The Take
Diet Pepsi is not healthy. It earns an 89 Slop Score as aspartame arc fuel that swaps real sugar for a double lab sweetener hit and tooth-eroding acid.
Status signalers chasing "diet" cred without calories end up coping with fake sugar ghosts and phosphoric acid that files enamel while delivering nothing but caffeine jitter.
The Verdict
Diet Pepsi markets itself as the smart cola choice but stacks two artificial sweeteners, caramel dye, and acid with zero redeeming nutrition. The identity play is virtue-signaling "I'm watching my weight" while ignoring the ultra-processed reality.
Skip it. Buy LMNT or plain sparkling water with lime — actual electrolytes, zero lab sweetener regret. Slop Score 89.
