The following memo appeared in the newsletter of the West Meria Public Health Council.
'An innovative treatment has come to our attention that promises to significantly reduce absenteeism in our schools and workplaces. A study reports that in nearby East Meria, where fish consumption is very high, people visit the doctor only once or twice per year for the treatment of colds. Clearly, eating a substantial amount of fish can prevent colds. Since colds are the reason most frequently given for absences from school and work, we recommend the daily use of Ichthaid, a nutritional supplement derived from fish oil, as a good way to prevent colds and lower absenteeism.'
----------------------------------------------------
The memo points out that according to the phenomenon happened in East Meria, it is a good way to use lchthaid, a nutritional supplement from fish oil, to prevent colds and lower absenteeism in West Meria. This recommenndation seems to be logical at the first glance; however, the further analysis in this argument will reveal how groundless it is.
First of all, there is no direct evidences show that the decreasing of cases for people visit the doctor for cold is due to the high fish consumption in East Meria. It is possible that the residents take some medicine themselves instead of going to the hospital. It is equal possible that the improvement of environment causes that phenomenon. In short, it is hasty to contribute the lower cold cases to eating fish.
Secondly, though colds are perhaps one of the reason causing the absences, there are still many other factors influence the rate of attending. Possibility the condition of traffic in West Meria is so bad that many people have to waste much time on the road. The schedule for the factories and schools in that place is also a possible element leading the absences. If the work time in East Meria is 9 o'clock while the one in West Meria is 8 o'clock, it is easily understood that the rate of absences in the former area is lower than the later one. Considering cold for the primary reason of absences makes the conclusion less persuasive.
Last but not least, daily use of lchthaid instead of direct fish consumption can not be proved that it will prevent colds effectively. The effect for decreasing colds by eating fish may be produced by some other parts in fish, such as some organic of fish, instead of fish oil. In addition, granted that the fish oil has the function to lessen colds, the lchthaid also does not represent the effective part of fish oil. What is destroyed in the process of producing the supplement from fish oil is also possible the main factors for reducing the colds.
Consequently, it seems accessible for the author in the newsletter to suggest the daily use of lchthaid, since it is natural for the citizens in West Meria to improve their healthy levels and work efficiency. However, before any final decisions are made, the inhabitants and police makers in the area should evaluate all the possible alternatives and reasons for decreasing the cold cases.
