After realizing the canned formula for my husband was synthethic food and a lot of sugar I tried adding fresh carrot juice and other fruits and veggies along with protein shakes and yogurt. (I used a good food processor and ran things through a strainer to make sure.) He had trouble maintaining weight even with over 2500 calories so I tried adding the more healthy calories. At first I was nervous I would clog the tube but we always got everything down it just took awhile longer at times. A nurse told us Coke would take care of any clogs but my husband found a chop stick fit great to give a little more push when needed. Thank goodness the feeding tube is now a thing of the pass but was much needed then especially since he did lose over 35 pounds. He never thought he'd be back at his college day weight.
