TOPIC: ARGUMENT142 - 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.

By stating that the the correlation between high iron levels and hearts deisease and is morst probably a result of the correlation between red meat and heart disease, the author provides a useful but not strong convincing conclusion, for this argument suffers from several logic flaws. At first, whether the study is reliable is qustionable. In addition, the writer unfairly assumes that the correlation between red meat and heart disease has something to do with the iron. He also unreasonable conclude a the relatinship between these two correlation.
In fact, we have no enough evidence to believe the study's result that high levels of iron caused the increased risk of heart desease. As we know, we do not eat pure iron. Instead, we abssord iron elements from various foods. For example, spinnach also has affluent iron in it. It's possible that this study is established on such a kind of diets so that we have no sufficient data to draw the claim that it is the iron in these food that cause increased heart disease. After all, iron in different place remais a different form. So, we can't accept the result of the study, let alone acknowledge that this iron has something to do with red meat.
It true that there is a well established link between red meat and heart disease, but the assumption that iron in red meat is actual cause of the heart disease is prmature. The arguer fails to take into account and rule out other factors in red meat also may lead to higher risk of heart disease. After all, red meat consists not only iron. Perhaps, some special protein in red meat or certain carbohydrates in it bring some harm to one's heart. Another possible explainaton coms from the way people cook red meat, maybe, the habit of cooking them in a widely accepted method instead of red meat itself result more chances a one get heart deseases.
Fially, even the study's result and the assumption mentioned above are both well founded. We can hardly reach the conclusion that the correlation of red meat with heart disease are the cause of the correlation of iron with heart disease. It eqaully possible that theie relaionship is on the contary.
In sum, this argument ignore what kind of food are from in the study and arguer some what simply equate red meat with iron. To well present this argument ,more surveys are needed.
