You can do it yourself. I used to drink a lot of sweetened soda. I switched to diet, then stopped. Regular sugar-sweetened drinks taste sickeningly sweet to me now, and diet drinks taste like chemicals.
Once you break the habit, your sense of taste recovers and you realize how nasty these drinks are. Most people get started on them as kids when you don't have a nuanced sense of taste and really crave sweet stuff.
Same. I used to drink multiple Cokes a day. I switched to Diet Coke sometime in my late 20s. In my 30s I cut back to one Diet Coke a day and about 4 years ago in my mid 40s I switched over to carbonated water when I crave something fizzy but still limit myself to one a day most days. Coffee and plain water have replaced the soda I used to drink.
This was all done over time as I realized I needed to change my diet to keep weight off and I wasn't really enjoying my daily soda(s) anyway. With an actual intent, one could drop soda within a few months easily and never miss it.
Until you realize caffeine has long term negative effects on sleep even at low doses. Only the pure water drinkers can claim any moral high ground! (I’m not one of them)
Why would there be? Sugar is good. Products with sugar are good. Self control is also good. People can like products with sugar and exercise self control, so there will always be a demand for mass produced products with sugar, and that's a good thing.
Self control doesn't reduce the amount of sugar that's already added to the soda I would like to drink. It just means I don't get to drink it. I have to go find low-sugar sodas. I would like to have more options.
No chance there would be a switch. Consumer tastes and eduction aren't going to change.
Short of that, I wish there was clearer and more consistent labeling. I avoid sugar and sweeteners. Its annoying to be in the mood for a flavored drink, see something that claims to be zero sugar/all natural/etc, grab it in a hurry, then discover on the first sip its got erythritol in it. I read the label, but sometimes I miss it. My preferred options are unsweetened iced tea, coffee, or flavored water. Those are reliable, but can get boring.
Food is generally easier. I just avoid anything that has (or should have) a lot of carbs as a rule when looking for convenient pre-packaged food. No point in sweetening a can of sardines...
I just started brewing my own tea and coffee, unsweetened. Snack foods are a bit harder, but we are better off eating whole fruits and vegetables anyway.
