One-Carbon Metabolism Nutrient Intakes among Canadian Woman of Childbearing Years: Findings from the 2015 Canadian Community Health Survey – Nutrition 

Abstract

A large portion of Canadian WCBY are meeting current nutrient recommendations for folate, vitamin B 6 and vitamin B 12 .• While food sources for choline are primarily animal in origin, the majority of women are not meeting the AI for choline.• Given the importance of choline in pregnancy, strategies are needed to improve intake.• Adequate intake of one-carbon (1C) metabolism nutrients are vital for normal fetal development.• The key nutrients involved in 1C metabolism are folate, choline, vitamins B 6 and B 12.• While the importance of periconceptual folate intake has been well established as a public heath approach to neural tube defect (NTD) reduction, growing evidence suggests inadequate intakes of choline and vitamins B 6 and B 12 are also linked to NTD risk. 1,2 • Currently, limited research exists which examines 1C intakes among Canadian women of childbearing years (WCBY).
