TOPIC: ARGUMENT162 - A recent study shows that people living on the continent of North America suffer 9 times more chronic fatigue and 31 times more chronic depression than do people living on the continent of Asia. Interestingly, Asians, on average, eat 20 grams of soy per day, whereas North Americans eat virtually none. It turns out that soy contains phytochemicals called isoflavones, which have been found to possess disease-preventing properties. Thus, North Americans should consider eating soy on a regular basis as a way of preventing fatigue and depression.

Although the arguer's desire of peventing fatigue and depression for people living North American is laudable, the recommendation of considering eating soy on a regular basis in daily life might be abortive, since the arguer unreasonably assumes that the soy is responsibe for the less fatigue and  depression of people living in Asian than those in North American.


there are many alternative explainations to the situation that people in North American suffer more chronic fatigue and chronic depression. As we all know, a person usually feel more tired when under more pressure. However, the arguer fails to compare the work atmospher of this two districts, maybe the residents of North American are busy or more devoted in work, leading them more easily depressed. Moreover, other foods rather than soy possibly result in their more times of fatigue and depression, because we know that those living in North American have a very different life style with those living in Asian. Specificaly, many drinks such as coffe and many grains such as maise  which are produced in North Amercan alone, how can we ignore these things influence on the residents?  Before we rule out these possibilities, we can accept the arguer's conclusion.


In additon, the retionship of the so called isoflavoned with chronic fatigue and chronic depression is not soundly founded.  There exist no evidence infoms us that the disease-preventing probperties are specially effective for the fatigue and chroinc pression. It may be useful for many disease, but whther it bring a significant effect to the fatigue and depression, which more involve in one's spirtit is sitll open to doubt. Thus, perhaps other chemicals in soy or other food lead to the more fatigue and depression.


Even if we accept that the soy prevents Asians from suffering from fatigue and depression, we have no reasons to assumes that the same soy will be useful for North Americans. After all, the people of two places are not same to each other. Possibly, some foods of North Americans bodies may counteract the function of soy. Moreover, if the North Americans will accept the new food is still open to doubt.

Overall, this argument is not reasonable as it stands, to ensure the recommendation really work, more direct surveys are needed.
