The rapid technological advancements achieved in the last years have boosted the progressive identification of age-associated epigenetic changes. These studies not only contribute to shed light on the molecular basis of ageing and age-related diseases but, given the plasticity of epigenetic modifications, also provide the basis for anti-ageing interventions to counteract the onset of age-related diseases. In this review we will discuss nutritional interventions as a promising approach that can positively counteract epigenetic changes associated with ageing and promote the health for the elderly. First, we will give an overview of age-associated epigenetic signatures, focusing on DNA methylation. Then, we will report recent evidences regarding the epigenetic changes induced by nutritional interventions in the adulthood (referred as “epigenetic diets”), such as (i) caloric/dietary restriction, (ii) diet supplementation with …
