I suggested that. Its a good idea. It's not just an incentive for people to buy healthier food, its an incentive for food producers and providers to make their products healthier. How about a weight based income tax deduction? If your weight in relation to you age/height/build, per your doctor, are in some specified target zone, you get an extra $50 bucks back on your taxes. Yay! We could do the same with blood pressure, blood sugar, and cholesterol.
