Better nutrition can have a lot to do with the transition to democracy: the more protein-rich, high-quality foods appear in a society's diet, the higher the likelihood of democratic reforms. Apparently, a richer diet is associated with an increase in the middle class, which tends towards economic and political independence and democracy-fostering values. Andrey Shcherbak has found, based on a cross-country comparative study using data on 157 countries, that a change in people's eating habits can serve as a predictor of impending political change. His findings are published in the paper 'A Recipe for the Democracy? The Spread of the European Diet and Political Change'.
