Frozen foods have less nutrients than fresh food–as we have already cleared that this is a major myth regarding frozen foods. It was seen that fresh fruits and vegetables usually lose nutrients more rapidly than canned or frozen products. Fresh produce loses vitamins upon refrigerated storage over time, while their frozen counterparts retain these nutrients equally so or better. The concentrations measured in frozen produce generally resembled those observed in the corresponding fresh produce prior to refrigerated storage.
Freezing will kill all the bacteria – yes and no, as certain bacteria may die at a freezing temperature, but not all. Some bacteria can survive freezing temperatures. Freezing to 0degF (-17.8deg C) inactivates any microbes, bacteria, yeasts and moulds present in food, most of them enter a dormant state and stay alive in the frozen food or liquid.
Once thawed, however, these microbes can again become active, multiplying under the right conditions to levels that can lead to foodborne illness. It’s the heating of the food, which will destroy most of them. (Thawing is the process of taking a frozen product from frozen to a temperature (usually above 0degC) where there is no residual ice, i.e. “defrosting”. Thawing is often considered as simply the reversal of the freezing process.)
Frozen foods are processed foods – yes & no. Yes, if the frozen food itself is processed food like frozen pizzas, processed meats, frozen fried foods. But you don’t freeze only processed foods, but extremely healthy fruits and vegetables too. For e.g. frozen peas, carrots, fresh meats, fruits, berries etc. Another way to check the quality of processed foods is by reading the ingredient list behind it. The list should be minimal in terms of preservatives and additives.
冷冻食品的营养成分比新鲜食品少——科学已经解释过了，这是关于冷冻食品的一个谣言。研究发现，新鲜水果和蔬菜通常比罐装或冷冻产品更快地失去营养，随着时间的推移，新鲜农产品不冷藏的话会失去部分维生素，而冷冻农产品则会很好地保留这些物质，在冷冻农产品中测量到的维生素浓度通常与冷藏前在相应的新鲜农产品中观察到的浓度相似。
冷冻会杀死所有细菌——是的，但也不是，因为某些细菌可能会在冷冻温度下死亡，但这并不是全部。很多细菌都可以在低温下存活。冷冻至零华氏度 (约-17.8摄氏度) 食物中仍然存在的一些微生物：细菌、酵母菌和霉菌会失活，其中大部分会进入休眠状态并在冷冻食品或液体中存活。一旦解冻，这些微生物就会再次活跃起来，在适当的条件下繁殖到可能导致食源性疾病的地步。给食物加热，会杀死大部分微生物，但是会使部分微生物从冷冻状态转为活跃状态，即“解冻”。（解冻通常被认为是冷冻过程的简单逆转）。
冷冻食品通常经过加工——大多数冷冻食品本身是加工食品，如冷冻比萨、加工肉类、冷冻油炸食品。但你不能只冷冻加工食品，还可以冷冻一些健康的蔬菜和水果。例如冷冻豌豆、胡萝卜、新鲜肉类、水果、浆果等。你最好还是检查一些加工食品质量，阅读一下食品背后的成分表，以及是否有防腐剂和添加剂。

Frozen food has gained quite a popular status because there is no one who doesn’t enjoy convenience, so we tend to go for frozen food more often that we would like to admit. However, it is important to not make that a habit because over a due course of time, it sure comes with a lot of complications. Once in a while is something, we all understand, however before we made that a lifestyle choice, we need to be aware of what all implications it would have on our health and whether it’s really worth it.
Diabetes: In order to keep the frozen foods fresh starch is used. The starch that is in question here adds taste and texture to the food. Starch is a glucose chain, and our bodies convert this glucose to sugar before it is even digested. The excess sugar increases your risk of diabetes while also causing damage to your body tissues. If it runs in the family, you should try avoiding having frozen foods.Heart Diseases: Another health risk that is associated with frozen or processed food is heart disease. The trans fats that are present in packaged foods increase your risk of contracting heart disease and also contribute to clogged arteries.
Excessive calories: Frozen foods are very high in fat. Fat contains twice the number of calories compared to carbohydrates or protein; this often makes it high in calories. For instance, 1-cup serving of frozen chicken pot pie may contain nearly 600 calories, more than half of which come from fat. Although, frozen foods are marketed to be healthy and nutritious but the fact is they harmful for your body.
冷冻食品在我们生活中相当受欢迎，因为所有人都享受了其便利，所以我们倾向于更频繁地去选择购买冷冻食品，这点是我们必须承认的。然而，重要的是不要去养成这种习惯，因为随着时间的推移，它肯定会带来一些并发症。我们都应该明白，有时候，在我们做出生活方式的选择之前，我们需要知道它会对我们的健康产生什么影响，以及我们的选择是否真的值得。
糖尿病：冷冻食品中含有过量新鲜淀粉。这里所讨论的淀粉增加了食物的味道和质地，淀粉是由葡萄糖链构成的多糖物质，我们的身体在消化食品后将这种多糖成分转化为单糖，过量的糖会增加患糖尿病的风险，同时也会对身体组织造成损害。如果你的家中有类似冷冻食品，您应该尽量避免食用它们。
心脏病：与冷冻加工食品相关的另一个健康风险是心脏病。包装食品中含有的反式脂肪会增加您患心脏病的风险，也会导致动脉阻塞。
过多的卡路里：冷冻食品的脂肪含量很高。与普通碳水化合物或蛋白质相比，脂肪所含的卡路里是前者两倍；高含量的卡路里意味着高热量。例如，冷冻鸡肉馅饼可能含有近 600 卡路里的热量，其中一半以上来自脂肪。虽然冷冻食品在市场上被宣传为健康和营养丰富，但事实是它们对你的身体有害。

