In this newsletter, the author claims that to use a kind of nutritional supplement - Ichthaid to prevent colds and therefore could lower the absenteeism in schools and workplaces. To support this contention, the author provides a study reports in East Meria and mentions that people who consume fish a lot are less likely to see the doctor for the treatment of colds. However, after a carefully examine, I find the argument unpersuasive for the following reasons:
First of all, the study provides from the author that fails to indicate the direct relationship with the cold and fish consumption. On one hand, in the argument the author does not explain the conclusion that fish consumption could be possible to prevent cold. By simply putting these two things together, the author has hastily generalized the conclusion of that. And it is very likely that there is a coincidence for the high consuming rates of the fish and the low numbers of people who went to see the doctor for the treatment of colds per year. On the other hand, the author absents to consider that people visit doctor in a low rates, does not mean that the real situation of cold is keep in a low rate as well. Perhaps that the numbers of the clinic in East Meria is pretty low and therefore cause a low rate in average. And the residents of East Meria might prefer to have some medicals at home rather than to visit the doctor while a cold happens. In short, without the considerations of these and other possibilities, the author's contention that totally based on the study cannot be stand as it claims.
In the second place, the author only focuses on the case that happens in a particular area, and with absence in the regional discrimination. For example, East Meria is probably located in the temperate zone, and in this sense cold is not a widely case happened in people's daily life. And another possibility is the residents in East Meria do have good health conditions in a general speaking, and colds are therefore less occurring in this area than others. Lacking the evidence that people in East Meria who eat fish a lot and do have some relationships with their health conditions, the author's argument that eating a substantial amount fish can prevent colds is unjustified.
Thirdly, even assuming that eating fish could be able to prevent colds in somehow, there is no evidence shows that Ichthaid could work efficacious to prevent colds as well. On one hand, the author does not provide anything about the evidence that be able to indicate the efficiency of Ichthaid, and therefore he cannot hastily asserts that this nutritional supplement derived from fish oil helps the way to prevent colds. And on another hand, the author also absents to consider other supplements from fish and might be work with much more efficacious than Ichthaid could be. Therefore, lacks the evidence that Ichthaid is really helpful with the way to prevent colds, the author's argument is fallacious, at least without evidence to support it.
Finally, even assuming that Ichthaid could be able to help with the treatment of colds, the author fails to conclude that the absenteeism of schools and workplaces can be reduced significantly with a promise. Common sense informs us that only to focus on lower the causes of cold will not good enough to help the reasons for other kinds of absenteeism. Such as the compassionate leaves or other sick leaves. Moreover, colds are the most frequently reasons to give for the absence, and that possibly might be cold is the most common reason for sick to ask a casual leave. Therefore, without the considerations of these causes, the author cannot to ensure that the absenteeism rate could be lower by simply using Ichthaid.
In sum, the author's argument about the Ichthaid to prevent cold and then lower absenteeism is unpersuasive as it stands. To bolster it, we need to know more about the fish consumption and cold prevention, and whether it is a specialized occurrence in East Meria. Further, the author also needs to show the efficiency of Ichthaid works as same as the nutrition getting directly from the fish. And finally, provides survey in order to ensure that the decrease of the causes of cold that could be a weight reason to lower absenteeism.
