I've noticed in my friends that there seems to be a need to push me into doing normal things, as if the appearance of normalcy somehow makes the cancer gone, and eating "real food" is one of those things -- Be sure that in your efforts to return him to normal in terms of how he ingests food, you don't cheat him out of getting all the nutrition he actually needs.

Eating can be hard work and it may be difficult to get enough calories of the right stuf inside, whereas the canned stuf contains all one needs in terms of both calories and additives -- Nutritionist told me that three cans of the 1.2 density stuf would give me all the vitamins, etc., for the daily requirements of a normal adult -- Some people are on a life-time diet of the canned food, so it's more than just a stop-gap measure.
