Vegan Diet Linked to Lower Biological Age: Study Finds

A recent study published in BMC Medicine found that an eight-week vegan diet could lower biological age by affecting DNA methylation. The research involved 21 pairs of identical twins, showing positive changes in heart, liver, inflammatory, and metabolic systems for vegans, though caution is advised due to potential nutrient deficiencies.

A recent study published in BMC Medicine has found a link between an eight-week vegan diet and a reduction in biological age. Researchers from Stanford University examined the molecular effects of a plant-based diet, which excludes all animal products, on gene behaviour without altering the DNA itself.

Specifically, the study focused on 21 pairs of adult identical twins, with one twin following a vegan diet and the other an omnivorous diet. After eight weeks, the team observed younger hearts, livers, inflammatory markers, and metabolic systems in the vegan participants. These benefits, however, were not observed in the omnivorous group.

While the study's results are promising, experts like Tom Sanders caution that the diet can lead to micronutrient deficiencies, such as vitamin B12 deficiency, which could have long-term adverse effects on nerve and bone health.
