You are what you eat

Anyone who’s ever tried to cure the blues with Ben and Jerry’s knows that there is a link between our stomachs and our moods. Foods high in fat and sugar release pleasure chemicals like dopamine and opioids into our brains in much the same way that drugs do, and I’d certainly argue that french fries and a chocolate milkshake can perk up even the lousiest of days.

This brain-belly connection works in the opposite direction, too. Ever felt nauseous before giving a big presentation? Or had butterflies in your stomach on a first date? It’s this system relating feedback from your brain to your gut causing those sensations and giving you physical signals that something big is about to happen.
