You are not really making a case for the greatness of safe pvp here...
For safe pvp uni is way better than anything else. a lot of semi-serious fights are done with food off and the only healing you get is from uni
And well...i'm baffled by people complaining about praying anywhere else than pking- if the fights don't matter, there is no reason to complain, if they do something, so can you.
Uni, SS, and blood barrage is enough healing for basically everything except back to back specs / PJing. which you can avoid easily if you know how to keep distance and have a reliable barrage. barrage is not nearly as reliable in pking because the higher magic attack items (arcane, ahrims) are usually cost prohibitive - thus defending (healing) against melee attacks is a much larger issue in pking than safe pvp.
the only other way to die is to get outbridded, and if you're outbridded in pking you'll pretty much die regardless of food.
also, most of the people who actually have a decent amount of skill will bring summ pots, which are actually better than any kind of food.
