I published a report today based on Hunch data that examines how food preferences vary by political ideology. It has some findings that you’d probably find intuitive (conservatives favor homey, comfort food and meat-heavy options, while liberals trend towards more adventuresome and international cuisine). But it’s interesting to see hard data confirm these hypotheses.
I had an illustrator sum up the 7 page, 2,100 word report this way:

Conservatives favor homey staples and meat-heavy options

Liberals favor more international cuisine and vegetarian alternatives
