【简答题】
背景材料： 材料1：近年来，食品安全问题已成为社会关注的焦点问题之一。食品安全问题直接影响着消费者的生命和健康，然而我国目前还没有建立较为完善的食品安全教育体系，公民主要通过电视、广播、网络等大众媒体了解食品安全信息。而大多数食品安全问题都与化学有着密切的联系，因此在化学教学中进行食品安全教育是一个可行的方式。 材料2：2011年9月5日，央视财经频道《消费主张》栏目一则题为“杂味儿的味精”的报道，披露了青岛两家味精厂生产的味精中谷氨酸钠含量严重不足，除此之外，还含有超标的硫酸镁和食盐等杂质。 问题： （1）在化学教学中进行食品安全教育，体现了化学新课程的什么基本理念？ （2）列举一个可以渗透食品安全教育的化学教学内容。
