US Lags Behind The World In Plant-Based Food Research


Many other countries spend a much larger proportion of their research time and resources on plant-based foods than the United States does.

By Xiaomei Gu, Eric Rumsey and Janna Lawrence

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 chart above shows our data for all PBFs and the charts below show 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. The PubMed search strategy used to find plant-based foods in the chart above is described here.]
