APrON study suggests pregnant & lactating women not meeting recommended intake
Alberta Pregnancy Outcomes and Nutrition (APrON) is a birth cohort involving over two thousand women and their infants from Calgary and Edmonton.
The main objective of APrON is to understand the relationship between maternal nutrient status during pregnancy and maternal mental health and child health and development.
As part of the project, the APrON team studied the first 600 women in the cohort during and after their pregnancy to see whether they were consuming enough omega-3 long chain polyunsaturated fatty acids (omega 3-LCPUFA) to meet current recommendations.
Omega-3 LCPUFA include eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA) and docosahexaenoic acid (DHA). A source of these is required during pregnancy for fetal and placental development and is critical for the development of the infant, particularly for brain development.
The American Dietetic Association along with Dietitians of Canada recommends that all healthy adults including pregnant and lactating women consume at least 500 mg/day of omega-3 LCPUFA. The European Commission and the International Society for the Study of Fatty Acids and Lipids (ISSFAL) specifically recommends that pregnant and lactating women consume a minimum of 200 mg DHA per day.
According to the study: "Only 27% of women during pregnancy and 25% at three months postpartum met the current European Union (EU) consensus recommendation for DHA. Seafood, fish and seaweed products contributed to 79% of overall n-3 long chain polyunsaturated fatty acids intake from foods, with the majority from salmon. Results suggest that the majority of women in the cohort were not meeting the EU recommendation for DHA during pregnancy and lactation."
The current study found women who took a supplement containing DHA were 10.6 and 11.1 times more likely to meet the current EU consensus recommendation for pregnancy and postpartum, respectively. Recommendations could also be met by following the Health Canada recommendation to consume one to two portions per week of fish high in omega-3 fatty acids.
