“We are what we eat,” as the old adage says. “If you eat a hamburger one day, then its atoms and molecules will end up making your cell walls and different organs and tissues,” explains Logan McCarty, a lecturer on chemistry, chemical biology, and physics at Harvard University. For humans, as for other animals, it is essential to replace regularly the atoms and molecules in the body, and the food that we ingest supplies these atoms and molecules to fuel indispensable chemical processes and generate new cells.
Food is related to cellular division for an elegant reason: cells suffer damage over time, and division continuously replaces the old and dying cells with new ones. Mitosis and meiosis, the two different division processes, cannot create something from nothing. So the body incorporates new atoms and molecules from our food into dividing cells to generate fresh ones.
