Diet soda chemicals found in breast milk – what does that mean for babies?

This study looked at whether two common low-calorie sweeteners (sucralose and acesulfame-potassium) pass from a mother's diet into her breast milk and then into her baby's blood. 82 breastfeeding mothers drank a diet beverage, and researchers measured sweetener levels in their milk and blood over 72 hours, plus a single sample from their infants. The goal was to gather data to design larger studies on the health effects of early-life exposure to these sweeteners.
