Information about food preservation doesn't help with casual RP, to be certain...but it helps me build realistic cities and areas. Concepts like sources of fresh water, possible crops or sources of food, and means of preservation have a great impact on the development of cities, especially in a world without modern means to do it.
So, the point is, I don't have my players keep a list of specifically what foods they carry and so on; that information allows me to make richer descriptions of their market transactions and build more detailed, realistic, and "living" cities and towns.
With many foods, as well, means of preparation make a huge difference. Many foods, if prepared improperly, are either poisonous or simply cannot be digested and provide no nutritive value. Plot hooks can revolve around such simple matters. For instance...everyone in the city eats salted beef. So where's the salt come from? Historically, salt was worth its weight in gold, and battles erupted in the streets of old Europe between butchers and tax collectors, because salt was being heavily taxed and butchers need a whole lot of it to salt meat. So there's a salt mine, or salt gathered from seawater. And if there's a salt mine, it's just as valuable as a gold mine with the added bonus that you can't eat gold.
Where the money is, you will find a plot to draw in your adventurers.
