New study reveals that exposure to a group of widely used ‘forever chemicals’ may increase diabetes risk in middle-aged women

A new study published in Diabetologia found that exposure to per- and polyfluoroalkyl substances (PFAS) is associated with an increased risk of developing diabetes in midlife women. The study analyzed the stored blood and urine samples from 1400 participants and found a stronger association with combined exposure to multiple PFAS.
