1、尽量选择优质、信誉好的大厂家生产的产品。
既然我们无法杜绝使用过食品添加剂的食品，但我们尽量选择优质信誉好大的生产企业因为这些产品能够严格执行国家关于食品添加剂的管理规定。而那些质量低劣的地下作坊，生产出相当一部分产品则属于滥用或超标使用食品添加剂，人体若长期大量摄入这些成分则有害无益。
2、学会看食品配料表，尽量买添加剂少的食品。
总之，对待食品添加剂，尽量少吃，不吃最好!!!

Tip: If the failing expression is known to be legally null/missing, either specify a default value with myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing. (These only cover the last step of the expression; to cover the whole expression, use parenthessis: (myOptionVar.foo)!myDefault, (myOptionVar.foo)??
