Microscopic plastic particles found in F&B may affect glucose metabolism and harm organs such as the liver, according to a new animal study. The findings, presented during the ongoing Nutrition 2025 conference (May 31–June 3), point to the need for more research. The researchers gave mice a daily dose of polystyrene nanoparticles (<100 nm) in addition to their standard rodent diet. Polystyrene is a commonly used plastic in food packaging and products.
