One-Month Vegan Diet Changes Epigenetic Markers Linked to Aging and Inflammation

Researchers from the University of California, San Diego, and the University of Freiburg in Germany have reported that adopting a vegan diet for just one month can produce measurable changes in the body’s epigenetic profile, specifically in DNA methylation patterns. In a randomized clinical trial, participants were assigned either a plant‑based diet or a meat‑rich diet, and the resulting methylation changes were linked to pathways involved in immune function, metabolism, and cancer risk.

The study, published in *MedComm*, found that the vegan group exhibited methylation shifts associated with reduced inflammation and slower biological aging. These epigenetic modifications are thought to influence gene activity without altering the underlying DNA sequence, suggesting that dietary choices can quickly modulate molecular processes that underlie long‑term health outcomes.

The authors conclude that even short‑term dietary interventions can have rapid, biologically relevant effects on epigenetic regulation, highlighting the potential of nutrition as a modifiable factor in disease prevention and health promotion.
