The consumption of canned food and beverages and urinary Bisphenol A concentrations in NHANES 2003–2008

Abstract

Background Exposure to Bisphenol A (BPA) is ubiquitous and includes dietary and environmental pathways. BPA is rapidly glucuronidated in the body, and both BPA and its conjugates can be readily measured in urine. Objectives To investigate the contribution of canned food and beverages, known sources of BPA contamination, to BPA biomarkers of exposure using dietary and urinary BPA concentration information in a representative sample of the U.S. population. Methods We evaluated 7,669 NHANES 2003–2008 participants 6 years and older with 24-hour dietary recall information and urinary BPA concentrations available. Using linear regression models, we evaluated the associations between recent canned food and beverage consumption and urinary BPA concentrations, adjusting for potential confounders. Results We found 9% of our participants consumed one canned food in the past 24 hours and 2% consumed two or more canned foods. The consumption of one canned food vs. none was associated with 24% (95% CI 1.11, 1.38) higher urinary BPA concentrations. The consumption of two or more canned foods vs. none was associated with 54% (95% CI 1.27, 1.88) higher urinary BPA concentrations. The consumption of one or more of some specific types of canned foods vs. none were associated with higher urinary BPA concentrations: 41% (95% CI 1.23, 1.63) higher BPA for vegetable and fruit, 70% (95% CI 1.18, 2.44) higher for canned pasta, and 229% (95% CI 1.22, 4.30) higher for canned soup. Canned beverages were not associated with urinary BPA concentrations. Conclusions Canned food, including some specific types such as canned vegetable and fruit, canned pasta, and canned soup were associated with higher levels of urinary BPA concentrations.

Are Canned Beverages Industries Progressively Switching to Bisphenol AF?

“…Recent studies highlighted the existence of a relationship between environmental exposure to EDCs and the development of endocrine system-related diseases, even if the detailed pathologic pathway of such disorders has not been completely unraveled yet (De Coster & van Larebeke, 2012). Bisphenol A (BPA), a synthetic xenoestrogen acting as EDC, was approved for use in food packaging in the 1960s (Hartle, Navas-Acien, & Lawrence, 2016). BPA is the monomer of the enamel coating of epoxy resins used to line the inside of many food and beverage containers (Hartle et al, 2016).…”

BPA is the monomer of the enamel coating of epoxy resins used to line the inside of many food and beverage containers (Hartle et al, 2016). It is also found in products used on a daily basis, such as plastic bottles, flame retardants, toys, cosmetics, and thermal paper (G. Russo, Barbato, & Grumetto, 2017).…”

Influence of a storage conditions on migration of bisphenol A from epoxy-phenolic coating to canned meat products

“…[8][9][10][11][12][13][14][15][16][17] In addition, there has been recently reported a marked increase in urinary BPA levels in humans who consumed canned foodstuff. 18 Food packaged in tinplate cans coated with epoxy resins is generally considered to be the predominant "source" of exposure to BPA. 19,20 Because of that, France officially passed a law suspending the production, trade and marketing of food cans containing BPA in December, 2012.…”

Parental Concern about Environmental Chemical Exposures and Children's Urinary Concentrations of Phthalates and Phenols

“…BPA exposure occurs largely from dietary intake due to its use in food packaging materials, including the linings of food cans and plastic containers. Consuming canned soup and water from BPA-containing packaging and bottles can cause increases in urinary BPA concentrations (28-30). …”
