I believe the SSB (Statistics Norway) numbers are more like ~10% for food and non-alcoholic drinks [1], it depends a lot on what you look at. Culturally the Mediterraneans have a very different relationship to food - but looking at Eurostat, we're basically on the low end of average [2]?

(Also, the VAT reduction in light of the recent govt-assembled expert panel arguing for the exact opposite as one of the best ways of taxing high-income high-consumption households without hurting lower income groups is... fun.)
