Do you mean the after-surgery diet?
I don't know of any "protein shakes" I would call good, or healthful either. Read the ingredients.
Just about all those things are corn syrup, water and milk, with some vitamins and flavoring. IMO You might be better off drinking a glass of nice fresh milk and taking a small daily vitamin. We don't need more sugar. Most vitamins aren't necessary either.
Eating a good, healthful diet of real food is the best way to go. If you can't chew food, use a food processor or other machine. Beef may be a bit hard, so use chicken or something else softer. I really like ground chicken instead of beef for burgers and chili.
