They did not express any indication that they didn’t understand why ice cream is often recommended, so you don’t need to be explaining it. The point of the comment is that kids don’t understand what’s going on, only hear about the ice cream thing, and then want the same procedure just so they can eat ice cream for a week.

The ice cream was a lie.

After I had my tonsils removed, even the thought of solid food was out of the question. It was just too painful.

You can have as much ice cream as you want. What they don't tell you is you won't want any. :P

Wouldn't the exposed nerves make the pain of "brain freeze" more likely?

Anyway, the relationship of tonsils and ice cream was established by Richard Scarry in "What do people do all day?" [0]

I thought tryptophan used to be added to icecream in the 70's and 80's until the tryptophan scare that caused Eosinophilia–myalgia.

Makes sense. I was very jealous of my friends at the time but I never took mine out.

I just get mad tonsil stones now. lol

I encourage you to read the book “Madeline” for more information on this phenomenon.
