Extended Data Fig. 3: Prevalence of inadequate B-vitamin intake (%) and counts of B-vitamin-source species per country.

Inadequate B-vitamin intake is represented by the Prevalence of Inadequate Micronutrient Intake Index¹. Light grey represents missing inadequate-intake data; blue, low inadequate intake and many source species; red, high inadequate intake and few source species; and brown, high inadequate intake and many source species. Brown countries are those that could benefit most, nutritionally, from their edible plant diversity. The axes labels on the legend in Extended Data Fig. 3a apply to the other subplots. The numerical ranges for each colour (indicated in the legends) were generated using Fisher natural breaks classification method⁷⁶ and differ for each subplot for improved visualisation.
