Abstract

In December 2022, Singapore implemented mandatory Nutri-Grade front-of-pack labels for beverages. Using household scanner data (April 2019-March 2024), we evaluated changes in sugar purchases and product formulation. Households reduced sugar purchases by 3.1 grams per day (-18%), and purchases of unhealthy beverages fell 44%. Reformulation and reassortment lowered sugar content by 1.16 grams per 100 milliliters (-21%) but increased sweetener and lactose use. Higher-income and nutritionally literate households showed larger reductions. Findings support mandatory labeling but highlight equity concerns and supplier substitution risks.
