Added sugar is not necessarily problematic, but consumption of anti-thyroid substances like high amounts of PUFA (especially seed oils), chlorine, bromine, fluoride (in absence of iodine) can make it so, by way of increasing energy supply which is not properly consumed. Industrial pollutants like PFAS and hexane byproducts also play a role.
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.
