3. Protease Inhibitors
You may have never heard this term before, but now you should remember it and pay attention to its importance. This element can be found in soybean. Eat this natural product to prevent colon cancer. Other types of cancer that protease inhibitors can fight are liver cancer, mouth cancer, and lung cancer. Your normal and healthy cells will not convert to malignant cells since soybeans contain compounds that block the action of the enzymes called trypsin and chymotrypsin. Protease inhibitors are known for their suppressive effect and can inhibit oncogene processes.

4. Polyacetylene
Parsley is one of the sources of polyacetylene. This is what can ruin benzopyrene – a potent carcinogen. Also, it blocks the action of prostaglandins.
