Can swapping plastic stuff for non-plastic stuff clean your body of chemicals?
Low-plastic diet and urinary levels of plastic-associated phthalates and bisphenols: the randomized controlled PERTH Trial

Scientists gave people food, soap, and kitchen tools that didn't touch plastic for a week to see if it made chemicals in their pee go down.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Switching to food packaged in materials with less plastic led to measurable decreases in two specific phthalate chemicals in the urine of healthy adults after seven days, suggesting that food packaging is a major source of exposure to these substances.
People who eat canned foods have higher levels of bisphenol A in their urine, and switching to non-canned, low-plastic foods for a week reduces those levels by nearly 60%. This suggests that the lining inside metal cans contributes significantly to bisphenol A exposure.
Even when people reduced their intake of plastic in food and drinks, levels of a chemical called DEHP in their urine went up. This suggests that DEHP is entering the body through other sources like dust, air, or everyday products not related to diet.
When plastic containers are heated or scratched, chemicals called bisphenol A and phthalates can transfer into food and drinks. These same chemicals can be found unchanged in human urine after consumption.
Replacing everyday items like food containers, cookware, and personal care products with low-plastic versions for seven days led to measurable decreases in the levels of certain chemical compounds linked to endocrine disruption in the urine of healthy adults in Australia.
