Diet Dr. Pepper vs. Dr. Pepper Original

High fructose corn syrup (rather than aspartame) as used as a sweetener.

All of the other ingredients are the same.

High fructose corn syrup has negative effects on the metabolism according to a 2017 medical review.

It also increases the risk for obesity even more than other caloric sweeteners, as we documented in our is AriZona Green Tea good for you article.
