A large international study links a common plastic additive, DEHP, to hundreds of thousands of heart disease deaths worldwide in a single year. The research identifies DEHP, a primary plasticizer used to make plastics flexible, as a significant contributor to cardiovascular death. This finding is particularly relevant for Thailand, where plastic use is high in everyday life.
In Thailand, people regularly encounter phthalates through food packaging, cosmetics, cleaning products, and children’s toys. With heart disease already a leading health concern in the country, understanding environmental risk factors is crucial for families and health officials alike. Thailand’s health data show heart disease remains a major cause of mortality, underscoring the need to scrutinize exposure sources and protective measures.
The study, published in a peer‑reviewed journal, analyzed DEHP exposure data and mortality statistics from more than 200 countries, focusing on adults aged 55 to 64. Researchers estimate that DEHP exposure contributed to about 356,000 deaths worldwide in 2018 within this age group, representing a substantial share of global heart disease deaths. The heaviest burden appears in Africa, followed by East Asia and the Middle East, highlighting the widespread reach of this chemical in consumer products.
Phthalates, including DEHP, are used to soften plastics in items such as PVC pipes, medical devices, rain gear, fragrances, and food packaging. Humans are exposed through ingestion, inhalation, and skin contact—via microwaved meals, indoor air, or handling plastic products. Public health authorities note that everyday habits can raise exposure risks, and guidance emphasizes reducing contact with plastics when possible and choosing safer packaging alternatives.
Experts suggest that phthalates trigger cardiovascular inflammation and may accelerate the development of atherosclerosis, potentially increasing the risk of heart events. Some researchers also point to endocrine disruption linked to phthalate exposure, including lowered testosterone in men, which has been associated with cardiovascular risk in some studies. While these findings are concerning, researchers caution that more regional data are needed to tailor public health responses.
In Thailand, authorities have long promoted plastic reduction and better waste management, but gaps remain in monitoring exposure to plastic additives. The Ministry of Public Health and environmental agencies are calling for stronger surveillance, clearer labeling, and stricter controls on plastic components. Public health groups advocate for updated product safety standards and greater consumer awareness about reducing exposure.
Regulatory action around DEHP varies globally. In many Western countries, bans or restrictions cover children’s toys, cosmetics, and certain food packaging. Thailand is moving toward similar safeguards, but enforcement remains challenging amid growing plastic production and consumption. Experts emphasize practical steps that individuals can take today to minimize exposure.
Beyond heart health, phthalates have been studied for effects on reproduction, asthma, childhood obesity, and other health outcomes. While evidence strengthens the concern, researchers stress the importance of comprehensive public health strategies, including regulation, safer product design, and population monitoring.
Thai households can implement several simple precautions: avoid microwaving food in plastic containers, prefer unscented products, and store foods in glass, stainless steel, ceramic, or natural materials. Where possible, reduce consumption of heavily processed or canned foods. Parents should examine children’s toys for safety labeling and avoid products that are not clearly free of plasticizers. These steps, combined with broader regulatory action, can help reduce exposure.
The broader takeaway is clear: everyday plastics have real health implications. For Thailand’s fight against non-communicable diseases, reducing unnecessary plastic exposure and pushing for safer packaging can contribute to healthier communities. With coordinated action from health authorities, industry, and consumers, Thailand can address this global concern while retaining the benefits of modern living.
