ARGUMENT35 - The following appeared in the summary of a study on headaches suffered by the residents of Mentis." Salicylates are members of the same chemical family as aspirin, a medicine used to treat headaches. Although many foods are naturally rich in salicylates, for the past several decades food-processing companies have also been adding salicylates to foods as preservatives. This rise in the commercial use of salicylates has been found to correlate with a steady decline in the average number of headaches reported by participants in our twenty-year study. Recently, food-processing companies have found that salicylates can also be used as flavor additives for foods. With this new use for salicylates, we can expect a continued steady decline in the number of headaches suffered by the average citizen of Mentia."水杨酸酯和用来治疗头痛的药物--阿司匹林是同一类化合物。尽管很多食品天然富含水杨酸酯，过去几十年中食品加工公司仍然在食品中加入它来作为防腐剂。这种水杨酸酯在商业上的使用被发现与我们为期20年研究的参加者所报告的头痛发病的平均数量下降是相关的。最近，食品加工公司发现水杨酸酯也可以被用作食品香料。根据这种水杨酸酯的新用途，我们可以预期Mentia居民患头痛症的数量将会持续稳步下降。提纲：1.水杨酸酯虽然和阿司匹林是一类化合物，但是否具有同一功效尚不得知.即使有，但当被加入食品中是否还有功效也不得知      2.所给的证据不能证明对水杨酸酯进行商业用途就是减少头痛发病人数的决定因素。      3.忽视并未排除食物中的水杨酸所带来的副作用

In this argument ,the arguer claims the new use for salicylate can lead to a continued steady decline in the number of headaches suffered by the average citizen of Mentia.To support his view, the arguer provide us a evidence(provide sb. with sth.) that salicylates,members of the same chemical family as aspirin, widely used in the food-processing as preservatives for the past several decades has been found to correlate with a steady decline in the average number of headaches reported by participants in twenty-year study. A careful examination of this argument would reveal the flaws in several aspects.

First of all, the argument fails to tell us that the salicylates have the same function in healing headache as aspirin. For instance, although salicylates and aspirin belong to the same kind of compound, however, compound is too complex to be judged, even a little difference in the structure can result in huge gap in function. And even if they have it, it is hard to know the function can still have when added in food.

In addition, the evidence exists some questions. Firstly the number of participants is unknown. If there is  a few participants surveyed ,the evidence will be lack of creadibility. Secondly, the fact the salicylate in food determine the decline in the average number of headaches reported by participants is open to doubt. Actually we can only found that the commercial use of the salicylates in food and the decline of the people who got headaches had a relationship on time from the argument. There are other factors should be considered. For example, most participants may have a bad eating habit which causes the headaches. They noticed that reason and began to change it during the past twenty years. Or most people had headaches due to the hard pressure from work, study and mentality. And with the increasing times they went to see the psychologist, their pressure gradually reduced therefore their headaches could be healed. These factors all could result in the same outcome, but the arguer fails to take into accountthem and wrongly treat the correlation as determining factor.

Finally, the argument wrongly ignores the negative effects of the use of salicylates in food .Because the salicylates are also a kind of chemical substances that their function must be taken into deep investigation to eliminate its negative effects.
Above all, the argument is not persuasive as it stands. To convince us, the arguer should present more information and evidence about the sample surveyed ,the great benefits of salicylates in food on treating headaches and demonstrating that the salcylate in food have not any negative effects.
