Welcome to r/science! This is a heavily moderated subreddit in order to keep the discussion on science. However, we recognize that many people want to discuss how they feel the research relates to their own personal lives, so to give people a space to do that, personal anecdotes are allowed as responses to this comment. Any anecdotal comments elsewhere in the discussion will be removed and our normal comment rules apply to all other comments.

A team of researchers from the Keck School of Medicine of USC found that exposure to a mixture of synthetic chemicals found widely in the environment alters several critical biological processes, including the metabolism of fats and amino acids, in both children and young adults. The disruption of these biological processes is connected to an increased risk of a very broad range of diseases, including developmental disorders, cardiovascular disease, metabolic disease and many types of cancer.
Known as per- and polyfluoroalkyl substances, or PFAS, these man-made chemicals are used in a wide range of consumer and industrial products. PFAS are sometimes called “forever chemicals” because they break down very slowly and accumulate in the environment and human tissue.
Although individual PFAS are known to increase the risk of several types of disease, this study, published February 22 in Environmental Health Perspectives, is the first to evaluate which biological processes are altered by exposure to a combination of multiple PFAS, which is important because most people carry a mixture of the chemicals in their blood.
“Our findings were surprising and have broad implications for policy makers trying to mitigate risk,” said Jesse A. Goodrich, PhD, assistant professor of population and public health sciences and lead author of the study. “We found that exposure to a combination of PFAS not only disrupted lipid and amino acid metabolism but also altered thyroid hormone function.”

This study shows association, not causation.
Also their participant group is specifically overweight/obese young adults. Would be interesting to see obesity vs. PFAS blood concentrations, since processed food packaging seems to contain PFAS.
