A week-long dietary and personal-care product intervention reduced the levels of plastic-associated chemicals in urine by about 60 percent [1].
This finding suggests that individuals can rapidly lower their exposure to synthetic chemicals linked to health concerns through simple behavioral shifts. Because these substances are pervasive in modern consumer goods, the ability to reduce their bodily presence in such a short timeframe provides a potential pathway for reducing long-term health risks.
Dr. Trisha Pasricha, a physician at Beth Israel Deaconess Medical Center and assistant professor of medicine at Harvard Medical School, said the results of the study [1, 2]. The research focused on whether modifying daily habits regarding diet and the use of personal-care products could impact the concentration of plastic-related chemicals in the body [2].
The intervention required participants to follow a low-plastic regimen for seven days [1, 3]. This involved changing the types of food consumed, and the personal-care products applied to the skin. By avoiding specific plastic-associated triggers, the study observed a sharp decline in chemical markers found in urinary samples [1].
While the specific list of excluded products was not detailed in the summary, the overall goal was to test the efficacy of reducing external exposure [2]. The results showed that the body can clear these chemicals quickly once the source of exposure is removed [1].
Pasricha said the study demonstrates that simple habits can lead to a significant reduction in the chemical burden on the body [3]. The 60 percent drop occurred within only one week of the intervention [1].

The study highlights the high bioavailability of plastic-associated chemicals and the speed at which the human body can eliminate them when exposure is curtailed. This suggests that the presence of these chemicals is largely dependent on continuous daily intake rather than permanent accumulation, meaning targeted consumer choices can have an immediate impact on internal chemical levels.
