In our cover story for the latest Medicus, an internationally lauded clinical trial by researchers at The University of Western Australia has shown there are quick and effective ways in daily life to reduce the levels of harmful plastic-associated chemicals in our bodies. But some unexpected results of the study were not so positive.
The research team developed a world-first 24-hour survey tool that collected data from the cohort to investigate associations between PACs and diet and lifestyle behaviours, body composition and blood biomarkers.
“That behaviour analysis, in conjunction with measuring the plastic exposure of people in their urine, particularly the plastic-associated chemicals, allowed us to understand where the high exposures from plastic come from in our everyday lifestyle,” Prof Lucas says.
“We identified that food was a major source, particularly if you consume a lot of ultra-processed, highly processed food. Another example was the lining of tins that came up as a contributor to the level of bisphenols in your body.
RESEARCH FACTS
🥤 Test results from the initial PERTH Trial cohort showed that all participants were excreting at least six plastic-related metabolites on any given day.
🥤 In the randomised controlled clinical trial, the maximum intervention resulted in phthalates decreasing by more than 44% and bisphenols by more than 50%.
🥤 The trial showed that a lean person will excrete a lot more of these chemicals within a 24-hour period than a person who is obese.
