Can you be more specific then about what we're discussing, if it's not "ban things that the 10% is addicted to"?
The only thing I can really get behind is stricter controls on individual ingredients that are very clearly unhealthy and obviously don't need to be part of your diet (BPAs, trans fats, etc). Once you start messing with society's macros though it's fraught territory and very easy to do harm IMO.
