You Are What Your Grandmother Ate
December 07, 2006
You may have read already about the research showing that the diet of a mother can have an influence on a specific gene for at least two generations.
This study on mice looks at "epigenetic" changes made to DNA, involving genes that can be silenced or activated based on exposure to chemicals.
Half of the mice in the study were fed a nutrient-enriched diet, while the control group ate a standard diet. Exposure to those high amounts of nutrients in the womb changed the coats of the mice offspring from golden to dark brown fur, while the offspring of the control group remained unchanged.Not only that, but the children of the darker-coated mice were similarly affected; they also had dark brown fur.
