In Norway our food prices has gone up by more than 4 in one month while we are destroying any capacity for local production while we have protectionism that would make Trump blush. How is that not newsworthy, but this is?
Food prices go up because of random weather events (or locus or disease). USA beef prices are skyrocketing because of some new disease for example.
Anyone who says that a monthly food price change is an underlying indicator of overall inflation is simply lying to you.
