Comparison of the Effects of Plastic-Free Diet, Plastic-Free Diet Education and Exposure Feedback on Urinary Bisphenol: A Levels in Adolescents.
Fatma Ulusoy, Sebahat Gözüm, Mesut Parlak
PMID 40448346WHAT IT FOUND
The approaches did not differ, but plastic-free diet, plastic-free diet education, and BPA exposure feedback all lowered adolescents' urinary BPA from pre-test to post-test.
Key findings
01Urinary BPA/creatinine values decreased from pre-test to post-test across the intervention groups.
02The intervention groups did not differ significantly in post-test urinary BPA levels.
03Post-test urinary BPA/creatinine values were 1.51 ± 0.63, 1.47 ± 0.69, and 1.66 ± 0.66 μg/g creatinine.

What it does not show
The intervention groups were not randomized, so baseline differences or selection could have influenced the results. Participants were female adolescents from two high schools, so the findings may not apply to boys, other ages, or other settings. The study measured urinary BPA only, not long-term health effects. Plastic-packaged product use was self-reported, and actual eating behavior could not be fully controlled. All participants received urinary BPA feedback, so the study cannot isolate the effect of feedback from the other components.
Declared interests
The authors declared no potential conflicts of interest. The study was funded by Akdeniz University Scientific Research Projects Coordination Unit, project number TDK-2023-6702, and was based on the first author's PhD thesis.
The easy way to misread this
Do not conclude that the plastic-free diet is better than education or feedback. The between-group post-test comparison was not significant (p = 0.414), and the significant decrease was within groups from pre-test to post-test.
