I looked at the sugar intake of various countries and compared them to the prevalence of diabetes in these countries using the United Nations Food and Agricultural Association dataset.
In the coming month, I will update this post with the results from other datasets until it is complete. All datasets that are available are consistent with the above graphs, except Euromonitor. Euromonitor data costs $2000. If you would like to purchase the Euromonitor dataset for me to analyze and post the results from, please send me a private message.
