One difference between the TIF and NF is the TIF has staples that food fibers can catch on. Even if the food goes through a blender it may be a problem because the fibers catch on the staples and tear the surgery out. I had the TIF in April and followed the diet on the TIF web site. In the first part of the diet I had Ensure 2/day, cottage cheese, some cream soups cooled and through the blender, strained soups, yogurt with no fruit, and milk. For the second part of the diet I ate pasta with tofu, mellon, soaked cereal, and runny mashed potatoes. Also stay away from acid producing foods, hot, cold and alcohol. I drank water, milk, apple juice, and Ensure. Watch for constipation. Following the diet is important to the success of your TIF. Good luck.
