#12 Grilled Fish
Grilled seafood should be avoided, because like grilled meat, the effect of the saturation in the fish on the grill surface can produce a carcinogenic effect. However, if it is baked in an oven or cooked on a stove top, fish is actually fantastic for you and has been linked to cancer prevention.
#11 Diet Soda
Diet soda has aspartame. Some of the concerns about cancer stem from the results of studies in rats published by a group of Italian researchers, which suggested aspartame might increase the risk of some blood-related cancers. Try to avoid sodas with aspartame as much as possible to reduce your risk.
