It’s long been known chemicals can seep into food when it’s made, packaged, processed and stored, but a new study shows just how many of those chemicals make their way into the human body. Researchers from multiple countries came together to study 14,000 chemicals known to be used in food packaging. They found 3,601 of them – about 25% – can be found in the human body.
What’s more, 79 of the chemicals found are known to cause cancer, genetic mutations, and reproductive and endocrine issues, among other health concerns.
Researchers say most of the chemicals leeching from food packaging come from plastics. Chemicals identified in the study include BPA, PFAS and phthalates, but plastics are not the only concern.
One of the study’s authors pointed to recycled food packaging, specifically, because the recycling process allows non-food grade inks to be exposed to the food you eat.
The study’s authors also said while only 79 of the chemicals found in the human body are known to cause health issues, more of the chemicals may be harmful, but we just don’t know it yet. They also note that while food packaging products may comply with government regulations, that doesn’t necessarily mean they are completely safe.
There are ways to mitigate exposure though, like avoiding microwaving food in takeout containers because high temperatures can cause the chemicals to get into food more quickly. Scientists also say foods that are high in fat or acidity also tend to absorb more chemicals from their packaging.
Another good piece of advice given is to avoid small cramped food containers. The more cramped the container, the more contact it has with the food inside.
