Researchers may have solved a vexing mystery as to why parabens contamination in humans has been so pervasive in recent studies: Parabens
are increasingly contaminating our food supply.
Researchers from the New York State Department of Health and the Department of Environmental Health Sciences, along with the University of New York at Albany have determined in a study of foods purchased from local markets that much of the U.S. food supply is contaminated with parabens - a group of chemicals thought previously to produce exposure in humans through the skin in cosmetics and lotions containing preservatives.
This likely explains an increasing body of evidence showing that humans have much higher blood and urine concentrations of parabens than could be explained with the use of body lotions and cosmetics.
The researchers tested 267 samples of food collected from stores and markets around Albany New York. These included juices, soft drinks, alcoholic beverages, infant formula, dairy products such as milk, yogurt, cheese and ice cream, oils, fats, breads, flours, rice, pasta, corn, fruits, baked goods, meats, shellfish and seafoods and many others. Once collected and categorized, the foods were analyzed using liquid chromatography and mass spectrometry - which measure the biochemical content of the food from the molecular level.
Five different types of parabens were tested. These were butyl-parabens, benzyl-parabens, propyl-parabens, methyl- parabens, and ethyl-parabens.
