Researchers from the University of Copenhagen have observed that pregnant people who follow vegan diets may face a higher risk of preeclampsia and delivering a low birth weight baby. The findings were reported in the journal Acta Obstetricia and Gynecologica Scandinavica (AOGS).
In the study, more than 65,000 participants completed mid-pregnancy questionnaires detailing their dietary patterns. Health outcomes were tracked through delivery. The data showed that protein intake tended to be lower among vegetarians (13.3%) and vegans (10.4%), and several micronutrients were notably reduced among vegans who did not use dietary supplements.
The researchers found a greater occurrence of preeclampsia in these two groups, and the babies born to vegan and vegetarian participants weighed on average about 240 grams less at birth. When a newborn’s weight falls outside the normal range, it can raise the risk of respiratory issues, skin and organ infections, digestive problems, and potential neurological concerns later on.
The authors emphasized the need for additional research to determine whether a causal link exists between plant-based diets during pregnancy and birth outcomes. Such work would help refine dietary guidelines for expectant mothers and healthcare providers.
In related findings, earlier investigations have challenged myths about stevia and its effects on gut microbiota, suggesting that stevia may not pose the dietary risks previously assumed by some researchers.
