What you’re referring to is (and I’m over simplifying here) glucose versus sucrose. Potatoes have glucose, and aren’t sweet. Twinkies and the like are full of sugar aka sucrose (which is half fructose) which is the real issue. Avoiding all food with fructose is a good idea. Not only is it bad because only your liver can process it (none of your other cells can use it, unlike glucose) but fructose is in some emerging studies to prohibit lepton signaling. Leptin is the hormone that tells your brain you’re full and no longer need to eat. Many obese people have impaired signaling. Food addition is not a good term. Food addictive addiction is better. No one would eat the cookies if it wasn’t for the sugar. Or get addicted to coffee without the caffeine. Sugar is the same as alcohol - it has calories, sure, so could be considered an energy source. But it has no other nutritional value. Yet it is regarded as a food. One cigarette is not harmful, yet we know smoking everyday will cause you some ill effects. It’s the same with sugar. An acute dose in itself is not dangerous. But over time it does.
