Medical researchers at John Hopkins University have discovered that broccoli is comprised of high levels of compounds that prevent cancer. One of those compounds, sulforaphane, is also found in broccoli sprouts and is believed to inhibit the growth of cancer stem cells. It is also beneficial in assisting the liver in processing toxins and carcinogens that may be harmful to health. Studies at Ulster University concluded that consuming approximately 100 grams of sprouted vegetables daily helps protect the body from the DNA damage that is associated with cancer.
