Food and nutrition occupy an increasingly prevalent space on the web, and
dishes and recipes shared online provide an invaluable mirror into culinary
cultures and attitudes around the world. More specifically, ingredients,
flavors, and nutrition information become strong signals of the taste
preferences of individuals and civilizations. However, there is little
understanding of these palate varieties. In this paper, we present a
large-scale study of recipes published on the web and their content, aiming to
understand cuisines and culinary habits around the world. Using a database of
more than 157K recipes from over 200 different cuisines, we analyze
ingredients, flavors, and nutritional values which distinguish dishes from
different regions, and use this knowledge to assess the predictability of
recipes from different cuisines. We then use country health statistics to
understand the relation between these factors and health indicators of
different nations, such as obesity, diabetes, migration, and health
expenditure. Our results confirm the strong effects of geographical and
cultural similarities on recipes, health indicators, and culinary preferences
across the globe.
