Milk is made up of 87% water and 13% solids. These solids include various fats and proteins. A protein called casein makes up about 80% of the whole protein content in the milk.

And since casein and most of the other proteins present are suspended uniformly throughout the milk, they scatter and deflect light uniformly through the visual spectrum resulting in the white colour.

So the next time someone asks why milk is white, tell them this.
