Association of diet with per- and polyfluoroalkyl substances in plasma and human milk in the New Hampshire Birth Cohort Study
Science
11 May 2024 | Sci Total Environ
Certain dietary factors during pregnancy, such as increased consumption of fish/seafood, eggs, coffee, or white rice, were found to be associated with higher concentrations of PFAS in both maternal plasma and human milk, indicating the importance of understanding food-related sources of PFAS exposure for pregnant individuals and their offspring. Fruit, whole grain, and fiber consumption was associated with lower levels of PFAS in maternal plasma.
