Scientists in Australia are kicking off an exciting new trial to see if cutting out plastics can help improve health. This study, called the Plastic Exposure Reduction Transforms Health (PERTH) trial, will explore how a low-plastic diet and lifestyle might affect our bodies, especially concerning heart and metabolic health.
The PERTH trial is a big deal. It will involve 60 adults in Perth who have higher risks for cardiometabolic issues, such as obesity. Researchers will provide these participants with food and personal products that are completely free of plastics for four weeks. They’ll be looking closely at whether this leads to lower levels of plastic-related chemicals in their bodies.
What Are the Risks?
Many everyday plastics contain harmful chemicals called bisphenols and phthalates. These substances can disrupt hormones and are linked to various health problems, including obesity and diabetes. Research suggests that reducing exposure to these chemicals could significantly lower the risk of developing such conditions.
About the Study
Participants in the trial will be divided into two groups: one will follow the low-plastic intervention, while the other will continue with their usual lifestyle. The researchers will collect samples from the participants to monitor chemical levels in their bodies, as well as other health markers like blood pressure and body composition.
The study will likely use a questionnaire to track how participants come into contact with plastics. This thorough method aims to yield trustworthy results, as understanding all potential exposure routes is crucial for drawing accurate conclusions.
Why This Matters
Recent pilot studies show that over 90% of urine samples in healthy adults contained detectable levels of BPA, pointing to widespread plastic exposure in Australia. Previous shorter trials indicated that even a week of a low-plastic lifestyle could significantly reduce these harmful chemicals.
The PERTH trial could pave the way for new public health guidelines and better regulations on the use of such harmful substances in everyday products.
Looking Ahead
As we learn more about how reducing plastic can affect our health, this trial might show practical ways to empower individuals to make healthier choices. It’s a significant step from mere observation to real action against harmful chemicals in our lives.

This research could change the narrative around plastics and health, moving us closer to a safer and healthier future.
