hey eul ,
all the fruits and nuts you have mentioned are really health boosting. but i did not really understand ydo you wish to change your milk / yogurt with something ? i mean bcoz you are watching weight ? or any otherreason you want to avoid it for ? these fruits mixed with yogurt and milk, make a complete health packed drink, it comes with the goodness of the fruits , all vitamins and minerals intact and milk / yogurt add on to the protein content. overall making a nutrious drink. i dunt think there i anything wrong with the combination unless you have a reason .... plz let us know your motive for alteration, probably then we would be able to help you better.
