A new study has found a significant link between high exposure to phthalate, chemicals commonly found in plastic, and increased risks of heart disease and early death.
Phthalates, often referred to as “everywhere chemicals,” are used to make plastics more durable and are present in hundreds of everyday products, including food packaging, personal care items, and medical devices. Researchers now warn that long-term exposure to these substances may be more dangerous to cardiovascular health than previously understood.
The research, published in the Journal of Clinical Endocrinology and Metabolism, analyzed data from over 5,000 adults in the United States. It revealed that people with the highest levels of phthalate exposure had up to a 50% greater risk of dying from cardiovascular disease compared to those with the lowest levels. The study also noted links to high blood pressure and inflammation, both key contributors to heart conditions.
“These findings add to growing evidence that phthalates may be harming our cardiovascular system and overall health,” said Dr. Leonardo Trasande, an environmental health expert and co-author of the study. “We need stronger regulatory action to limit exposure.”
Phthalates can enter the body through ingestion, inhalation, and skin contact. Previous studies have also associated them with hormone disruption, obesity, diabetes, and reproductive issues.
In response to the study, public health advocates are urging consumers to reduce use of plastic containers, especially when heating food, and to opt for phthalate-free personal care products.
The U.S. Environmental Protection Agency (EPA) is reviewing existing regulations, while the Food and Drug Administration (FDA) has maintained that current exposure levels are within safe limits—a position now under increasing scrutiny.
As researchers call for further studies to confirm the findings and better understand mechanisms involved, they also emphasize that small lifestyle changes could significantly reduce personal risk.
