There's a very good reason why sugar is so "addictive" -- it's good for you! It's an obscenely easily digestible source of energy, whose products are used very easily by the cells. In the case of fructose, its consumption is relatively more insulin-friendly than the glucose-heavy starches. Sucrose is half glucose and half fructose.
Seriously "addictive" sugary foods are psychologically problematic usually for other reasons. Pure cane sugar is not very addictive when consumed alone. Try it.
