Impose sales tax on foods with unhealthy and harmful ingredients.

Impose sales tax on all the foods that contain harmful ingredients or use harmful ingredients during the manufacturing process, as well as using unhealthy quantities of otherwise not harmful ingredients (such as way too much sodium in the soups or adding sugar to fruit juices). The many harmful ingredients that are well known to health-conscious people, such as MSG, dies and colorings, aspartame, corn syrup are used in alarming numbers of foods. By imposing sales tax on such foods you kill two birds with the same stone - you get money and you subtly influence the general public, especially less educated people and children, to eat healthier.
