In our explorations of plant-base foods (PBFs) in PubMed, it’s often striking that there are many excellent articles from non-US countries. So we did a survey in PubMed to measure different countries’ authorship of articles on PBFs, and we found that, indeed, several countries have a much higher proportion of their total articles on PBFs than the US.
The charts below show our data for all PBFs and for four specific foods or food groups. The charts are based on the percentage of articles from each county, not the total number of articles. So even though the total number of articles on PBFs by US authors may be higher than other countries, the proportion of articles on PBFs is substantially lower. [The charts are from a poster presented at MLA in 2016. For more details on our survey methods, see the poster.]
