Hard vegetables are best juiced, like carrots, cabbage, beets, roots etc.
Soft and juicy fruits, with some nuts or seeds added (almonds, flaxseeds, etc) to it, are best made in the blender, like all kinds of berries, mango, papaya, pineapple, banana, plums, pears, apples, oranges, lemon, lime, grapefruit etc.
