Fiber Nuts

Fiber Nuts is a fictional cereal mentioned in two episodes.

History
Fiber Nuts are first mentioned (and seen) in iWas a Pageant Girl. Spencer gives a box to Leslie and Alison (Spencer's and Freddie's dates) since they were starving and wanted to eat dinner while him and Freddie where too preoccupied with their game. Freddie mentions that it is a quality cereal.

It is also mentioned in iGot a Hot Room when Spencer offers cereal to Carly before he sends her to get milk so he could set up her birthday breakfast.

Trivia
Originally, the name of the cereal was supposed to be "Great Nuts." However, the network requested that Dan Schneider change the name, because they felt it sounded too similar to the real cereal "Grape Nuts."
