Nutrition in pregnancy

Research on nutrition in pregnancy looks at what women eat, which nutrients matter, how weight changes across pregnancy, and what supplements may add. Reviews examine dietary patterns and nutrient intake in pregnancy and lactation, and link maternal diet to outcomes for the baby, including microbiota and developmental programming. One systematic review asks how maternal dietary patterns relate to postpartum depression.

Supplements are a frequent topic. Reviews ask whether micronutrient supplementation is still necessary in pregnancy, and a meta-analysis looks at supplements and pregnancy outcomes in women who are overweight or obese. An individual participant data meta-analysis examines balanced energy and protein supplementation and gestational weight gain in low- and middle-income countries. Other papers consider how nutrition evaluation fits into prenatal care and neonatal practice.

Parents often ask what to eat, whether they need supplements, and how much weight gain to expect. An educator may want slides that describe what the research covers, and that make clear individual questions belong with the prenatal care provider. The papers below are the ones the Hub tracks on this topic.
