Diet Pepsi Ingredients
Diet Pepsi contains added caffeine. It does not come from a natural source like tea. Since caffeine is an added ingredient, it appears in the list of ingredients that you see on the label.
Ingredients: Carbonated Water, Caramel Color, Aspartame, Phosphoric Acid, Potassium Benzoate, Caffeine, Citric Acid, Natural Flavor, Acesulfame Potassium.
Cola manufacturers state that they add caffeine to cola to produce its unique taste. It reportedly provides a bitter flavor that helps balance the sweetness. Furthermore, caffeine certainly helps sales as about 85% of U.S. adults consume the stimulant daily.
The caffeine in Diet Pepsi is relatively similar to what is found in Pepsi, Coca-Cola, and Coke Zero, as examples. Its caffeine level is typically for a soda and much less than countless coffee and energy drinks.
Keep in mind that health agencies typically advise adults to consume no more than 400 mg of caffeine daily. That is almost 11.5 cans or roughly 138 ounces of Diet Pepsi. We think that it’s safe to say that most people don’t come close to drinking 400 mg of caffeine simply from Diet Pepsi.
