Researchers Find Majority of Women Lack Essential Nutrients for Healthy Pregnancy
A recent study involving 1,729 women from the UK, Singapore, and New Zealand reveals that the majority of women are not receiving adequate essential nutrients crucial for a healthy pregnancy. The research highlights concerns that this nutritional inadequacy might escalate, particularly with the growing popularity of vegetarian and vegan diets.
The investigation focused on the vitamin levels, specifically those typically found in meat and dairy products, including vitamins D, B12, and B6, as well as folic acid and riboflavin. These nutrients play vital roles in preventing birth defects, promoting bone health, and supporting the overall development of the baby during pregnancy.
Alarming findings from the study indicate that over 90% of the women had insufficient concentrations of one or more of these essential vitamins, with a significant number exhibiting signs of B6 deficiency in late pregnancy. The lead author, Professor Keith Godfrey from the University of Southampton, expressed concern that the global shift towards reducing meat and dairy consumption for carbon emissions might exacerbate this nutritional shortfall, potentially impacting unborn children in the long term.
The research involved two groups of women, with both receiving supplements containing folic acid, iron, calcium, iodine, and beta-carotene. The control group, in addition to these, also received supplements with riboflavin, vitamin B6, vitamin B12, vitamin D, zinc, myo-inositol, and probiotics. Blood samples collected at various stages indicated that the supplemented group showed reduced deficiencies.
The study calls for a reevaluation of dietary recommendations for preconception and pregnancy, especially with the rising popularity of less nutrient-dense diets. It suggests considering the role of multiple micronutrient supplements, particularly for women in higher-income countries. Current NHS guidelines recommend daily folic acid intake for women planning pregnancy, emphasising the need for vitamin D supplementation. The researchers stress that nutrient deficiencies are not exclusive to underdeveloped nations but are increasingly prevalent among women in high-income countries. The findings were published in PLOS Medicine and involved collaboration from institutions including the University of Southampton, the University of Auckland, the National University of Singapore, and the Agency for Science, Research, and Technology in Singapore.
