and telomerase activity levels (p = 0.006).

Why this rating

Observational cohort study with a relatively small sample size (n=217) and cross-sectional design limits causal inference, though statistical adjustments are robust.
