Abstract in brief

Over the past 50 years, global food supplies have generally expanded in terms of calories, protein, fat, and weight, with a shift towards more energy-dense foods, while the diversity of crop species contributing to these supplies has changed but not been precisely quantified.
The variety of crop commodities in national food supplies has increased, and their contributions have become more evenly distributed, leading to a decrease in dominance of specific crops and a shift towards globally important cereal and oil crops, resulting in more similar food compositions across countries.
This increasing homogeneity suggests a move toward a global standard of food supply that is species-rich at the national level but species-poor overall, raising concerns about interdependence among countries and emphasizing the need for nutritional development to ensure food security.

national food supplies globally have become increasingly similar in composition, based upon a suite of truly global crop plants. https://t.co/sNGTPajldi
