Barley

Whole-grain barley or pot barley - and other whole grains, such as rye and oats, contain phytic acid which has been shown to inhibit the growth of cancers. Barley is particularly rich in chemicals called protease inhibitors, which also have properties that combat cancer, including breast and bowel cancer. Whole grains are also high in fibre, which helps to keep the digestive and circulatory systems healthy.
