These studies are too vague. The participants in the vegan group avoided all animal products. What exactly did they eat or not eat from plant-based sources? Some interesting points were made in the study as outlined below.
-Although certain studies have indicated potential positive impacts of specific components of a vegan diet, such as heightened intake of vegetables and fruits, on epigenetic aging, concerns have been raised regarding potential deficiencies in essential “epi-nutrients” necessary for effective epigenetic regulation [7]. Notably, vitamins and nutrients, including vitamin B12, vitamin B+, choline, vitamin D, omega-3 fatty acids, and zinc, are among the concerns associated with a vegan diet, as their availability may be compromised.
-Furthermore, the vegan cohort exhibited lower caloric intake, consumed less saturated fats, more polyunsaturated fats, and more fiber than the omnivorous group, suggesting these as the potential drivers of age reductions, rather than the vegan diet only [21]
Additionally, this was an 8-week study. The levels of vitamins like B-12 were measured in both the omnivore and vegan groups and showed similar results, likely due to existing stores in the body. However, for long-term adherence to a strict vegan diet, the vegan group would need to supplement with at least Vitamin B12.
Eating a vegan diet for eight weeks is associated with reductions in biological age estimations based on levels of DNA methylation—a type of chemical modification of DNA (known as an epigenetic modification) that alters gene expression but not DNA itself.
