Milk Could Be a More Effective Hydration Source Than Water

A TODAY health expert says milk (skim or whole) can outperform water in hydrating the body because its natural electrolytes, plus fat and protein, help retain fluids longer. Small studies suggest milk may keep people hydrated longer than water. For extra hydration, options include milk, water paired with a salty snack, coconut water, or a DIY electrolyte drink; people who sweat heavily, are ill, or take certain medications may benefit from electrolytes, though most can stay hydrated with regular water and meals.
