How long after sigmoidectomy can one begin eating fiber again? I understand that certain foods should be avoided, but no information tells me for how long one must abstain. My Dr. said that I could eat anything I want but to reduce fiber at first. Okay, I got that. I am 8 days into this and cooked some veggies and lentals until they were almost mush, then put them in the vitamix. I will try a small bowl of this however, I am still not certain if this is the right thing to do. I want better nutrition than white bread and meat, potatoes and pasta. Anyone know?
