复杂句子,请教

Very few patients have allergic migraine reactions as children live migraine-free adult lives once they have eliminated from their diets foods to which they have been demonstrated to be allergic.

这是OG10-CR-102中的D选项, 不知道啥意思.

请教.

我直译下：很少有病人再有migraine过敏反应一旦他们去掉那些有过敏反应的食品时，就像儿童过着像成年人过无migraine的生活一样，

哦，谢谢！这个child lives magrine-free adult lives 原来是这个意思．
