I kinda have the same question. I had a whipple from pancreatic cancer. I will use yogurt, almond milk, fruit and whey protein powder, I have also used egg protein powder. You can make up your own. Oh i put it in a blender and make a smoothie. The only problem with going to buy a smoothie, they put too much ice in them and they are expencive. Also, I am lazy, but you could juice veg. and fruits. I am sure you can get a book at the library and ask around if anyone has a juicer you can borrow. good luck dawnella
