Cabbages are one of the oldest vegetables known. Throughout their long history they have often been thought of as food for the poor. Cabbages are a member of the Brassica family of vegetables. Unfortunately they are often overcooked which ruins their flavour and destroys their nutrients. There are many varieties of cabbages grown in New Zealand which vary from red, green or white, with smooth or crinkled leaves and round or oval in shape. Taste variations are subtle. As with most vegetables, specific variety names of the brassica group can be confusing as seed companies market similar products with different names. Cabbages are an excellent source of vitamin K and vitamin C. They also supply valuable amounts of vitamin A and B group vitamins, calcium, potassium and fiber. Cabbages contain compounds which research strongly indicates inhibit the development of some cancers.
