Fuck yeah.
Sugar is in everything, sugar makes shit food taste better, most processed food has high levels of sugar and flour, we receive enough sugar naturally, we don't need it introduced, added or hidden in other food.
Along with hydrogenated oils, the high constant intake of these things deficient in or void of; vitamins, minerals and enzymes and the repeated onslaught of sugar will eventually disrupt the finely tuned process causing some elements to remain in a constant state of activity.
Once the endochrine system is disturbed, shit happens and this causes many pathological symptoms.
I'm sure of it!
