A few weeks ago there was a nice article in the Washington Post about a misguided vision emphasizing vegetables vs row crops as the focus for a sustainable food system:
We need to feed a growing planet. Vegetables aren't the answer. https://www.washingtonpost.com/lifestyle/food/we-need-to-feed-a-growing-planet-vegetables-arent-the-answer/2016/12/15/f0ffeb3e-c177-11e6-8422-eac61c0ef74d_story.html
I recently re-watched Food, Inc. One of the most egregious and misleading themes I get from that movie is that farm subsidies and our 'industrial' food system leads to a monoculture of mostly corn and soybeans that threatens both our health and environment. The WaPo article clearly explains why a shift away from row crops or commodity based cropping systems toward more vegetables is both non-pragmatic and more threatening to sustainably feeding the world.
There are a number of myths about commodity agriculture, monoculture, farm subsidies, and large scale agriculture, unfortunately many retailers and food products companies know how to exploit them.
