You are what your father ate, too: Paternal diet affects lipid metabolizing genes in offspring, research suggests

ScienceDaily (2010-12-24) -- We aren't just what we eat; we are what our parents ate, too. That's an emerging idea that is bolstered by a new study showing that mice sired by fathers fed on a low-protein diet show distinct and reproducible changes in the activity of key metabolic genes in their livers. Those changes occurred despite the fact that the fathers never saw their offspring.
