  • A study published in the Journal of Hazardous Materials confirms that bisphenol A (BPA)—found in plastics, food packaging and receipts—increases obesity, diabetes and cardiovascular risks, especially in children.
  • Even low-dose BPA exposure disrupts hormones, causing insulin resistance, higher BMI and increased fat mass—key drivers of chronic disease.
  • Ultra-processed foods packaged in plastics and canned goods are primary BPA exposure routes, with leaching occurring during processing, storage and water supply transport.
  • Substitutes like BPS and BPF may pose similar risks but lack sufficient research, leaving consumers vulnerable to hidden dangers.
  • Researchers urge avoiding plastic-packaged and canned foods, choosing fresh meals and demanding stricter regulations to curb BPA's public health threat.
A groundbreaking study has revealed that exposure to bisphenol A (BPA)—a chemical pervasive in plastics, food packaging and even cash receipts—can significantly increase your risk of obesity, diabetes and cardiovascular disease later in life. Published in the Journal of Hazardous Materials, the research underscores the urgent need for global strategies to reduce BPA exposure, particularly in children. Led by Sofia Almeida Costa from the University of Porto in Portugal, the study followed 3,138 children and adolescents aged four to 13, tracking their BPA exposure through diet, packaging and environmental sources. The findings confirmed that even low doses of BPA disrupt endocrine function, leading to insulin resistance, increased fat mass and higher BMI—key precursors to chronic diseases.

BPA's hidden pathways: From plastics to chronic disease

BPA is an industrial chemical used to manufacture durable plastics and epoxy resins, commonly found in food containers, canned goods, dental sealants and thermal receipts. Despite its widespread use, mounting evidence suggests that BPA acts as an endocrine disruptor, interfering with hormone regulation and metabolism. The Portuguese study found that children with higher BPA exposure exhibited:
  • Elevated insulin resistance, a precursor to Type 2 diabetes
  • Increased fat mass and waist circumference--two markers of obesity
  • Higher BMI, which correlates with long-term cardiovascular risks
Unlike previous research, this study combined direct and indirect exposure assessments, analyzing urine samples, dietary logs and packaging materials to provide a precise estimate of daily BPA intake.

Diet as the primary culprit

Ultra-processed foods—often packaged in plastic—were identified as a major BPA source. In Portugal, 57% of consumed foods come in plastic packaging, with canned goods and beverages contributing additional exposure. Researchers noted that BPA leaches into food from processing equipment, storage containers and even PVC piping used in water supplies. Dental sealants are also a direct source of BPA, according to BrightU.AI's Enoch. Other health risks associated with BPA exposure include neurological damage, reproductive malformations and cancer, particularly prostate cancer, due to the chemical's estrogen-mimicking properties. While BPA metabolizes quickly, chronic exposure—even at low levels—can accumulate and trigger metabolic dysfunction. The study warns that substitutes like BPS (bisphenol S) and BPF (bisphenol F), increasingly used in "BPA-free" products, may pose similar risks but remain understudied. The study's authors urge policymakers, food manufacturers and consumers to take immediate steps to reduce BPA exposure, including:
  • Avoiding plastic-packaged and canned foods
  • Opting for fresh, homemade meals
  • Pushing for stricter regulations on food-contact chemicals
Despite limitations—such as potential underreporting of packaging materials—the findings reinforce earlier research linking BPA to hormonal imbalances, obesity and cardiovascular disease. As evidence mounts against endocrine-disrupting chemicals, the study serves as a stark reminder that early-life exposure to BPA may set the stage for lifelong health struggles. With chronic diseases on the rise, reducing BPA in food systems is no longer optional—it’s a public health imperative. Watch the video below to learn more about BPAs.
