Acesulfame has been found in variable concentrations in the breastmilk of nursing mothers who report consuming artificially sweetened beverages and sweetener packets in the past 24 hours. Even some mothers who reported not consuming artificial sweeteners have small amounts of acesulfame in their breastmilk. However, it is not likely to reach an intake greater than the acceptable daily intake for infants.[1] Ingestion of diet drinks containing low-calorie sweeteners might increase the risk of vomiting in breastfed infants. Some authors suggest that women may wish to limit the consumption of nonnutritive sweeteners while breastfeeding because their effect on the nursing infants are unknown.[2,3]
