Kale: The Superfood with a Complex History | SoundHeal

Kale, a member of the Brassica family, has been cultivated for over 2,000 years, with records of its use dating back to ancient Rome. However, its modern popularity as a 'superfood' is a relatively recent phenomenon, with the US kale market growing from $10 million in 2007 to over $100 million in 2017. Despite its widespread adoption, kale has also been criticized for its high water usage, with some farms requiring up to 1 gallon of water per pound of kale produced. The kale industry has also been linked to issues of gentrification and cultural appropriation, with some arguing that the trendy green has been co-opted by wealthy, urban elites. Nevertheless, kale remains a staple in many health-conscious households, with a single serving providing over 200% of the daily recommended intake of vitamin A. As the global demand for kale continues to grow, it is likely that the industry will face increasing scrutiny over its environmental and social impact.
