They are usually known to eaten food suited for them. Snail-Po is a popular example of this. However, there have been occasions where they have consumed foods meant for humans; the alley snails from the episode "Have You Seen This Snail?" are shown to like nachos, and Gary is shown eating cookies in the same episode as well as "Dumped." He also eats a potato chip in "I Had an Accident." Also, in several episodes, it is suggested that Gary chews up the sofa in SpongeBob's living room whenever the latter is gone for long periods of time and not around to feed him.
