49The following appeared in a letter to the editor of a newsletter on health issues.
"For the past decade, most health experts have advised teenagers to avoid eating greasy foods in order to prevent acne and related skin conditions, but the number of teenagers who sought medical help for these skin problems has actually risen over the same period. In a recent study, teenagers who avoided greasy foods for a month reported approximately as many outbreaks of acne and related skin conditions as did those who ate an average of two servings of greasy food per day. Such data indicate that eating greasy foods is unlikely to be a cause of acne and related skin conditions. Therefore, health experts should no longer recommend that people avoid such foods."
作者的结论是therefore后面的,专家不应该在禁止人们吃油腻食品
但是,heath experts是有义务是大家避免其他疾病的
个人认为,这个点可以驳斥
