Non-caloric sweeteners in women of reproductive age – A consensus document

Non-nutritive sweeteners (NNS) are food additives that have been used as a possible tool to reduce energy and sugar intake. There is a scientific debate around the real benefits of their use. NNS are substances widely evaluated in the scientific literature. Their safety is reviewed by international regulatory health agencies. Health professionals and consumers often lack education and objective information about food additives based on the best scientific evidence. NNS have been used as a substitute for sucrose, especially by people with diabetes mellitus and obesity. However, concerns related to their possible association with preterm birth have been raised, and also with their use during pregnancy and lactation because of the possibility of metabolic or other consequences in both the mother and offspring. This analysis of the evidence in gynecology and obstetrics presents a review of the most commonly asked questions regarding this matter by health professionals and their patients. This document evaluates a diversity of scientific publications under the sieve of evidence-based medicine and the regulatory framework for food additives to elucidate whether the use of NNS in women in these critical stages of pregnancy and breastfeeding represents a potential risk.
