OneOfMany –
No, they aren’t.
In Masechta Kallah it says specifically that it only refers to bread, or when eating in a gluttonous fashion. Here is the link to the source (I hope it doesn’t get deleted this time):http://hebrewbooks.org/pdfpager.aspx?req=37970&st=&pgnum=680. It’s on the bottom of the first column.
Rabbeinu Tam in Kiddushin (40b) says something similar, that it is referring to eating bread, which Tosafos explains as a meal. See the end of the bottom Tosafos here: http://www.hebrewbooks.org/shas.aspx?mesechta=20&daf=40b&format=pdf (according to the other opinion in Tosafos, this whole halacha doesn’t really apply the way we are understanding it here).
