The same brain circuits involved in drug and alcohol addiction are hijacked by ultra-processed foods, and dynorphins are the key players. These peptides attach to kappa opioid receptors, initially reducing dopamine and creating dysphoria that drives you to seek more food rewards. Scientific research shows that blocking these receptors reduces binge eating in animal studies, offering hope for new therapeutic approaches to food addiction.
