In the USA, food prices are non-core inflation and most volatile indeed.

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.

Food prices in Norway are going up because the government keeps importing people who do not want to work, and then they give those people our tax money so that they can compete with us in the labour and food markets, which are heavily restricted. It has 0 things to do with the weather or some disease.

The main change is that the central bank dropped interest rates while inflation was already way above target (about twice the target inflation rate), and they did that to help the socialist party in govenment win the election, the problem is that dropping interest rates while inflation is already high and then while you still import more tax leeches results in a massive spike in inflation.
