The History of Kale
Kale is a loose-leafed edible plant and is an ancient member of the Brassica family, which also includes numerous other cruciferous vegetables such as broccoli, cabbage, Brussels sprouts, and cauliflower.
The origin of kale dates back to some 2000 years ago when it was one of the most widely consumed green vegetables in the middle ages. In those times, it was an important staple in most people’s diets. The main reason behind its popularity back then is the fact that it is a very easy-to-grow vegetable and is also highly resistant to cold temperatures.
However, this wasn’t the case in France, and there is quite a debate about how or when the French ate this leafy vegetable.
Although kale was definitely grown and eaten in France, it was actually a part of the légume oublié category, which translates to ‘lost and forgotten vegetables’ in English. Compared to turnips and parsnips that were popularly grown in France, kale was a much-forgotten kind of vegetable, and surprisingly, many farmers didn’t even know what this vegetable was.
Even during the period of WWI and WWII, kale fell seriously out of fashion. This decline in its popularity that initially began during the middle ages made it quite a ‘love-it-hate-it’ kind of vegetable.
However, it wasn’t until many years later that kale made its way into the vegan lifestyle. It was primarily part of the American diet, but soon enough, people from all around the world began to discover different amazing varieties of kale and also the incredible nutritious benefits of each type.
