I found Crous-Bou, et al.’s (2014) study on the Mediterranean Diet and telomere length and finding that “greater adherence to the Mediterranean diet was associated with longer telomeres” to be fascinating (1). This brought to mind another recent study that might shine some more light on the connection between telomere length with the Mediterranean Diet and better health. According to Robin, et al (2014), “…telomere length regulates gene expression long before telomeres become short enough to produce a DNA damage response….” This could help explain how greater telomere length with the Mediterranean Diet might influence health outcomes. The area of regulation of gene expression and how this contributes to phenotype is a topic that is getting much attention in recent years and one that I find fascinating to read about.
