Adopting a plant-based diet may help reduce biological age
New research from Stanford University suggests that adopting a plant-based diet may help slow the progression of biological age. The study, published in the journal BMC Medicine, reveals the link between dietary habits and DNA methylation by comparing the effects of a plant-based diet with an omnivore diet, and suggests that a plant-based diet may have a positive regulatory effect on biological age. .
The so-called biological age is different from what we usually call age. It reflects the true state of human body organ functions, inflammatory markers, metabolic functions and other biomarkers. DNA methylation is a key process in regulating genes related to aging and disease. It adds small molecule methyl groups to DNA to turn specific genes on or off, affecting cell function.
A team of researchers from Stanford University tracked 21 pairs of adult identical twins to assess biological age by analyzing DNA methylation levels in their blood samples. The results showed that twins who adhered to a plant-based diet for eight weeks experienced a decrease in biological age, while twins who adhered to an omnivorous diet did not show the same effect.
The study also found that the twins who ate a plant-based diet experienced improvements in biological age in their heart, hormones, liver, and inflammation and metabolic systems. This may be because plant-based diets are often rich in whole foods, such as nuts, legumes, seeds, fruits and vegetables, which are rich in antioxidants and have anti-inflammatory properties.
