'Skimpflation' warning as tinned mackerel alternative hits more supermarket shelves

A growing trend of supermarkets selling a cheaper, less nutritious alternative to tinned mackerel, jack mackerel, is being labeled as 'skimpflation' by a consumer group. Princes has replaced traditional mackerel with jack mackerel due to dwindling stocks of Atlantic mackerel, prompting consumer complaints about taste and labeling. Experts urge manufacturers to be transparent about these changes.
