Fruit Only Days

The eco committee have been discussing the idea of having some fruit only days for snack.  We first discussed this during health week as a way of encouraging our 5 a day of fruit and veg.  Yesterday it caused some debate.  Each rep was to poll their pals to gauge opinion.  Next week the Eco committee hope  to make a recommendation after their consultation.  What do you think have having a fruit/veg snack only day in school on a regular basis?  Would you commit to a 2 day week? 3 day?   It has been an interesting debate in class too.
