A new study shows that women who consume trans fat from snack foods and fast food places may give birth to bigger babies.
The study did not prove that trans fats alone boost fetal growth. But researchers found a link between newborn size and a mother's cholesterol levels that are affected by trans fats.
Bigger babies often must be delivered by caesarean section and they may have increased risk of diabetes and heart disease later in life.
The study appears in the American Journal of Clinical Nutrition.
