Thanks for the detailed reply. and for drawing me towards the core claims. In fact point 2, which I believe is the main argument, after reading the article again, is at odds with the “inflation” hypothesis, at least if we define inflation as a long-term trend of increasing food prices. The systematic overproduction of agricultural product by rich countries for food security has actually kept global prices low, even with the increase in demand from population growth. The recent movements in the price index are not obviously part of a long term trend (and with all that passed in 2020-21 it will be difficult to distinguish what is a trend and what is a one-off shock). I would like to read an article that looks at these themes in more depth.
