Contaminated diet contributes to phthalate and bisphenol A exposure

When the researchers tested the participants’ urinary concentrations of metabolites for phthalates and BPA, they got surprising results. The researchers expected the levels of the metabolities to decrease in those adults and children eating the catered diet.

Instead, the opposite happened. The urinary concentration for phthalates were 100-fold higher than the those levels found in the majority of the general population. The comparison comes from a study conducted by the National Health and Nutrition Examination Survey. This is a program of studies managed by the Centers for Disease Control and Prevention and designed to assess the health and nutritional status of adults and children in the United States.

The concentrations were also much higher for children as compared to the adults. The researchers then tested the phthalate concentrations in the food ingredients used in the dietary intervention. Dairy products—butter, cream, milk, and cheese—had concentrations above 440 nanograms/gram. Ground cinnamon and cayenne pepper had concentrations above 700 ng/g, and ground coriander had concentrations of 21,400 ng/g.
