Fig. 2: Visualization of the predicted average weekly total carbon footprint and saturated fatty acid intake associated with each of the 113,400 possible menu combinations for an average consumer.
From: Dish swap across a weekly menu can deliver health and sustainability gains
a,b, The results for Week 1 (a) and for Week 2 (b). The purple dashed line indicates the mean predicted carbon footprint (g CO2e) and the pink dashed line indicates the mean predicted saturated fatty acid intake (g). In both plots, the red circle indicates the predicted values associated with the baseline menu and the green circle indicates the predicted values for the swapped menu. The pink triangle indicates the observed values under the baseline menu, and the blue triangle indicates those under the swapped menu. Mismatch between observed and predicted values can lead to observed values that lie beyond the edge of the predicted values. A plausible explanation is that participants were more likely to select healthier and more sustainable dishes in the online task.
