My dad has had a peg tube for about two years now. As others have said the doctors have told him that he can put anything down it as long as it is in a liquid time form. He also has been taking in 8-10 cans of food. What kind of food is your husband on? My dad has been on Promote with fiber and it seems to have helped him quite a bit. He has been maintaining his weight since he's been on it. Hope everything works out for you!
