Cabbage
The cancer research team at the Francis Crick Institute in the United Kingdom did research and found that eating cabbage altered the lining of the intestines. Every 4-5 days the lining of the bowels and intestines regenerates, without the right diet these cells will grow out of control.
The active ingredient can only be accessed when you chew the food. Once it gets to the lower bowels it changes the behavior of the stem cells stopping them from growing out of control.
Even if you are predisposed to these types of cancers. Meaning if you have had a family history of colon, bowel or intestinal cancers eating a serving everyday will stop the cancer from happening. They found that even if you already have tumors Cabbage will stop the tumors from growing.
