Hello, My 60 yr old husband just got home from the hospital. He had his appendix removed 8 days ago, which the surgeon said had burst four days prior. His digestive system went to sleep for about 6 days, and now is working. He has NO appetite, and can only eat a few spoons ,or sips of anything. He has been eating water, juice, cream soup, yogurt. What foods do you recommend? Any that promote healing? What foods are best for him?
