你一定知道你是怎样被告知要给你的孩子吃有机食品因为杀虫剂会导致他们患上癌症的。是的，从技术上来说，在化学品和疾病之间确实存在联系，但是这在任何一个管制良好的国家这样的危险都微乎其微。
还有一种威胁是你没有被告知的。预防癌症的最佳办法之一就是大量食用水果和蔬菜。有机产品比用通常方式生产的产品要昂贵10%到20%，因此我们大多数人在“选用有机产品”时自然数量就会购买得少一些。
当你选用更为昂贵的有机产品，而把你的孩子每天摄入的水果和蔬菜量减少了0.03克（那是半粒米的重量），那么患癌症的总体危险是增加了，而不是下降了。如果因为你选用有机产品而导致你在20年间哪怕少买了一只苹果，你的孩子夜会遭遇更大的危险。
