Canned Tomatoes:
Tomatoes are exceptionally dangerous due to their high acidity, which seems to cause BPA to leech from the lining of the can into the tomatoes themselves.
Processed Meats:
Processed meats contain numerous chemicals and preservatives, including sodium nitrates, which make them, look appealing and fresh but are well known carcinogens.
Salmon:
Salmon contains cancer causing compounds such as pesticides, antibiotics, PCBs, and even flame retardants. It also contains high levels of mercury, and cancer causing dioxins.
Potato Chips:
Potato chips are fried in high temperatures to make them crispy but this also causes them to make a material called acrylamide, a known carcinogen that is also found in cigarettes. Eating just 1 once of potato chips per day caused an average 2 pound weight gain in one year.
