Preeclampsia is marked by a sudden increase in blood pressure, protein in the urine, or other problems during pregnancy, which can cause serious health problems for mothers and babies if left untreated. Researchers report that participants in the Nulliparous Pregnancy Outcomes Study who closely adhered to the Mediterranean diet—an eating pattern rich in fruits, vegetables, legumes, whole grains, fish, olive oil, and raw nuts—at the time of conception had a 28% lower risk for preeclampsia.
