A study of 48 adults found that four weeks on a vegan diet produced measurable changes in DNA methylation at approximately 800,000 sites, with evidence of altered inflammatory pathways and biological aging markers.
The study demonstrates that short-term dietary interventions produce quantifiable epigenetic changes, though clinical significance remains unclear. For engineers working in health data or computational biology, the analysis of 800,000 genetic loci across a controlled dietary study illustrates the scale of multi-omic data integration now feasible in nutrition research.

Researchers randomly assigned 24 participants to a vegan diet and 24 to a high-meat diet after a one-week standardized nutrition period.
Analysis of approximately 800,000 DNA methylation sites found changes in pathways associated with inflammation, cell growth, and biological aging.
The study authors call for larger and longer-term studies to determine whether the observed epigenetic changes are permanent.
