But all of this takes me back to my original position. Much of this can be accomplished just by being aware of what you're eating and how much of it you're eating.
Nobody is saying otherwise, but that's missing the point. Most people aren't going to do all that, especially every meal.
The idea is to reduce heart attacks and strokes on a population-wide level and reduce the burden on the health care system. You seem to be thinking extremely individualistically but some issues are more effectively addressed on a larger scale. If you really want to prevent deaths then reducing sodium in the food supply is just more effective than telling people to cook.
