General guidelines for post op TIF diet:
Weeks 1-4 you're very swollen still and you need to be on liquids and pureed foods (think baby's first food).
Weeks 5-8 soft foods (no mashed potatoes, rice, bread, or meat.)
Weeks 9-12 firmer foods but still staying away from potatoes, rice, bread, or steak
Make sure to chew foods to a liquid and eat very slowly. Keep your food to no more than 1/2 cup a meal.
Check with your Dr. to see if he/she agrees with above. On discharge you should have had a visit from the dietician to learn what foods were OK during the healing process. I hope this helps you.
