Sugar in it self isn't bad, it is important in many bodily functions such as providing energy. Outlawing all sugar is very vague. There is two types of sugars that we eat; natural sugars, found in places such as milk (lactose) and fruits (fructose), and table sugar, (sucrose). It just people who taken in excess sugars which is stored in the body as fat, which then leads to health problems.
Instead of outlawing sugar, more money should be funding programs that educate the masses on sugar consumption. And if you what to outlaw something outlaw gum. In my opinion gum is completely useless and it most of time end up on the floor.
