Litvak J, et al. - Researchers conducted this systematic review to explore the connection between prenatal dietary exposures (eg, dietary patterns, foods and macronutrients, and beverages) and offspring body size between 6 months and 18 years. Using the PRISMA guidelines, articles were identified in PubMed and Web of Science (January 2010-March 2018). Through a reference review of articles that met the inclusion criteria and related reviews, additional studies were identified. In total, 851 research articles have been assessed. Adhering to a Mediterranean diet and restricting refined carbohydrates during pregnancy that affect the body size of offspring from 6 months to 18 years. There was no correlation between data-driven dietary patterns and offspring body size, and a pro-inflammatory diet pattern and offspring body size. Mixed and null results have been found for the association between total carbohydrates, n-3 polyunsaturated fatty acids, protein, sugar-sweetened beverages, and artificially sweetened beverages and body size of offspring. The divergent results between the studies underline the difficulty of this topic.
