Vegan diet reduces biological age

A recent study involving 21 pairs of identical twins reveals that adopting a vegan diet for just eight weeks can significantly reduce biological age, as measured by changes in DNA methylation. Researchers from Stanford University and TruDiagnostic found that participants on a vegan diet experienced decreases in their epigenetic age and improvements in the health of various organ systems, including the heart and liver. Despite these promising results, experts caution that the small sample size and short duration of the study limit the conclusions that can be drawn, particularly regarding long-term effects and nutritional adequacy. The study highlights the potential of diet to influence cellular health and aging, suggesting that even brief dietary changes may have meaningful impacts. However, it remains unclear how much of the observed benefits are due to weight loss versus dietary composition. Further research is needed to fully understand the implications of these findings and the role of diet in biological aging.
