[Non-caloric sweeteners in pregnancy and lactation].

Many pregnancies have a weight gain that is higher than recommended, situation that carries several risks for the mother and her child. As a strategy to achieve a lower weight gain, the replacement of sugar-sweetened foods and beverages by those with non-caloric sweeteners could be a choice for pregnant or puerperal mothers. The objective of this article is to review the available evidence regarding the use of non-caloric sweeteners during pregnancy and lactation. Pregnancy is not a period to lose weight, so it would not be advisable to perform hypocaloric diets. However, to achieve an adequate weight gain during pregnancy, many women choose to consume food and beverages with non-caloric sweeteners. During pregnancy, the consumption of cyclamate, saccharin and crude stevia leaf should be avoided, as well as that of stevia infusions or extracts of the whole leaf. Regarding the rest of the approved non-caloric sweeteners, their consumption during pregnancy and lactation is considered to be safe, as long as they are consumed in moderation, adhering to their admissible daily intake levels. Aspartame does not reach breast milk. While saccharin, sucralose, and acesulfame-K are detectable in breast milk, their concentration is several orders of magnitude below their admissible daily intake levels.
