Question (As I have not donated):
Often you hear people given a snack and drink at the blood bank (normally sugar and grain based snacks) after donating blood.
Is the snack after donating blood highly advised by the blood bank? (do we need really need it - is a drink water or tea enough) - If food is required, do healthy eaters bring their own snack to eat (eg fruit or ,boiled egg + nuts) and drink provide tea/coffee without sugar.
What do you do?
