不好意思,阿狗迟到了.
这周一直在忙课程设计,今天下午又一门考试.

A recent study concludes that the most way to reduce the risk of fractures in later life is to take twice the recommended dose of vitamin D and calcium daily. To support this conclusion, the argument cites that a three-year study followed a group of French women after taken double recommended amount of vitamin D and calcium and light weightlifting program showed a much lower rate of hip fractures than average. However, this study relies on a series of unsubstantiated assumptions, and is therefore unpersuasive as it stands.

The threshold problem of this argument is that the study unfairly overlooks many other possibilities that this group of women have a lower rate of hip fracture. As the argument described, this group women taking twice the recommended dose of vitamin D and calcium has participated in a light weightlifting program at the same time. Maybe it is this light weightlifting that brings on the reduction in the rate of hip fracture, but not the vitamin D and calcium. And perhaps due to adequate exercises in their early life, these women had a lower rate of hip fracture than average before this study. Without ruling out other possibilities to ensure that taking double dose of vitamin D and calcium are the immediate cause of the reduction in rate of hip fracture, this recommendation is questionable.

Furthermore, the argument lack sufficient evidence to validate that to reduce the rate of fracture this method by taking double dose of vitamin D and calcium can be useful for all the olds in the world. Maybe on account of pleasant environment and appropriate dietary habits, the French people have a better health in their bones since they were born. And the conditions such as temperature, climate and sunlight varying from region to region, this therapy might not be applied to all zones successfully. For instance, the Chinese traditional medicine might not react on the western person well. And those Korean dietetic therapies might only have the applicability on eastern people. Moreover, this argument only mentioned the women, how about the men? Can it be applied to them? Lacking further information, this assumption that taking double dose of vitamin D and calcium has a good effect on all the people is invalidated.

Even if we accept that taking double of recommended dose of vitamin D and calcium has an immediate effect on rate of fracture’s reduction, this argument also fails to convince us the double dose has the best curative effect. Maybe the triple dose or the fourfold dose has better effect even than the double.

In conclusion, this argument is unconvincing as it stands on the questionable assumption. Before ruling out all other possible explanations about the cause of the reduction in the rate of fracture, we cannot summarize that taking double dose of vitamin D and calcium is the right causation, solely. To bolster, the author should provide further detailed information to ensure us this therapy will react well on all the worldwide people. And the author should also validate that taking double dose have the best curative effect, not other amount.
