What did this study do and find?
This study evaluated the effects of health and environmental warning labels and taxes on red meat purchases using a randomized controlled trial in a realistic online supermarket (Warning labels, taxes, and a combination of warning labels and taxes all led to modest but statistically significant reductions in red meat purchases compared to a no-policy control.The condition that included both warning labels and taxes had the largest impact on red meat purchases and also reduced calories and saturated fat purchased.Warning labels led to lower perceived healthfulness and environmental sustainability of red meat, while taxes led to higher perceived cost.The policies’ impact on purchases was greatest for lower-educated and younger participants.
