from medicalnewstoday.com: Many of the synthetic chemicals involved in packaging and storing the food we eat can leak into it, potentially harming our long-term health, say environmental scientists in a paper published in the Journal of Epidemiology and Community Health. Although some of these chemicals are regulated, people come into contact with them almost every day through packaged or processed foods. The authors of the commentary note that exposure is low, but it is chronic, as many of us eat such foods throughout our lives.
