Abstract: consort to the article, the caramel food coloring used in soda contains electromotive force cancer-causing compounds. The potential carcinogens are 4-methylimidazole (4-MEI) and 2-methylimidazole (2-MEI), according to the Center for Science in the Public Interest (CSPI).

Critique: The article seems to hold several(prenominal) merit based upon the sole fact that the author has observational proof the back up the claim that the caramel coloring can causal agency cancer. Other than that, the article does little to deviate the reader of one way of thinking or the other. evening the experiments themselves leave more unbeliefs than they do answers.

Another question is, how high of a dose has to be taken to develop a cancer? The high doses used to experiment on the rats is still much higher than that found in a regular bottle of soda. Finally, the fact that the article claims that the FDA does not shortly list 4-MEI and 2-MEI as known human carcinogens should be a clear indication that the caramel coloring, while taken in normal dosages, does not cause cancer.
