Argument 142
The author asserts that the high level of iron in diet is related to the increase the risk of heart disease. He indicates that a well-established correlation between the red meat and the heart disease, and the red meat is of great amount of iron. Due to the reason above, he conclude that it is high level of iron that response for causing heart disease. Unfortunately, the writer has three important flaws in his reasoning.
Firstly, there is no evidence to approval that the red meat is the main element that leading to the disease in heart. The passage only informs that the relation between the heart disease and great amount of red meat in diet without point out what kind of link between them. It is perfectly probable that the red meat may be the good way to protect our body away from such disease. The writer fails to show us the concrete link in the proof.
Secondly, even assuming that the red meat may cause the heart disease, the link between level of iron and disease cannot be established. For example, in a class, there is a student who makes a mistake and none of them know who did it on earth. We cannot judge that the student who wears white clothes makes the mistake, by the evidence that the number of students who dress in white is the biggest. Therefore, the assertion above is unwarranted.
Thirdly, even assuming that the iron level link to the risk of heart disease, we cannot conclude that such level is the function of the correlation between the red meat and the heart disease. The author provides no evidence to illustrate that if there is any other reason of red meat to act on the heart disease.
To sum up, the writer might give us more information to demonstrate that it is the iron that makes the heart disease broke out. And the link between red meat and such disease should be point out. To make more clearly, if any other elements in red meat could correlate to the heart disease should also be displayed.
