After being voted for by an overwhelming majority of MPs, the tax on saturated fat led to inflation, cross-border shopping, job losses and huge administrative costs. It had very little effect on the consumption of saturated fat because Danish shoppers downgraded to cheaper brands from budget supermarkets, often in cheaper countries. It did, however, clobber the poor — as indirect taxes usually do.
Since it had a negligible impact on consumption, it is unlikely to have had any impact on health. Once it became clear that the fat tax was creating lots of costs and no benefits, an overwhelming majority of MPs voted to repeal it. In January 2013, 15 months after it was introduced, it was abolished.
