A 2007 USDA - commissioned report by the Institute of Medicine — part of the National Academies of Science — specifically advised against
allowing artificial sweeteners in foods sold in elementary
school vending machines or
canteens for several reasons, including safety.
As in 2015, the 2016 research showed that for some
schools (28 per cent in 2015/34 per cent in 2016) it was important that provision was made for cash based payers,
allowing children or parents to bring cash into
schools for various items, whilst in many secondary
schools pupil's still queue to pay the money into a cash re-filer in the
canteen, requiring students to take cash into
school.
