Michelle, I am answering this question but I've recently become aware that PEG tubes vary in width and so in what they will accomodate easily I suspect. So someone else's answers may not be right for your husband.

I put all sorts of juices down my PEG--the only caution being that they have to not have any substantial pulp or be very thick or that can end up blocking the tube. I have also poured lots of green tea down my tube.

Back when my stricture was bad and I couldn't swallow at all, I would every day flush down the tube some V8 juice and some other kind of juice (Bolthouse Farms makes a blueberry/blackberry juice "smoothie" that is thin enough to use which I liked). I swear those juices made me feel better and as though I had more energy than when I was just using the jevity formula alone. Might have just been psychological though.
