Everyone knows that what mom eats when pregnant makes a huge difference in the health of her child. Now, new research in mice suggests that what she ate before pregnancy might be important too. According to a new research report published online in The FASEB Journal, what a group of female mice ate -- before pregnancy -- chemically altered their DNA and these changes were passed to her offspring. These DNA alterations, called "epigenetic" changes, drastically affected the pups' metabolism of many essential fatty acids.
These results could have a profound impact on future research for diabetes, obesity, cancer, and immune disorders.
"As parents, we have to understand better that our responsibilities to our children are not only of a social, economical, or educational nature, but that our own biological status can contribute to the fate of our children, and this effect can be long-lasting," said Mihai Niculescu, M.D., Ph.D., study author from Nutrition Research Institute at the University of North Carolina at Chapel Hill, in Chapel Hill, N.C. "My hope is that, along with many other scientists, we will reveal this tight biological relationship between us as parents, and our children, and how we can improve the lives of our children using our own biological machinery."
