A global study has linked exposure to phthalates—chemicals found in everyday products like food containers, cosmetics, and plastics—to over 10% of heart disease deaths among people aged 55–64 in 2018. Researchers estimate that the phthalate DEHP alone may have contributed to nearly 370,000 deaths worldwide in that age group, raising alarms about the chemical’s impact on cardiovascular health.
Phthalates are known to cause systemic inflammation and disrupt testosterone levels, a key predictor of heart disease in men, according to Dr. Leonardo Trasande of NYU’s Grossman School of Medicine, the study’s senior author. While these chemicals are commonly used to make plastics more flexible, they’re also found in fragrances, vinyl flooring, and personal care products.

The study’s findings are consistent with existing concerns about phthalates’ broader health effects, which include reproductive harm, asthma, obesity, and certain cancers. Health advocates are now calling for stricter regulations and increased consumer awareness.
To limit exposure, experts recommend avoiding plastic food containers, especially when microwaving, choosing unscented products, and switching to glass or stainless steel for food storage. Regular handwashing and minimizing processed food intake are also advised.
