"Right now, kale is enjoying a moment. Kale is considered a superfood, rich with vitamins and minerals, but it is also an increasingly classy food. Kale is presently positioned firmly in the category of foods enjoyed by those rich in cultural capital, though fortunately you don't need economic capital to acquire it. Kale is now something people feel that they need to learn to eat and cook, to be initiated into, or even to feel smug about enjoying."
— Sara Davis on the impact of social factors on food preferences, on the website Table Matters.
