由于速冻食物一般局限于几个品种,常吃会造成营养摄入不均衡。
Because of quick-frozen food generally limited to a few varieties, often eat can cause nutrition disequilibrium. 
食品速冻后,食物中的脂肪会缓慢氧化,维生素也在缓慢分解。所以,速冻食品的营养价值无法和新鲜食物相比。
Quick-frozen food, the food will be slow to the fat oxidation, vitamins are broken down slowly. So, quick-frozen food nutrition value cannot be compared with fresh food. 
超市的冰柜口往往是敞开的,人们对各种食品翻来翻去,温度不可能一直保持在-18℃。况且,速冻食品很难在加工、运输等过程中一直保持-18℃的低温。研究表明,食物在-1℃-8℃之间存放,很多维生素的损失比0℃-4℃还要快,温度的变化不但会破坏速冻食品的营养含量,而且会加速食品变质。
The supermarket freezers is often an open mouth, for a variety of food to people, can't keep on - 18 ℃ temperature. Besides, quick-frozen food is hard to in the course of processing, transportation and other remained - 18 ℃ low temperature. Research shows that food in 1 ℃ 8 ℃ between storage and a lot of vitamin loss faster than 0 ℃ to 4 ℃, the change in temperature will not only destroy the nutritional content of the frozen food, and will accelerate food spoilage.
