Ultra-processed food intake can increase human exposure to phthalates and microplastics

Two studies analyzed ultra-processed foods for phthalates and microplastics; report that consumption of ultra-processed foods and fast food during pregnancy increases exposure to phthalates; link lower socioeconomic status to increased ultra-processed food consumption and phthalate exposure; find highly-processed protein products in the US to contain significantly more microplastics than minimally-processed products; hypothesize plastic processing equipment to be one main source
