I got into sweet potatoes big-time when we lived in the States. They are very popular in the Caribbean, and date back a long way. Indeed, Columbus brought them to Europe, and you will find them in every supermarket in England now.
Sweet potatoes contain starch, which is energy. They provide some protein, vitamin C, vitamin E and a huge amount of carotenoids, including betacarotene. They are considered to be strong in combating cancer.
Sweet potatoes are delicious in homemade juice. Try combining apple, celery, carrot and sweet potato.
Mashing this delicious vegetable with others, such as ordinary potatoes, parsnips or swede, is a great way to introduce them to children. Get them organically grown if you can.
