Elevated Maternal Folate Status and Changes in Maternal Prolactin, Placental Lactogen and Placental Growth Hormone Following Folic Acid Food Fortification: Evidence from Two Prospective Pregnancy Cohorts

Abstract: Folic acid (FA) food fortification in Australia has resulted in a higher-than-expected intake of FA during pregnancy. High FA intake is associated with increased insulin resistance and gestational diabetes. We aimed to establish whether maternal one-carbon metabolism and hormones that regulate glucose homeostasis change in healthy pregnancies post-FA food fortification. Circulating folate, B12, homocysteine, prolactin (PRL), human placental lactogen (hPL) and placental growth hormone (GH2) were measured in ear… Show more

“…Due to these differences, there are specific dietary recommendations and reference values for pregnant women. For example, the 2012 Nordic Nutrition Recommendations and the 2020-2025 Dietary Guidelines for Americans include specific recommendations for pregnant women (8)(9)(10)(11)(12).…”

“…However, the study did not observe any specific dose or duration-related associations between folic acid supplementation and the risk of GDM. Notably, two prospective pregnancy cohorts performed in Australia investigating the impact of folic acid fortification unveiled changes in hormonal profiles, raising concerns regarding the appropriateness of folic acid supplementation and the potential risks related to insulin resistance and gestational diabetes in specific populations [5]. These results highlight the complexities in understanding the relationship between folic acid supplementation and GDM risk.…”
