Again there's a distinction between a chemical analysis perspective and a practical nutritional perspective. Freshly squeezed orange juice contains sugar to be sure, but in practice very few people guzzle the stuff to the point of destroying their health, whereas lots of people do precisely that with Coke.
"If it comes in a package, it's candy" is probably the correct rule. It's not that eating candy will kill you, but if you eat a bag of chips, drink some soda, and eat a packaged snack, the reality is that you have almost certainly just had a meal consisting entirely of what is best described as "candy." So don't do that regularly. :-)
