Maybe I just won't read the ingredients

Why are my favorite yogurt flavors the ones that could never be found in nature and certainly could never be considered "healthy?" Cinnamon Roll. Spice Cake. Red Velvet Cake. White Chocolate Raspberry. Boston Cream Pie. (Are we sensing a trend here?) And for some reason, I feel it's okay, because hey - the yogurt is fat free, while Boston Cream Pie certainly isn't. But at the same time, why can't I just pick something nice like cherry.
