Broccoli is an amazing vegetable loaded with vitamin C, A, K, B-complex vitamins and essential minerals like iron, zinc, phosphorus, potassium and phyto-nutrients. The high level of vitamin C works as a protection against common cold whereas the phyto-nutrients and antioxidants, especially sulforaphane and indoles help to flush out carcinogens from the body thereby lowering the risk of cancer. Sulforaphane present in this green vegetable reduces oxidative stress and slows down aging. The best way to juice broccoli is by washing it thoroughly and cutting it in to small pieces before putting it in the juicer.
