Health associations have long been calling for a "fat tax"; taxes on foods that some nutritionists and researchers don't want us to eat or drink. Unfortunately, the lack of sound thinking behind vilifying sugary drinks or less healthful snacks has not changed, nor has the blunt, imprecise, and unfair nature of a "junk food" or "sugary drink" tax. Overly simplistic solutions to obesity that vilify an industry or food product are bad public policy. The reality is that "junk food" taxes or sugary drink taxes are ineffective instruments that fail to recognize the complex and manifold causes of obesity. It's time we put the idea of such taxes in their rightful place: the junk bin.
