https://ourworldindata.org/grapher/vegetable-consumption-per-capita betting this is where they sourced it, FAO presents it at the supply level, the per capita figures are OWID's doing

this sent me down a rabbithole and hot damn that website is rough to use

I found the first usable data digging into this one: https://www.fao.org/faostat/en/#data/FBS

with options looking like this (just hit select all to get all measures on that top right box):

seeing figures on the same order as whats listed in the OP:

except it's continued to increase lol
