Assessing the Evidence Around Perfluoroalkyl Substances

For approximately the past decade, scientists have started to wonder about potential hazards that could be posed to human health from chemicals collectively known as perfluoroalkyl substances (PFAS). These chemicals are widespread in the environment globally—they have been used in manufacturing products such as food packaging and textile coatings since the 1950s, and are now detectable in the food chain, and even in dust and dirt. Since these chemicals can accumulate in the body, researchers are studying how they might be passed from mother to infant. This appears to happen to some extent via the placenta and to a lesser extent via human milk. Such findings should not dissuade mothers from breastfeeding, however, because the levels of PFAS in infant formula have sometimes been found to be higher than those of human milk. Read More...
