16GMO foods
Genetically modified foods (also called GMOs or genetically modified organisms) are foods that have had their genetic structure artificially modified in some way. Many scientists argue that GMOs cannot be carcinogenic since humans have been selectively breeding crops for centuries.
But the truth is that GMOs have not been around for long enough for researchers to make any strong claims one way or another. Therefore, they cannot be unquestioningly accepted into a cancer-free diet until further research is done on the subject.
Alternative: Buy healthy food that is marked as non-GMO. If you can afford it, organic food is the best way to go.
