Why a tiered sugar tax on soft drinks could reduce health inequality

The German cabinet has approved a tiered sugar levy on soft drinks, exempting beverages with less than 5 grams of sugar per 100 milliliters and imposing charges of 26 cents per litre for 5-7.9 grams and 32 cents per litre for 8 grams or more. Advocates argue that low-income and less-educated groups consume more sugary drinks, leading to higher rates of obesity and type-2 diabetes, so the tax could narrow health disparities.

By making sugary drinks more expensive, the policy aims to curb consumption and improve public health. The graduated rates also give producers an incentive to lower sugar levels, as seen in the United Kingdom where a similar scheme led to a substantial reduction in sugar content after its announcement. Supporters claim the tax is socially responsible because it does not keep unhealthy drinks artificially cheap and promotes healthier alternatives like water and unsweetened tea.
