Unit2 同步检测 Ⅰ.阅读理解A Eating foods high in trans fats(反式脂肪) and saturated (饱和的) fats increases the risk of depressionom the universities of Navarra and Las Palmas，followed and analyzed the diet and lifestyle of over 12，000 volunteers over six years.When the study began，none of the participants had been diagnosed with depression；by the endfferers. “Participants with an increased consumption of trans fats presented up to a 48 percent increase in the risk of depression when they were compared to participants who did not consume these fats，”the head study author said.“The more trans fats were consumed，the greater harmful effect they produced on the volunteers.” The research team found，at the same time，that after assessing the effect of polyunsaturated fats made up of larger amounts of fish and vegetable oils and olive oil，these products are associated with a lower risk of suffering depression. The report，published in the online journal PLOS ONE，noted the research was performed on a European population that enjoys a relatively low intake of trans fats－making up only 0.4 percent of the total energy taken in by the volunteers.“Despite thiss like the United States，where the percentage of energy derived from these fats is around 2.5 percent.” The report pointed out that the current number of depression sufferers in the world is around 150 million people，and has increased in recent years.This rise is attributable，according to the authors，to great changes in the sources of fats consumed in western diets，where we have replaced certain types of beneficial fats in nuts，vegetable oils and fish with the saturated and trans fats found in meats，butter and other products such as mass-produced cakes and fast food. 【文章大意】　本文主要讲述了吃含有极高反式脂肪和饱和脂肪的垃圾食品会增加患抑郁症的几率。　　　　　　　　 B．Vegetable oils.ve oil.
