Environmental pollutant linked with overweight:

Levels of the environmental pollutant perfluorooctanoic acid (PFOA) that mothers had in their blood during pregnancy increased the risk of obesity in their daughters at 20 years of age. The findings come from a recent study of Danish women in which the Norwegian Institute of Public Health participated. The study indicates that factors such as environmental pollutants, in addition to diet and physical activity, play a role in the obesity epidemic seen today.

Children near DuPont plant exposed to more PFOA than moms.

The study was undertaken by scientists who have spent seven years trying to determine whether the DuPont chemical is making people sick in the Mid-Ohio Valley.

The discovery about moms and their children comes as scientists elsewhere linked the chemical, known as PFOA, and related chemicals to reduced effectiveness of childhood vaccinations. The compounds are used to manufacture Teflon cookware, food packaging and other products
