A recent study highlighted in the journal Acta Obstetricia et Gynecologica Scandinavica has sparked discussions about the impact of diet on pregnancy outcomes, particularly for women following vegan diets.
This research involved a large group of women, totaling 65,872, who were categorized based on their dietary preferences: omnivores, fish/poultry vegetarians, lacto/ovo vegetarians, and vegans.
The study aimed to explore how these dietary choices affect pregnancy, focusing on protein and micronutrient intake, the risk of developing preeclampsia—a serious pregnancy complication marked by high blood pressure—and the birth weight of newborns.
The findings showed that vegan mothers and those who consume lacto/ovo vegetarian diets tend to have lower protein intake compared to their omnivorous counterparts, with vegans reporting the lowest protein consumption at 10.4%, followed by lacto/ovo vegetarians at 13.3%, and omnivores at 15.4%.
In terms of micronutrient intake, vegans were found to have much lower levels compared to other groups.
However, when dietary supplements were taken into account, these differences were not as pronounced, suggesting that supplements could help bridge the nutritional gap for those on plant-based diets.
One of the more concerning findings of the study was the higher prevalence of preeclampsia among vegan mothers compared to those who eat a varied diet including meat.
Additionally, the study noted that newborns of vegan mothers tended to weigh less by an average of 240 grams than those born to omnivorous mothers.
These findings underscore the need for further research to understand the potential causality between plant-based diets and pregnancy outcomes better.
Such research could provide a stronger foundation for dietary recommendations for pregnant women, ensuring both the mother’s and the baby’s health and well-being.
The study’s authors call for more in-depth investigations to confirm these initial observations and to help guide expectant mothers in making informed dietary choices that support optimal pregnancy outcomes.