The act of freezing doesn't make food healthy or unhealthy—it really depends upon the nutritional content of the food that gets frozen. Frozen fruits and vegetables can be just as nutrient-dense as their fresh counterparts, but frozen foods like pizzas, snacks, and entrees can be less nutrient-dense when compared to frozen fruits and vegetables.
If your food was nutritious before it was frozen, it will still be nutritious after it's thawed. You can't go wrong with plain, frozen fruits, vegetables, meats, chicken, and fish. You can even freeze whole grains.When it comes to preparing and serving a quick meal, nothing beats the convenience of frozen foods. They fit nicely in your freezer, keep for a long time, and they're easy to prepare.Stocking up on frozen foods can also be a great way to save money if you buy them when they're on sale. You can also freeze fresh perishable foods to keep them longer, which is a great way to cut down on waste. But many still wonder whether frozen foods can be a part of a healthy diet.Generally, frozen foods retain their vitamins and minerals and there is no change to the carbohydrate, protein or fat content. In some cases, frozen foods have more vitamins and minerals compared to fresh because fresh foods lose vitamins and minerals over time while freezing preserves nutrients.
冷冻不会使食物变得健康或不健康——它实际上取决于被冷冻的食物的营养成分。冷冻的水果和蔬菜可以和新鲜水果蔬菜一样营养丰富，与冷冻食品，如披萨、零食和主菜相比，它们的营养含量会保持的更好，如果你的食物在冷冻前是有营养的，那么解冻后它仍然是有营养的，普通的冷冻水果、蔬菜、肉类、鸡肉和鱼不会有问题，你甚至可以冷冻所有的谷物。
在准备和供应快餐时，没有什么比冷冻食品更方便的了，它们可以放在冰箱里，保存很长时间，而且很容易准备，如果你在打折的时候购买，那储存冷冻食品也是一个省钱的好方法。你也可以冷冻新鲜易腐烂的食物以保持更长时间，这是减少浪费的好方法。
但许多人仍然想知道，冷冻食品是否可以成为健康饮食的一部分。一般来说，冷冻食品保留维生素和矿物质，碳水化合物、蛋白质或脂肪含量没有变化，在某些情况下，冷冻食品比新鲜食品含有更多的维生素和矿物质，因为新鲜食品随着时间的推移会失去维生素和矿物质，而冷冻食品可以保存营养。

Eating frozen food that has been cooked properly does not affect your health negatively.
It is just food. Freezing does not cause it to become unhealthy.
食用经过适当烹制的冷冻食品不会对您的健康产生负面影响。
这只是食物，冷冻不会使其变得不健康。

There's nothing particularly *wrong* about cold food, it just might not be pleasant.Frozen food depends on how you mean. There are very few foods MEANT to be eaten frozen. Popsicles and ice cream have tons of sugar, obviously, so they should be eaten in moderation. Frozen fruit, you're fine.Frozen foods, as in “that bag of chicken nuggets in the freezer" or similar contain lots of salt, sugar, and preservatives. Minimize those when and where you can.
冷食并没有什么特别的问题，这取决于你的意思。冷冻后的食物不能吃太多，比如，冰棒和冰淇淋含有大量的糖，所以应该适量食用。
冷藏水果，这可以有。
冷冻食品，如“冰箱里储存的鸡块”或类似的食物，都含有大量的盐、糖和防腐剂，尽量减少食用他们。

Fresh frozen vegetables are excellent for you. The idea that canned or frozen food are inferior or lesser quality is not true. The best tasting, most ripe tomatoes don’t go to the grocery store. They go into canned tomato sauce, canned stewed tomatoes and ketchup. Why, because they leave them on the vine to fully ripen because they don’t have to survive several weeks of truck and warehouse transport. Frozen vegetables are picked at peak ripeness and flash frozen right away. So they are probably more nutritious than the ones in the store which degrade from shipping an d storage and less nutritious because they are picked too early.
新鲜的冷冻蔬菜非常适合您。认为罐装食品或冷冻食品质量劣质的观点是不正确的，味道最好、最成熟的蔬菜不会是从超市买的，好吃的会经过速冻加工制成罐装食品或者果酱，为什么，因为这些都是在藤蔓上完全成熟后经过加工获得的，它们不必经历几周的卡车和仓库运输，冷冻的蔬菜在成熟高峰期时采摘，然后立即瞬间冷冻。所以它们可能比商店里的那些更有营养，店里那些蔬菜还可能营养不足，因为它们往往会在成熟前提前采摘。

