The argument that eating soy on a regular basis helps in preventing chronic fatigue and depression due to the inherent phytochemicals called isoflavones, which have been found to possess disease–preventing properties may seem logical at first glance. However, the conclusion relies upon assumptions for which there is no clear evidence and upon terms which lack definition.
First, the writer states that soy has properties to fight diseases as it has phytochemicals called isoflavones. However, there is no clear evidence stating whether it has specific fighting properties for chronic depression and fatigue. The evidence on which the argument is based is logically flawed. Chronic depression and fatigue is much more different than other normal diseases. Soy may be effective against bacterial and viral infections but there is no evidence proving that it is equally effective in fighting chronic depression and fatigue. Author should have stated specific research results proving the abilities of soy against chronic depression to back up his argument.
Furthermore, chronic depression and fatigue are types of disease which are born by one’s lifestyle and living rather than any bacterial or viral infection. The writer takes the lifestyle of people of North America and Asia at par which makes the argument implausible. North American’s can have a much more hectic schedule and their work environment can be painstaking as compared to Asians due to which such problems are bound to creep in their life. Perhaps, the argument can be stronger if the results from a survey conducted on the average working hours of Asian’s and North American’s can be stated.
Finally, the writer highlights that North American’s suffer 9 times more chronic fatigue and 31 times more chronic depression than do people living on the continent of Asia but he fails to recognize that chronic disease and fatigue can also be traced in Asian’s. Even if there is one Asian suffering from chronic disease and fatigue, who eats regular soy 20 grams a day can make the argument flawed. There is a high probability that such problems are present in people living in Asia, even if they are sparse, they will prove that Soy is not the necessary ailment for chronic disease and fatigue.
In conclusion, the writer requires the support of evidence demonstrating that Soy has properties fighting chronic depression rather than disease preventing properties. Research evidence on such facts can truly make the argument plausible. Argument should be well balanced by stating the prevalent lifestyles of North American’s and Asian’s along with conducting a survey in Asia testifying total absence of chronic depression and fatigue in regular Soy eating people
