Food comas could actually serve a greater purpose.
New York University researchers looked at a specific type of slug and discovered after eating a lot of calories it went into a food coma, and its body distributed its energy into both storing nutrients and to memory.
Study senior author Thomas Carew adds,” […] it’s been widely established that in an array of animals, including humans, sleep is well known to be required for proper storage of long-term memories acquired during wakefulness.
Perhaps the drowsiness experienced after a meal is a similar way to preserve a memory about that meal, so as to come back to it in the future.”
