HOW YOUR FOODS SPEAK TO YOUR DNA - INTRODUCTION TO NUTRIGENOMICS
Imagine if your breakfast could whisper directly to your DNA. Photo credit: Afolabi R.B. That is not science fiction. Every bite you eat is more than fuel, it is information. Nutrients and bioactive compounds in food interact with your body’s genetic material, influencing which genes are turned on or off, how cells function, and even how you age. This fascinating science is called nutrigenomics , the study of how diet and genes talk to each other. Researchers believe it could unlock the next big step in personalized nutrition, where diets are tailored not just to taste or calories, but to your DNA. What Exactly Is Nutrigenomics? At its central, nutrigenomics asks two questions: 1. How do nutrients and other food components influence gene activity? 2. Why do people respond differently to the same diet? Scientists use powerful “omics” tools (like genomics, proteomics, and metabolomics) to map how foods affect genes, proteins, and metabolites in the body. Think of it as a nutritional blue...
