The honest verdict

Is Diet Coke Actually Healthy?

Honestly? The zero-calorie label is real, and the evidence against aspartame at normal intakes is weaker than the internet suggests. The fair criticisms are softer ones: it keeps your palate trained to intense sweetness, and some people find it triggers cravings. If you want off artificial sweeteners without giving up the fizzy cola ritual, there are gentler places to land.
