帮忙看看这作文题怎么写？

The following appeared in the health section of a magazine on trends and lifestyles: “ People who use the artificial sweetener aspartame are better off consuming sugar, since aspartame can actually contribute to weight gain rather than weight loss. For example, high levels of aspartame have been shown to trigger a craving for food by depleting the brain of a chemical that registers satiety, or the sense of being full. Furthermore, studies suggest that sugars, if consumed after at least 45 minutes of continuous exercise, actually enhance the body’s ability to burn fat. Consequently, those who drink aspartame-sweetened juices after exercise will also lose this calorie-burning benefit. Thus it appears that people consuming aspartame rather than sugar are unlikely to achieve their dietary goals.”
提示上说research 和studies的不可信，但是。。但是。。这两个不是一回事么，那就么什么可以写的了啊，大家快帮我想想

亲，我想了两个角度反驳，
1、high levels of aspartame 如何如何，但是没有给出如果进食少量的例子
2、consumed after at least 45 minutes of continuous exercise ，如何如何，但是没有给出其它时间段的测试
最后，你还可以引申一下，作者没有考虑一些特殊人群，如糖尿病人，不能吃糖，但他们可以吃少量的阿巴斯甜，这样他们的身体比吃糖相对健康。
