Nutrigenomics is an area of epigenomics that explores and defines the rapidly evolving field of diet-genome interactions. Lifestyle and diet can significantly influence epigenetic mechanisms, which cause heritable changes in gene expression without changes in DNA sequence. Nutrient-dependent epigenetic variations can significantly affect genome stability, mRNA and protein expression, and metabolic changes, which in turn influence food absorption and the activity of its constituents. Dietary bioactive compounds can affect epigenetic alterations, which are accumulated over time and are shown to be involved in the pathogenesis of age-related diseases such as diabetes, cancer, and cardiovascular disease. Histone acetylation is an epigenetic modification mediated by histone acetyl transferases (HATs) and histone deacetylases (HDACs) critically involved in regulating affinity binding between the histones and …
