Studies have shown that eating three to five servings of cruciferous vegetables like cauliflower, broccoli and kale each week can significantly lower your risk of developing cancer. Anthocyanins — a group of antioxidants found in sweet potatoes — have been found to slow the growth of certain types of cancer cells in test-tube studies, including those of the bladder, colon, stomach, and breast.
