It's the whole economy. Labor costs are up. This drives labor costs in food production/transport/retail up (or else workers will switch jobs). Hence food prices. And demand remaining high is what keeps labor costs up. So, food prices can go up and down even if food-specific demand is inelastic (that is, even if people eat the same amount and quality of food regardless of price). FWIW I've found my food demand not to be 100% inelastic -- I have changed where I get fast food as a result of some price increases, and I've found that in times when I'm not making a steady income, I find it easier to maintain or lose weight.
