Althought plant-based diets are at risk of nutritional deficiencies such as proteins, iron, vitamin D, calcium, iodine, omega-3, and vitamin B12, the available evidence shows that well planned vegetarian and vegan diets may be considered safe during pregnancy and lactation, but they require a strong awareness for a balanced intake of key nutrients. A review of the scientific literature in this field was performed, focusing specifically on observational studies in humans, in order to investigate protective effects elicited by maternal diets enriched in plant-derived foods and possible unfavorable outcomes related to micronutrients deficiencies and their impact on fetal development. A design of pregestational nutrition intervention is required in order to avoid maternal undernutrition and consequent impaired fetal growth.29 p.application/pdfengcc-by (c) Sebastiani, Giorgia et al., 2019http://creativecommons.org/licenses/by/3.0/esVegetarianismeVeganismeEmbarassadesAlletamentOligoelements en la nutricióVegetarianismVeganismPregnant womenBreastfeedingTrace elements in nutritioninfo:eu-repo/semantics/article6895292020-05-06info:eu-repo/semantics/openAccess30845641
