One potential problem with taxing less nutritious foods is that they may:

The concern with taxing less nutritious foods lies in the potential that such measures may not significantly change consumer behavior or food consumption patterns. This can happen for several reasons, including the strong preferences or habits individuals might have regarding certain foods that are deemed less nutritious. If the tax is not substantial enough to deter purchasing or if consumers do not perceive it as a significant cost, they may continue to buy these foods regardless of the tax.

Moreover, individuals may prioritize convenience, taste, or availability over health considerations, meaning that a tax alone may not be effective in promoting healthier choices. Therefore, while the intention behind the tax is to steer consumers towards healthier options, if it fails to motivate a change in purchasing behavior, it may not achieve its public health goals, making it a potential problem associated with this approach.

Public opposition, economic impact on lower-income individuals, and targeting manufacturers instead of consumers are important considerations, but they do not address the direct impact on actual consumption patterns, which could undermine the effectiveness of such a tax initiative in improving community nutrition.
