Scientists just figured out how many chemicals enter our bodies from food packaging

Researchers from Switzerland and other countries discovered that of the roughly 14,000 known chemicals in food packaging, 3,601 — or about 25 percent — have been found in the human body, whether in samples of blood, hair or breast milk. Those chemicals include metals, volatile organic compounds, per- and polyfluoroalkyl substances or PFAS, phthalates and many others known to disrupt the endocrine system and cause cancer or other diseases. Advertisement “There are known hazardous chemicals that are known to be linked with adverse human health outcomes,” said Jane Muncke, the chief scientific officer of the Food Packaging Forum and one of the paper’s authors. “And these chemicals leach out of packaging.” Scientists have known for many years that chemicals can spill out of food packaging into the food itself. High temperatures can cause chemicals to leach more quickly into food, which is why scientists recommend avoiding microwaving food in takeout containers. Foods that are high in fat or high in acidity also tend to absorb more chemicals from their packaging, as do foods that are tucked into smaller containers — the more cramped the container, the more contact it has with the food inside. “They served the salad with a 15 milliliter little plastic bottle with olive oil and vinegar that you could pour over it,” she said. “I thought, ‘Well, I’m not doing that.’” To conduct their analysis, scientists made an inventory of the chemicals known to be in food packaging or food processing equipment, and then searched global tissue databases for evidence that the chemicals had been found in the human body. “We don’t think about how the (mostly) plastic packaging adds chemicals to our food, but it’s an important source of human exposures,” R. Thomas Zoeller, an emeritus professor of biology at the University of Massachusetts at Amherst who was not involved in the research, said in an email. “This is an early indication that harmful chemicals — largely unregulated — are making it into the human population.” Advertisement Most of the chemicals leaching from food packaging come from plastics, but not all of them. “And I know that’s a hard one to stomach.” Recycling paper, cardboard or plastic for food packaging leads to nonfood grade inks mixed in next to food, she explained, adding to the chemical risks. – This Summarize was created by Neural News AI (V1).
