One of the features of successful Journal Clubs in medicine is the availability of food (Sidorov, 1995; Alguire, 1998). This is particularly the case where Journal Clubs are built into training programmes and are likely to be held as a working lunch.
Providing some sort of snack for school-based Journal Clubs serves two main purposes. The first in unashamed bribery in order to get people to come. The second is an offer of sustenance at the end of a long day (the chances are probably high that you’ll tack it on after 3.30).
Any type of (socially acceptable) food is fine. Biscuits, as well-priced and almost universally loved, are an excellent choice.
