Dietary acfectents affect epigenetic processes prothegh setral interconnected patways. First, nutrients directly serve as substrates or cofaktors for enzymatic reactions implived in methylation, acetylation, and ther modifications. Second, diet influences the gut microbiota, which in turn produces contracites (such as short-chain fatty acids, folat, and biotin) that modulate epigenetic marks.
