Mediterranean Diet During Pregnancy

JAMA. 2019;322(12):1134. doi:10.1001/jama.2019.13918

Eating a Mediterranean-style diet during pregnancy did not result in fewer adverse maternal and offspring complications, but women gained less gestational weight and reduced their risk of gestational diabetes, according to a trial in PLOS Medicine.

The 1252 inner-city pregnant women with metabolic risk factors (obesity, chronic hypertension, or hypertriglyceridemia) were randomly assigned to a Mediterranean-style diet (supplemented with mixed nuts and olive oil) or to usual care. All participants received 3 individualized sessions of dietary advice. The composite primary outcome for mothers was gestational diabetes or preeclampsia and the composite offspring outcome was stillbirth, small for gestational age, or admission to neonatal care unit.
