Chinese:吃“垃圾食品”有哪些害处？
类别: 餐饮食品
问题:
什么是垃圾食品？吃垃圾食品都有哪些害处？
回答:
1.油炸食品
此类食品热量高，含有较高的油脂和氧化物质，经常进食易导致肥胖；是导致高脂血症和冠心病的最危险食品。在油炸过程中，往往产生大量的致癌物质。已经有研究表明，常吃油炸食物的人，其部分癌症的发病率远远高于不吃或极少进食油炸食物的人群。
2.罐头类食品
不论是水果类罐头，还是肉类罐头，其中的营养素都遭到大量的破坏，特别是各类维生素几乎被破坏殆尽。另外，罐头制品中的蛋白质常常出现变性，使其消化吸收率大为降低，营养价值大幅度“缩水”。还有，很多水果类罐头含有较高的糖分，并以液体为载体被摄入人体，使糖分的吸收率因之大为增高牞可在进食后短时间内导致血糖大幅攀升，胰腺负荷加重。同时，由于能量较高，有导致肥胖之嫌。
3.腌制食品
在腌制过程中，需要大量放盐，这会导致此类食物钠盐含量超标，造成常常进食腌制食品者肾脏的负担加重，发生高血压的风险增高。还有，食品在腌制过程中可产生大量的致癌物质亚硝胺，导致鼻咽癌等恶性肿瘤的发病风险增高。此外，由于高浓度的盐分可严重损害胃肠道粘膜，故常进食腌制食品者，胃肠炎症和溃疡的发病率较高。
4.加工的肉类食品（火腿肠等）
这类食物含有一定量的亚硝酸盐，故可能有导致癌症的潜在风险。此外，由于添加防腐剂、增色剂和保色剂等，造成人体肝脏负担加重。还有，火腿等制品大多为高钠食品，大量进食可导致盐分摄入过高，造成血压波动及肾功能损害。
5.肥肉和动物内脏类食物
虽然含有一定量的yz蛋白、维生素和矿物质，但肥肉和动物内脏类食物所含有的大量饱和脂肪和胆固醇，已经被确定为导致心脏病最重要的两类膳食因素。现已明确，长期大量进食动物内脏类食物可大幅度地增高患心血管疾病和恶性肿瘤（如结肠癌、乳腺癌）的发生风险。
6.奶油制品
常吃奶油类制品可导致体重增加，甚至出现血糖和血脂升高。饭前食用奶油蛋糕等，还会降低食欲。高脂肪和高糖成分常常影响胃肠排空，甚至导致胃食管反流。很多人在空腹进食奶油制品后出现反酸、烧心等症状。
7.方便面
属于高盐、高脂、低维生素、低矿物质一类食物。一方面，因盐分含量高增加了肾负荷，会升高血压；另一方面，含有一定的人造脂肪（反式脂肪酸），对心血管有相当大的负面影响。加之含有防腐剂和香精，可能对肝脏等有潜在的不利影响。
8.烧烤类食品
含有强致癌物质三苯四丙吡。
9.冷冻甜点
包括冰淇淋、雪糕等。这类食品有三大问题：因含有较高的奶油，易导致肥胖；因高糖，可降低食欲；还可能因为温度低而刺激胃肠道。
10.果脯、话梅和蜜饯类食物
含有亚硝酸盐，在人体内可结合胺形成潜在的致癌物质亚硝酸胺；含有香精等添加剂可能损害肝脏等脏器；含有较高盐分可能导致血压升高和肾脏负担加重。
