It appears that my husband finds anything that is not freshly made (soups, smoothies) tastes "chemically." He has always loved Jello but now finds it so unpleasant that he can't bring himself to eat it. If you are planning to get all your calories from food, it is going to be hard. Our dietitian told us that it's all very well to subsist on soups and smoothies but my husband will be missing some of the essential vitamins and minerals, which you can get in Ensure and Boost. Please try and stay ahead of the game in every respect -- hydration, nutrients, pain management. Don't wait until there is a crisis.
