Hippies believed that healthier food was integral to dismantling the status quo and, in turn, started health food stores, espoused vegetarian diets, and cultivated organic food, which they found to be a welcome alternative to the over-commercialized farming industry. In the decades since the movement’s decline, many of its practices have been absorbed by the mainstream.

How the Great Depression still shapes the way Americans eat

From fortified foods to nutrition labels, the legacy of an early financial crisis lives on in kitchens across the United States.
