NRF8.3, Nutrient-Rich Food Index 8.3; GHGE, greenhouse gas emissions. Price calculated in British Pounds (GBP). Raw p values were analyzed using Bonferroni correction, and * show those values that were considered statistically significant; the strength of the correlation was defined using the following values: 0.00-0.19 “very weak”; 0.20-0.39 “weak” 0.40-0.59 “moderate”; 0.60-0.79 “strong”; 0.80-1.0 “very strong”.
