Review: Diet, epigenetic aging and age-related disease risk
This abstract reviews how the Mediterranean diet, caloric restriction and the ketogenic diet may influence epigenetic mechanisms linked to aging and chronic disease risk; it states that causality is not yet established. [1]
Automatic summary · not editorially reviewed
The key findings
The review links aging to epigenetic alterations such as changes in DNA methylation, acetylation and histone modification patterns. [1]
The abstract discusses the Mediterranean diet, caloric restriction and the ketogenic diet as key nutritional strategies that may affect epigenetic remodeling. [1]
Current evidence is described as supporting an association between diet quality and decelerated epigenetic aging, while causality still requires future research. [1]

Epigenetic changes and disease susceptibility in aging
The review links aging to epigenetic alterations, including changes in DNA methylation, acetylation and histone modification patterns. According to the abstract, these alterations accompany cellular decline and increased susceptibility to disease. The review examines the connection between aging-related diseases and epigenetic mechanisms.

Three diets and epigenetic remodeling in the review
The abstract discusses the Mediterranean diet, caloric restriction and the ketogenic diet as key nutritional strategies. It states that these interventions supply essential substrates and regulate enzymes central to epigenetic remodeling, thereby affecting gene expression networks involved in inflammation, metabolism and cellular stress responses. The review further states that such dietary patterns can attenuate cellular senescence and reduce chronic disease risk by correcting age-related epigenetic dysregulation.

Association evidence and open causality question
The abstract says current evidence supports an association between diet quality and decelerated epigenetic aging. It does not report study designs, sample sizes, follow-up periods or effect sizes. The authors state that future research is needed to establish causality and to develop personalized nutritional approaches for longevity and healthspan.

How to interpret this
This is an abstract; the full text was not reviewed. No study designs, sample sizes, follow-up periods or effect sizes are reported. The described dietary effects and the link to disease risk are presented as associations, not established causes.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
