阅读《看穿食品包装上的噱头》，完成9~12题。（共11分）

①“不含防腐剂”、“不含人工色素”……究竟该如何看待食品包装上“自卖自夸”的诱人说辞？这里选一些有代表性的说法，来解剖其中的潜台词和产品真相。

②“不含防腐剂”，可没说不含其他食品添加剂。搞氧化剂、增鲜剂之类都有可能在里面。

③很多食品本来就不需要用防腐剂，如罐头，一些极干的食品，含盐和糖极高的食品。因为罐头在制作过程中能把里面的细菌和芽孢彻底杀灭，最后密封包装，细菌进不去，所以它不需要防腐剂。没有水，细菌无法繁殖。大量盐和糖能起到防腐剂的作用。

④不过，盐和糖含量太高，比含有防腐剂还要糟糕。因为大量的盐对健康的危害，要比微量的防腐剂厉害的多。比如，一些酱油、咸菜等宣称“不含防腐剂”，但它们通常都是咸味特浓，甚至再加糖掩盖的产品。

⑤“不含人工色素”，意思是说，这里面还是含有色素的。只不过这些色素不是合成色素，而是从天然原料中提取出来的，如红曲色素、紫胶红等。

⑥对号称“纯天然”的食品也要辩明其真相。商场里那种红色或绿色的“果汁”[甲]产品，看起来很像是水果浓缩而成，包装上还画着大大的水果图像。但仔细看了原料说明后才发现，它含的原果汁只有20%左右，也就是说，其中的80%都是水、糖、香精、色素、增稠剂等辅料。

⑦“不含蔗糖”的说法常见于糊粉类产品，或饼干、点心之类。“不含蔗糖”[乙]，即不含我们常吃的白砂糖。中老年人、糖尿病人和肥胖者，都容易受其吸引。其实，这真是一大陷阱。

⑧能让血糖快速上升的，远不止蔗糖。精致淀粉令血糖上升的速度已够快了，而以淀粉为原料制作出来的麦芽糊精、麦芽糖浆、葡萄糖浆等，都比蔗糖有过之而无不及。在那些声称“无蔗糖”的产品中，却常能看到这些配料。糖尿病人要是选择它们，那可真不如直接吃大米饭算了。

⑨从营养价值来说，无蔗糖了不意味比其他产品含营养素更高。不加蔗糖，往往用淀粉、糊精、油脂之类代替，除了提供能量升高血糖之外，对人没什么帮助。问题还在于，它们还常给人一种“高档”滋补[丙]的美妙感觉。
