Just watched a documentary about sugar and sugar substitutes. People gladly buy all sorts of high-sugar foods if you just put "no added sugar" on them.
The reality is that avoiding high-sugar foods is hard. If you look at the nutrition facts on the packaging, you can easily be deceived:
Freeze-dried packages often don't state the amount for the prepared product, some products contain air/CO2 and others contain starches easily broken down into sugar.
Ordinary consumers want shortcuts.
