In an ideal world, all government regulations are well thought out and limited to things that are minimally invasive to the citizen, and still allow the citizen to be free to make a choice. Nutrition labels are a good example of this. In the real world, many regulations are influenced by corporations to serve their own interests. The food pyramid is an example of this. Anyone aware of the latter should be skeptical of any proposed regulation, especially in the US. Is it in the best interest of the populace, or was it influenced to be in the best interest of a lobbying organization?
