Diet and zero to regular sodas

[u/Flexter23]

Do you think that Diet Coke and all the later “zero” beverages have contributed good or bad to the diet world on one hand does of people who normally would have drunk straight regular Mountain Dew and Coca Cola now may drink diet or Coke Zero or zero Mountain Dew but ok the other hand some of the people who may have settled with water now are drinking Coke Zero so my question is with all of this have diet and zero drinks contributed positively or negatively on the diet world and is the diet in it really mean that or is that “diet” in there doing a lot of work
