Consumer Group Warns of 'Skimpflation' as Cheaper Fish Replaces Mackerel

A consumer advocacy group has raised concerns about "skimpflation," a trend where manufacturers reduce the quality or quantity of products while maintaining the same price. This issue has come to the forefront with the increasing availability of "jack mackerel" on supermarket shelves as a substitute for traditional tinned mackerel.

Consumer group Which? has identified the sale of jack mackerel, a species noted for being less nutritious than its counterpart, as a prime example of this practice. The group is urging consumers to be aware of these changes in product offerings, which can subtly impact both the quality of food and its nutritional value without a corresponding decrease in cost.
