Newborns of moms who ate high-fat diet have more body fat, smaller livers

Posted On: Sept. 27, 2011

Washington, Sept 17 (ANI): Result of a new study has found that babies born to moms who eat a high-fat diet before and during pregnancy have a higher fat mass and smaller livers than babies whose moms consume low-fat fare

Fortunately, scientists at Oregon Health and Science University Doernbecher Children's Hospital said, moms who switch to a low-fat diet during pregnancy considerably reduce the risk of these negative effects.

"One of the key findings here is that the offspring are born with a marked shift in body composition, away from lean mass and toward fat mass, prior to any dietary exposure in the offspring themselves," said principal investigator Stephanie M. Krasnow, Ph.D., a scientist in the Pape Family Pediatric Research Institute at OHSU Doernbecher Children's Hospital.

In the study, Krasnow and colleagues fed female mice either a low-fat or high-fat diet for six months, and allowed them to mate with male mice after 4, 12 and 23 weeks.

The females who ate a high-fat diet gained more body weight and had a higher fat mass than the females who ate a low-fat diet.

And on the day of birth, babies born to females who had consumed a high-fat food had more body fat, less lean mass, and smaller livers than the newborns of females that consumed low-fat food.

The findings have been published online in the American Journal of Physiology and Endocrinology Metabolism. (ANI)
