What are the ideologies underlying in Mayor Bloomberg's soda ban that are taken as granted?

          Today I would like to deconstruct Mayor Bloomberg's soda ban proposal and try to tackle the transparent ideologies that we are taking as granted. Below I have attached a newspaper article from Washington Post about mayors from various cities trying to fighting obesity by issuing policies to limit the use of food stamp to consume sugary drinks.

http://www.washingtonpost.com/national/health-science/18-mayors-including-nycs-call-for-testing-ways-to-limit-use-of-food-stamps-to-buy-soda/2013/06/18/20926598-d865-11e2-b418-9dfa095e125d_story.html

          Mayor Bloomberg's original proposal was to mandate all restaurants or shops that receive a letter grade from Department of Health to not sell sugary beverages of volume larger than 16 ounces. Clearly, as we saw in this news article, Mayor Bloomberg and other mayors were trying to fight obesity and reduce the rising healthcare cost under the following assumptions.

• Overconsumption of sugary beverages is the major cause of both adult and children obesity epidemic, diabetes, heart diseases, and gout. 
• Reducing on the consumption of sugary drinks would help people control their weight.
• Mandate reduction on the consumption of sugary drinks could efficiently restrict individuals' consumption of sugary drinks.
• The reduction in the size of the sugary drink can limit the amount of soda a person consumes although it may merely cause inconvenience for those who want to drink more than 16 ounces of sugary drinks.
• Having that food stamps are given as the governments' attempt to provide food assistance for low-incomers, limiting the use of food stamp to but sugary drinks would help the city governments to restrict low-incomers' consumption of sugary drink and thus reducing their risk of being another victim of the obesity epidemic.
• All people particularly low-incomers are lovers of sugary drinks and they use their food stamp money to buy sugary drinks for consumption.

Although Bloomberg's proposal did not mandatorily restricted individual's daily consumption of sugary drink, many angry New Yorkers were upset by his attempt to "nanny" them and "violate the freedom of consuming sugary drinks". And after all the law was overturned by NY state justice. But these above assumptions are what Mayor Bloomberg and other mayors taken for granted when they come up with this approach to public health policy. Not judging if their assumption are logically valid and despite of what really is Mayor Bloomberg's intention in restricting the size of sugary beverages restaurants or shops can sell, whether to fight obesity or some other reason, they are somehow promoting well-being and public health. But in a culture where sugary beverages are popularized among the majority of the population and having people taking their right of consumption for granted, Mayor Bloomberg's embracement of bodily fitness and healthier diet as his approach to public health policy is not appreciated by the mass public.
