It turns out there was once a governmental body called the Office of the Coordinator of Inter-American Affairs, and they teamed up with Disney to create this animated film about humanity’s relationship with corn—or maize—spanning roughly 9,000 years. Apparently, some hungry hunters discovered that when animal food sources were limited, corn could help them survive. In those early days, bread often had a fishy flavor because sardines were planted alongside the kernels as offerings to ensure good harvests. (I do wonder why they didn’t just eat the fish themselves?). As civilizations like the Aztecs and Incas developed more complex rituals, even including human sacrifices, that fish taste disappeared. Eventually, scientists began selectively breeding corn plants to produce larger yields. The film mentions several foods we depend on today, although bread seems almost secondary, before it praises the practice of giving corn syrup to babies—ideally before they’ve even sprouted teeth. It's not immediately obvious what this upbeat animation is trying to achieve. Corn cultivation has spread extensively worldwide, and according to the data presented, over 40% of the U.S. crop goes to feeding pigs, so maybe it's a nudge to purchase more sausages? The film passes the time adequately while looking down on those who built Machu Picchu and the people who figured out that grinding corn allowed for far more than simply adding butter.
