The UK government is reviewing the Soft Drinks Industry Levy (SDIL) with consideration to include milk-based drinks, such as milkshakes and RTD coffees, due to their high sugar content. This move is supported by health campaigners like Action on Sugar, citing the need for healthier market options and a comprehensive approach to dietary health policies. However, the dairy industry argues that milk-based drinks provide essential nutrients like calcium, protein, and vitamins, and extending the levy could have unintended negative health consequences. The review also highlights the need for addressing the high sugar content in pre-packaged milkshakes and milky coffee drinks, compared to the lower sugar intake from milk-based drinks by young people. The outcome of this review could influence global health policies regarding sugar taxes and milk-based products.
