My wife had PC and found it difficult to eat also. Had a G-J bypass and for some time was unable to eat. We experimented. We found a local apple cider which had protein and vitemins added that worked as a supplement. Puddings, fruit salad, soft fruit bars, even peanut butter cups, some of the relatively bland small microwavable soups worked, baby food, tomato soup, chicken noodle soup, gravy and mashed potatoes, some cereals, Ensure or Boost. Many will not understand this, but for the ill persons good, the caregiver must be unrelenting regarding encouraging the ill person to eat. To be honest this all brings back bad memories, but I sure hope some of these help. It's just the most miserable experience to have to watch your loved one go through.
