Why do most foods taste better when they are hot?

The occasional cold pizza can be delicious but for the most part humans generally eat their food hot.  Why?

A huge percentage of "taste" actually occurs through the olfactory receptors (smell). Particles move more quickly when that are hot and can be more easily received by the nose.  We are able to detect more flavor when food is hot.  This is why icecream tastes sweeter the more it melts, our nose can start picking up more of the particles. You can test this in a weird way by taking a jelly bean or a cheeto or something and holding your nose closed, putting the food in your mouth and chewing it. You can only taste certain parts of it (ie the sweetness or the saltiness) but halfway through chewing unplug your nose and you will be able to "taste" its flavor.
