A recent study published in the European Journal of Nutrition led by Dr. Meghan Muse and Dr. Caitlin Howe found that during pregnancy, circulating levels of select miRNA may be altered by maternal diet quality, specifically the consumption of red and processed meat. These miRNAs are known to regulate genes involved in placental development. They may therefore shed light on possible mechanisms underlying the link between the consumption of red and processed meats and the risk of preeclampsia.
