Seeds in Pureed Food

Should I avoid seeds such as are found in berries and tomatoes? I will come home from the hospital on pureed foods and I don't want to mess it up! Would it be ok if I pureed seedless cucumber, tomatoes and red bell pepper with some lemon juice and salt? What should I avoid? I love gazpacho and thought a non-spicy version of that might be a good switch from sweet stuff. I don't like any kind of beans, so I thought I could maybe add tofu as well. I appreciate any thoughts. Friday the 13th is right around the corner!

My Dr. said to avoid foods with seeds(berries, tomatoes etc) for 6 weeks as they might irritate the staple area.  I know others have said their Dr. didn't have a problem with it. 

Ditto to the reply.
