Long-term adherence to a Mediterranean Diet is associated with longer telomere length, a marker of biological age, particularly in women and those with specific PPARγ2 gene variants.
Maintaining a Mediterranean Diet over the long term may support cellular health markers associated with aging, such as telomere length, especially for women.
ModerateSupportsMEDIUM confidence
Other studies, in particular observational and ex vivo works, have reported that a long-term adherence to Mediterranean diet seems to be related to higher telomere length, activity. For example, Garcia Calzon et al. reported longer telomeres in women joining Mediterranean dietary approach, but not in males.
Why this rating
Based on observational and ex vivo studies; some gender differences observed.
