ELI5: If all ingested carbohydrates are just reduced to glucose anyway, what makes "simple" carbs (soda, pastry, Wonder bread) different compared to "complex" carbs (whole wheat, rice)?

Simple carbs are broken down very quickly, while complex ones are broken down much more slowly. Complex ones offer a more stable source of energy. You'd have to eat a lot more of simple ones to get the same result.

Complex ones also have other compounds in them that are helpful to metabolism in general.
