142.The article entitled 'Eating Iron' in last month's issue of Eating for Health reported that a recent study found a correlation between high levels of iron in the diet and an increased risk of heart disease. Further, it is well established that there is a link between large amounts of red meat in the diet and heart disease, and red meat is high in iron. On the basis of the study and the well-established link between red meat and heart disease, we can conclude that the correlation between high iron levels and heart disease, then, is most probably a function of the correlation between red meat and heart disease.

The conclusion that the correlation between high iron levels and heart disease is most probably a function of that between red meat and heart disease suffers from several vital fallacies during the reasoning.
First, the arguer cites a dubious survey to indicate the correlation between the high levels of iron in the diet and an increased risk of heart disease. There are no evidences whether the survey has a reasonable process at scientific respect. It is possible that the informants in the investigation suffer from congenital heart disease which has no correlation with the level of iron in their diets. However, they coincidentally eat a lot of iron in their daily diet, which causes the surveyor think that it is the high level of iron in their diet that results in the heart disease. Without ruling out such possibilities, I can not simply accept that there is any correlation between the level of iron in people’s diet and the increased risk of heart disease.
Secondly, it is doubtful whether the level of iron in the red meat is notably higher than other food. The arguer provides no data information which makes the reasoning unconvincing. It is possible that the quantity of iron in chicken is much higher than that in red meat. Without certain data unimpeachably proving the notably higher level of iron in the red meat compared with other food, it can not be accepted that the level of iron in the iron in the red meat is so high that it can cause the increased risk of heart disease.
In addition, I can not simply accept the dubious reasoning to prove that the high levels of iron in the red meat arouse the correlation between the red meat and heart disease. Even though there is high level of iron in red meat, there is no evidence that the level of other substances is lower than that of iron. It is probable that the fat, which is also stored in a large amount in red meat, that leads to the appearance of heart disease. Moreover, chances are certain unknown substance in red meat enhance the tendency of watching dracula movies, which is the actual reason why red meat in diet has a certain correlation with heart disease. Without ruling out such possibilities, it is too arbitrary to draw the conclusion that the high level of iron in the red meat results in the correlation between red meat and heart disease.
To sum up, not only are the evidences in the argument insufficient, the reasoning process is also impeachable, which makes the conclusion arbitrary at best as it stands. |
