[quote]Yes you can only pick one[/quote] And picking just one won't fix anything. Though technically you can make one and two happen at the same time by removing the subsidies for food that goes into fast and processed food, and moving them to healthier food, and possibly taxing it more so on top of that. McDonalds and the like will drop it for less costly alternatives; the healthier food. Education is the next one but people in general aren't built to think abstractly about long term consequences. Too many people still think in only the short term. Another thing that apparently is a problem is just access. Grocery stores are becoming scarce in places that need them the most and are being edged out by fast food joints.
