While I like the idea of not wasting a ton of money on food during progression from deaths. I think having the food persist 100% through death may effect the food market to heavy. What might be nice is with every death you lose 25% of the remaining duration till its gone. This would help a bit on food costs, while still keeping the market flowing.
Ex. Food has 30min left, you die, now it has 22.5min. You die again at 10min, well now it has 7.5min.
PS: 25% was just a number, not sure if that would even be a good middle point. Maybe 50% would work better.
