Milk may ward off diabetes in Lactose-Intolerant individuals
NCT ID NCT06513026
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether drinking regular milk can lower the risk of type 2 diabetes in people with lactose intolerance who also have pre-diabetes. Researchers will compare regular milk to lactose-free milk over 12 weeks in 40 adults. They will measure changes in gut bacteria, blood sugar levels, and digestive symptoms.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lactose-containing milk
- What this could lead to
- If it works, this could point toward a simple dietary approach to reduce type 2 diabetes risk in people with lactose intolerance.
- What could go wrong
- This is a very small, early-stage trial with only 40 participants. The results may not apply to everyone, and drinking milk could cause digestive discomfort.
