A growing stack of evidence shows compounds called glucosinolates found in crops like kale may suppress the development of cancer cells from the colon, lungs, liver, bladder, breast & stomach. Suttons & Exeter University tested various cruciferous veg for glucosinolates & Kale Black Magic showed by far the highest levels of all, with more than 5x the levels of some of the others. A newish, cut & come again variety, bred for the British climate, it makes a great addition to the diet but would look great in a potager border too!
