Summary

This study aims to systematically evaluate the effect of Singapore's new front-of-pack non-alcoholic beverage labels, called Nutri-Grade, on the consumption of processed beverages. Using a fully functional grocery webstore, the investigators wish to assess the causal effect of the new labels on food and beverage purchase, sugar intake, and overall diet quality and examine how this effect varies by shoppers' income and education level.

The investigators' hypotheses about the effects of these new food labels, measured by the grams of sugar per serving (primary) of finalized shopping baskets, are as follows:

1. Hypotheses 1: The new sugar-sweetened beverage (SSB) labels will shift consumers toward healthier products. Sugar-sweetened beverages are any liquids that have been sweetened with one or more of the different forms of added sugars.
2. Hypotheses 2: The new SSB labels will reduce overall sugar and calories purchased and increase overall diet quality.
3. Hypotheses 3: Effects will be greater for those with low income/low education as they are least familiar with the nutrition facts panel and thus most likely to benefit from the new information.

Nutri-Grade labels

All beverage products in the arm are displayed with the Nutri-Grade label. This label was proposed by the Ministry of Health in Singapore to be implemented at the end of 2021. It will apply to all pre-packaged non-alcoholic beverages sold in Singapore. It will have four color-coded grades wherein Grade A, corresponding to the lowest sugar and saturated fat thresholds, will be in green and Grade D, corresponding to the highest sugar and saturated fat thresholds, will be in red.
