Children were included in this challenge study if according to parental report (1) the child's hyperactive behavior had been noticeably improved for at least 3 mo. as a result of adherence to the Feingold diet and (2) dietary violations such as those used in the study were reported to have a noticeable negative effect. Evaluations of 14 objective measures in a double-blind, cross-over design yielded no significant differences between diet infraction and noninfraction conditions. In addition to questioning the stated efficacy of the diet, findings suggest that one should not depend solely on parental report when evaluating a dietary effect and should also weight potential negative effect of adherence to the diet.
如果根据家长报告，满足以下条件的儿童可纳入本次激发试验研究：(1) 由于坚持费因戈尔德饮食，孩子的多动行为已显著改善至少3个月；(2) 据报告，如研究中所采用的饮食违规行为会产生显著负面影响。在双盲交叉设计中对14项客观指标进行评估，结果显示饮食违规和未违规情况之间没有显著差异。除了对该饮食所宣称的功效提出质疑外，研究结果还表明，在评估饮食效果时，不应仅依赖家长报告，还应权衡坚持该饮食可能产生的负面影响。
