Diet soda sweeteners found in breast milk – what does that mean for babies?
NCT ID NCT05379270
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether two common low-calorie sweeteners (sucralose and acesulfame-potassium) from diet soda pass into breast milk and then into a baby's blood. 82 breastfeeding mothers drank one diet soda, and researchers measured sweetener levels in their milk and blood over 72 hours, plus one sample from each baby. The goal was to see if these sweeteners actually reach infants, which would help design future studies on possible health effects.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
diet soda containing sucralose and acesulfame-potassium
What this could lead to
If it shows these sweeteners do pass into breast milk, it could lead to larger studies on whether early exposure affects infant health.
What could go wrong
This is a small, short-term study that only measures levels, not health effects. It cannot tell us if any exposure is harmful or safe.
