KRNR station in HS has smoothies made with non-fat yogurt.
There are juices at Aloha Isle in MK, but I'm not sure if they are fresh.
Kona Cafe has some juice and smoothies as well. Boma has a juice that sounds similar to the one at Kona (passionfruit, orange, guava). And I'm sure there are more than these.
There are lots of places with fresh whole fruit, though!!
