I think it's the fact that when water evaporates it takes energy with it, keeping your food from heating past the boiling point of water. The water in food that you cook evaporates at a lower temperature at higher altitudes and prevents the food from being brought up to as high of a temperature as it would have if it were at a low altitude.
