Conservatives trend towards “homey”, familiar, comfort foods and meat-heavy options. They are more likely than liberals to indulge in fast food and enjoy splurges like cheeseburgers or deep dish pizza. Their idea of international food is a “mainstream” option such as Italian.
Liberals are more likely to be adventuresome eaters, choosing international options such as Japanese or Thai. They eat fast food less frequently than conservatives, and when they do splurge on fast food they have a tendency to favor specialty, regional chains. Liberals are more likely to choose healthy or vegetarian alternatives when given the choice.
Although there are plenty of food-related differences that skew by political ideology, there’s still plenty of common ground for the dinner table. So there’s no need to let a little political disagreement get in the way of a great shared meal. (Thanks Marcy)
