Weight Gain in Moms Lowers Toxins in Newborns
New Study for Expectant Mothers
Many expectant mothers try to know about everything they put into and onto their bodies as multiple studies are finding that infants are exposed to toxins during pregnancy. A new study of 325 expectant mothers has determined that the baby’s exposure to toxins in the womb decreases when the mother’s weight gain during pregnancy approaches the guidelines recommended by the Institute of Medicine (IOM) in 2009. Women that are underweight at the start of pregnancy are advised to gain between 28 and 40 pounds, women of a healthy weight 25 to 35 pounds, overweight women 15 to 25 pounds and obese women 11 to 20 pounds.
The researchers found that expectant mothers with a gestational weight that meets or exceeds the IOM guidelines gave birth to infants with reduced toxin levels. In their analysis of the umbilical cord blood of mothers from Spain, the researchers tested for 14 pesticides and 21 other environmental toxins, including seven polychlorobiphenyls (PCB).
