An analysis of the endocrine disrupting chemicals in Old Order Mennonite women in mid-pregnancy determined that they have much lower levels in their systems than the general population. Mennonites eat mostly fresh, unprocessed foods, farm without pesticides, and use few or no cosmetics or personal care products. One woman who had reported using hairspray and perfume had high levels of monoethyl phthalate, while the other women all had levels below detection. Three women who reported being in a car or truck within 48 hours of providing a urine sample had higher levels of diethylhexyl phthalate which is found in polyvinyl chloride, and is used in car interiors.
