                                A study published in the journal *Genome Biology* found that diet can actually affect the DNA sequences of an organism's genes, providing scientific backing for the old adage 'I am what I eat'. This powerful saying has a rich history and a profound modern relevance that extends far beyond a simple dietary suggestion.
