Nutritional Strategies to Delay or Reverse the Burden of Negative Obstetric Outcomes Related to Covid19 Exposure During Pregnancy: Recent Advances

Background: /Objectives: the SARS-CoV-2 (COVID-19) pandemic has significantly impacted a large portion of the global population. Numerous studies have investigated the potential outcomes of Coronavirus infection in pregnant women, aiming to identify variables that may be associated with either improved or worsened outcomes. In this context, nutritional factors have occasionally been hypothesized to play a potentially important role in preventing adverse obstetric outcomes in pregnant women affected by COVID-19. We conducted a comprehensive literature review to examine the relationship between COVID-19 and nutrition. Our objective was to provide an updated and state-of-the-art overview of the interactions between nutrition, COVID-19 infection during pregnancy, and perinatal, obstetric, and neonatal outcomes. Methods: we conducted a comprehensive literature search in electronic databases, namely PubMed, Medline, and Embase, focusing on the relationship between COVID-19 and the role of diet and micronutrients in pregnancy. Results: an adequate nutritional intake, coupled with a healthy lifestyle, along with the consumption of probiotics and prebiotics and the supplementation of specific micronutrients, appears to play a crucial role in preventing adverse outcomes and pregnancy complications associated with COVID-19. Conclusions: obstetric research must continue to advance preventive strategies against the SARS-CoV-2 virus, including those focused on nutrition.
