A Week of Plastic-Free Eating Slashes Urinary Plastic Chemicals (Up to 60%)

A seven-day randomized trial in 60 Australians found that a diet and kitchenware with minimal plastic contact reduced urinary levels of plastic-associated chemicals, with the low-plastic food plus kitchenware group showing mono-n-butyl phthalate 38% lower, mono-benzyl phthalate 54% lower, and BPA 60% lower than controls; the broader study confirms pervasive exposure but long-term health effects remain unknown. The findings were published in Nature Medicine and suggest that reducing plastic contact from production to plate can lower body burdens within a week, though health implications require further study.
