Researchers in Chicago found an association between higher levels of PFOA and incidence of cardiovascular disease. The chemical, used in products such as polishes, paper and food packaging, is detectable in the blood of more than 98 percent of the US population.
One limitation to the study is that researchers relied on self-reported data about people’s diagnosis with CVD.
Professor Peter Weissberg, Medical Director at the British Heart Foundation (BHF), said: “This observational study showed that people with cardiovascular disease tend to have high levels of PFOA in their blood. This does not mean PFOA causes heart disease.
“We would need to see further research to properly establish whether this is a chance association or if PFOA does carry risks.
“In the meantime, the best way to avoid heart disease is to quit smoking, exercise regularly and eat a balanced diet. The type of food you eat will have a much greater influence on your heart health than the packaging it comes in.”
