Milk vs. water: surprising findings on Kids' hydration and brainpower
NCT ID NCT06711926
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This completed study tested how three different drinks—water, semi-skimmed milk, and whey permeate—affect hydration, thinking skills, and mood in 13 healthy children aged 9 to 11. Each child tried all three drinks on separate mornings, and researchers measured urine output, blood and breath samples, and cognitive performance. The goal was to find which drink keeps kids hydrated best and whether that helps them learn and feel better in school.
