The results of the study indicate that a diet free of animal products can lead to a decrease in biological aging rates, benefiting the heart, liver, and hormonal and inflammatory systems. This suggests that the temporary change in diet has a positive impact on the body's aging process.
The use of epigenetic biomarker proxies (EBPs) highlights their potential for assessing dietary impacts and facilitating personalized nutrition strategies for healthy aging.
The vegan diet participants not only showed differences in DNA markers but also lost an average of two kilograms more compared to those on an omnivorous diet. This makes it challenging to dismiss the impact of caloric restriction or weight loss on observed biological aging.
It is important to note that the study had a relatively small sample size and did not address the potential risk of nutrient deficiencies that may arise from a plant-based diet in the long run. Furthermore, the study received partial funding from Beyond Meat, a company specializing in plant-based meat alternatives, and the Vogt Foundation, which supports projects promoting plant-based products and animal welfare.
The researchers themselves acknowledge that the connection between dietary variations and biological aging remains uncertain. Currently, there is no concrete evidence supporting the claim that vegans live longer.
Nevertheless, the study provides valuable insights into how dietary changes can quickly yield positive effects on the body. This research builds upon a previous study from last year, which demonstrated that an eight-week vegan diet could improve cardiovascular health.
The researchers suggest that future studies should investigate the prolonged effects of vegan diets on epigenetic health and overall well-being, emphasizing the importance of adequate nutrient supplementation.
