There's way less sugar in fruit than there is in HFCS and/or table sugar laden jam. (ex: 1 tbsp of smuckers has 12g sugar, vs approximately 0.08g of sugar per every 1 actual raspberry.)
If you were to put a small dollop of jam on 1 cup of yogurt, then that'd be comparable to putting 150 actual raspberries in, at which point you'd definitely have more raspberries than yogurt to the point of hilarity/incredulity.
