A 49-person pilot study found higher levels of two mitochondrial microproteins among older adults who reported closer adherence to a Mediterranean eating pattern.

Three things to remember

  • The cross-sectional study involved 49 patients with atrial fibrillation.
  • Higher adherence tracked higher Humanin and SHMOOSE blood levels.
  • The study cannot show that the diet caused those biological differences.

Health note: This was a small, cross-sectional convenience sample. It identifies associations and does not test whether changing diet raises these proteins or prevents disease.
