It probably has something to do with the finite supply of drinking water on board, which has to be shared among everyone. Okay, some people actually do need more than others to be comfortable... but can you imagine if half the passengers turned into EWs about it?
The reason why packets are difficult to open is not because the "tube" is pressurised, but because it's still at a lower pressure than sea level - typically the equivalent of 8000 feet altitude, I believe. (I know, from brief experience on Sandia peak, that vigourous exercise above that altitude will get you out of breath very quickly.) The packet was probably packed at sea level pressure, or nearly so. I wonder if "airline peanuts" packets are specially packed for opening at 8000 feet equivalent pressure?
The restriction against hot food is probably because the official meals come in trays, which are probably type-approved to avoid accidentally spilling the contents in awkward places. Sort-of like McDonalds coffee being too hot if mishandled, if you see what I mean.
