Should a Sin Tax on Sugary-Drinks be implemented to fight obesity in America?

In my college government class, we had to write a paper on what Americans can do to fight the obesity epidemic, and a Sugary-Drink tax is something that came up quite a bit when I was researching, and it really intrigued me.

60% of adults and 15% of children are obese in the United States, and a Gallup poll found that 48% of Americans consume soft drinks every day. Would taxation of this be an ethical step to fighting the obesity epidemic?

Some cities and countries already have this type of soda tax, and some have even banned free refills on soft drinks and have had results. I also found a lot of research papers basing their initial hypothesis off the significant success of the cigarette Sin Tax.

I also saw many articles suggesting it would only affect those with lower income and that it is unethical for the government to try and control food decisions of its citizens.

I see both sides as I researched both sides and they each have some valid points, but I’d like to hear what you all have to say.
