Many states, cities and municipalities (NY City, the state of California, Montgomery County, MD) have moved to ban trans fats.
If you don't know what trans fats are, go here: https://www.americanheart.org/presenter.jhtml?identifier=3045792
To assume that the reports that trans fats are dangerous to the health of the individual are, in fact, true. This is a situation where something that the individual is doing (eating things that are bad for them) does not have a DIRECT impact on the public.
Based on public health law can you help me justify banning trans fats AND create an argument against banning them?
