Seven-Day Low-Plastic Intervention Lowers Urinary Phthalates and Bisphenol A

Ubiquitous environmental exposure to endocrine-disrupting chemicals, particularly plasticizers like phthalates and bisphenols, has emerged as a significant contributor to the global burden of chronic disease [1]. These compounds interfere with homeostatic control and have been linked to increased carotid intima-media thickness (a measure of the inner layers of the carotid artery used to detect early-stage atherosclerosis), subclinical atherosclerosis, and hypertensive disorders during pregnancy [2, 3]. Beyond vascular damage, high urinary concentrations of these chemicals are associated with a greater prevalence of type 2 diabetes, obesity, and systemic oxidative stress [4, 5]. While the molecular mechanisms involve complex perturbations of peroxisome proliferator-activated receptor gamma (a nuclear receptor protein that regulates fatty acid storage and glucose metabolism) and liver gene networks, the clinical challenge remains identifying effective methods for reducing a patient's internal chemical load [6]. A new randomized controlled trial now evaluates whether specific dietary and lifestyle modifications can rapidly decrease these systemic biomarkers.
