Moms who eat high-fat diet before, during pregnancy 'program' babies to be fat, at risk
Date:9/16/2011

ated 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.

These changes in body composition and organ size occurred before the female mice eating a high-fat diet became obese, the researchers report. And even when the females were not obese, eating a high-fat diet prior to and during pregnancy "programmed" their unborn babies to have increased body fat and smaller livers at birth. Fortunately, the researchers found, switching to a low-fat diet just during pregnancy prevented the infants from accumulating excess fat mass in utero and also prevented their having smaller livers.

"These findings demonstrate that changing to a low-fat diet during pregnancy minimizes the harmful effects of maternal obesity on the newborn's body composition, potentially reducing the child's risk of developing obesity and related diseases later in life," said Krasnow.
