Incidentally, you ever read the ingredients list of Fritos? If not, you're up for a pleasant surprise.
Ingredients: Corn, Corn Oil, and Salt. No Preservatives.
There are similarly simple ingredients in most plain potato chips. But corn chips and potato chips are usually FRIED!!
Chili Cheese Fritos Ingredients: Corn, Corn Oil, Salt and Chili Cheese. No Preservatives.
Salt is a preservative.
Your pedantry is not contributing to the conversation.
my first reaction was "they're reducing the sodium in pepsi the beverage." didn't seem to match up with a video circulating not too long ago that claims sodium was intentionally added at high levels in soft drinks (proportional to high fructose corn syrup to mask the taste of sodium).
if it's food snacks, i guess that makes more sense.
Colas have 35-50mg of sodium per can, depending on the brand.
