Ice cream IS
good for you.
As long as it isn't done by the pint, quart of gallon daily or even five nights/mornings/afternoons each week. (Or used as a way to push a pizza through your innards)
Seriously, it kept me going in 2005-06 when I was in one of my digestive woes. But I was sort of sensible...only 2 or 3 pints per week (to help maintain weight after sudden 20+ pound loss).
