ABSTRACT
Introduction:
Bisphenol A (BPA) is an organic endocrine disrupting chemical (EDC) that modifies the activity of hormones, leading to adverse health effects. BPA is a stabilizer of polyvinyl chloride – one of the most common synthetic plastic polymers, used in the production of common products, including packaging materials, plastic bottles, toys, and thermal paper; it is also used to synthetize the epoxy resins, a component of food cans. Hence, consumption of canned products – the source of BPA exposure – increases BPA concentration in human body and may increase the risk of several lifestyle diseases and hormonal, metabolic, and fertility disorders.
Objectives:
To evaluate the regularity of consumption of canned products among young women living in the city of Gdansk (Poland).
Patients and methods:
277 women filled a food frequency questionnaire to determine consumption of alimentary products which, according to published research, may be contaminated with BPA
Results:
Products with high BPA content (>100 ng/g) were consumed at least once a week by 7% of respondents, while these with moderate (10-100 ng/g) and low (<10 ng/g) content of BPA by 33% and 60%, respectively.
Conclusions:
Young women regularly consume canned products, mostly with low or moderate BPA content. However, persistent exposure, even at low doses, may trigger adverse health effects. Thus, it is crucial to conduct further research on the effects of this EDC on human health and reconsider tolerable daily intake, if such a safe dose of BPA exposure exists. Simultaneously, it would be advisable to find safer materials for food packaging, free from EDC.
