Never used food. The advantage is nice, but is it worth 1 action point?
Assuming a fight lasts some 4 or 5 rounds with a total of 4*4 (16) or 4*5 (20) AP then 1 AP is already 5% or 6% of the total AP the character spends. Is the advantage worth that? Usually not.
Taking food before the fight is very hectic and you work against the counter. Say you eat three things and need a round into the fight starting, then the first food already has decayed for four rounds.
Given there is not *that* many food around so you cannot run around fooded-up for every member and for every fight I guess the duration could get increased.
