Answer 1

Because temperature fluctuates & a sunny day can easily spoil everything in the fridge, while extra cold days & nights would cause things that you don’t want frozen to a hard block of ice, like eggs or juice or, really, anything you intend to consume regularly in a non-solidified form.

Basically, temperature control means food that spoils more “predictably” & is in the state of matter required for most efficient consumption.
