I love how none of these comments account for fiber, something you won't get from granulated sugar but which you will absolutely get from any actual fruit, which at least one of these yogurts actually references in its label.

Fiber is not only good for you on its own for your gut health but will slow the rate of absorption of sugars, preventing sugar crashes and allowing your body to make use of the carbohydrates over time. It affects the glycemic index and is why real whole wheat/grain bread doesn't give you a sugar crash.
