It’s not all in your head — those food crav­ings you’ve been hav­ing might be pan­demic re­lated. And whether you’re jonesing for pick­les or potato chips, there’s science to back up your yen.

Crav­ings in­volve many parts of the brain, in­clud­ing the mas­ter stress neu­ro­trans­mit­ter CRF (cor­ti­cotropin re­leas­ing fac­tor), which is likely very ac­tive dur­ing a global health cri­sis.

“CRF can di­rectly pro­mote craving it­self,” Kent Ber­ridge, a pro­fes­sor of psychology and neu­ro­science at the Univer­sity of Michi­gan, tells Del­ish.

Al­though neu­ro­science can’t ex­plain the tar­get of our crav­ings (for ex­am­ple why Grape Crush and not Or­ange Fanta), Ber­ridge says they aren’t ran­dom: “They’re spe­cific to you as an in­di­vid­ual, and your his­tory with foods, and your par­tic­u­lar likes and dis­likes.”