Your definition for “cold food” is not clear so I'll try to cover as much as I can.First of all, eating anything too cold quickly will stimulate your digestive system, especially your stomach. You may experience stomach ache or even diarrhea as your body tries to get the food out, consequently causing dehydration or lowering immunity in some cases.If you mean some dish that's cooked and refrigerated, you may get bacteria infections. Low temp in the refrigerator doesn' kill germs but slows their growth and reproduction instead. As a result there could be plenty of bacteria on your food by the time you take it out from the fridge and you'd better reheat it in some way before consuming.
If you mean food that's undercooked or not cooked at all, you could easily get sick because of the germs or parasites. Besides bacterias which may get you diarrhea and other sickness, unclean meat may contain parasite eggs or larvae, most of which are tapeworms and roundworms. Eating raw and you may get these parasites living happily in your body, posing great health risks (could be lethal).So in general it's probably a bad idea to eat cold food. Hope this answer helps.
你对“冷食”的定义不明确，所以我的回答会尽量涵盖。
首先，吃太冷的东西会刺激你的消化系统，尤其是你的胃。当您的身体试图将食物排出时，您可能会感到胃痛甚至腹泻，从而导致脱水或在某些情况下降低免疫力。
如果你的意思是一些煮熟和冷藏的菜，你可能会感染细菌。冰箱中的低温不会杀死细菌，只会减缓它们的生长和繁殖，因此，当您从冰箱中取出食物时，食物上可能含有大量细菌，您最好在食用前以某种方式重新加热。
如果你指的是未煮熟或根本没有煮熟的食物，你很容易因为细菌或寄生虫而生病。除了可能导致你腹泻和其他疾病的细菌外，不干净的肉还可能含有寄生虫卵或幼虫，其中大部分是绦虫和蛔虫，生吃它，这些寄生虫可能会在您的身体中快乐地生活，从而带来巨大的健康风险（可能是致命的）。
所以总的来说，吃冷食可能是个坏主意。希望这个答案对你有帮助。

The primary danger is food poisoning. In all cases, cold food has greater risk than steaming-hot just-cooked food, all other factors being equal.Some examples:If you’re eating in China, all raw vegetables are suspect because they will likely have been irrigated and rinsed in unsanitary water. If you’re served a steaming hot plate of the same vegetables stir-fried, any bacteria should have been killed.Whenever you have cold meat out somewhere, whether it’s a sliced ham sandwich from your local deli or meat from a cart in China, you don’t know how long it’s sat out. You don’t know if the server washed his hands after going to the bathroom. You don’t know if a fly laid maggots on it. Among the many risks are Listeria.For instance fruits from reliable sources that you wash/peel yourself, fresh bread, dry foods like crackers, and fresh foods that you cooked yourself and didn’t allow to become contaminated or sit too long at room temperature.
主要的危险是食物中毒。一般来说，在所有其他因素相同的情况下，冷食比刚刚煮熟的热腾腾食物的风险更大。
一些例子：如果你在中国吃饭，所有的生蔬菜都是可疑的，因为它们很可能是用不卫生的水冲洗过的。如果你吃的是一盘热气腾腾的炒蔬菜，这完全没有问题，因为任何细菌都会被高温杀死。
当你在某个地方吃冷食时，无论是当地熟食店的火腿三明治还是中国的手推车上的肉，你都不知道它已经放了多久，你也不知道服务员上完厕所有没有洗手。你不知道苍蝇是否在上面产了卵，其中含有许多风险包括李斯特菌、沙门氏菌和肝炎。
不过，许多食物都是安全的冷食。例如，您自己清洗/剥皮的可靠来源的水果、新鲜面包、饼干等食品，以及您自己烹制且没有被污染或没有在室温下放置时间过长的新鲜食品。

Since frozen foods are often flash-frozen very quickly after harvesting, degradable vitamins can be preserved better than in food that has traveled days to get to a grocery near you.Even local fresh food may be a few to several days since picking, and may begin to break down some of its nutrition. Nothing is better than a fresh picked vegetable/fruit from a garden with well-nourished soil, from plants not genetically modified to withstand transportation. Farm stands and your garden are the best, if the soil is healthy.Freezing is the next best choice.P.S. I’m talking about unprocessed food, not frozen meals and similar.
由于冷冻食品通常在收获后很快就被快速冷冻，因此可降解的维生素可以比运输数天到达您附近的店里的食品保存的更好。即使是当地的新鲜食物也可能要采摘几天，并可能有部分营养物质分解了。没有什么比从土壤肥沃的花园中新鲜采摘的蔬菜/水果更好的了，这些蔬菜/水果未经基因改造也没有经历长途运输。如果土壤健康，你的农场和您的花园是最好的选择，冷冻食品才是下一个选择。
PS：我说的是未加工的食品，而不是经过加工的冷冻食品或类似食品。
