If you are worried about what you eat every day, and particularly you tend to focus on the different qualities and nutritional properties that you tend to bring the food you eat in your daily diet, it is quite likely that at some point you have raised whether foods and products frozen foods retain all their properties and benefits. Or if they lose them.
As many statistics show, the number of people who opt for frozen foods, and recipes -for example- that have already been prepared before and frozen afterwards, is increasing. It is a very useful alternative especially for those who do not have a lot of free time, and they need to thaw a certain food and cook it or consume it quickly.
What is a frozen food? What are its advantages?
Basically we could define frozen food as a food that has been subjected to an intense application of cold, helping to prevent the deterioration of the product and stopping the various bacteriological and enzymatic processes that could take place in it when it is at room temperature or preserved in the fridge.
That is, the main difference between a fresh food and a frozen food comes from that, precisely, the latter has been subjected to an extreme decrease in temperature, which produces the freezing of water, which is its main component.
This offers interesting advantages, since increases the useful life of the food , at the same time that, as indicated at the beginning of this section, the maintenance of its microbiological quality is ensured. While, in addition, Almost no virtues and organoleptic qualities are altered .
In addition, it is common that they are already peeled, washed and cut, especially if they are frozen vegetables. So its use in the kitchen can be much faster and easier.
Is it true that frozen foods lose properties?
Unlike what is mistakenly thought, many nutritionists agree that, in most cases, Natural products that have been frozen may contain a greater amount of vitamins and minerals Compared to those who have been refrigerated later, even though the latter are fresh.
Why? Fundamentally because frozen natural foods tend to be processed, and therefore frozen, almost immediately after they are harvested.
This means that, in short, most of its nutritional qualities are maintained. And if we compare them in fact with the same fresh natural food that has been refrigerated days after its collection (for example when buying it and bringing it home), it is probable that these have been better preserved in the frozen food.
However, although frozen natural foods retain their properties, they do not mean they are better than their fresh option. It is true that they can contain and maintain all their nutritional qualities if they have been frozen rapidly after harvesting. But in most cases the latter is very difficult to find out, so we will never be completely sure.
So, the natural and fresh option will always be above your frozen alternative , since we will ensure that it is in its optimal period of consumption and will contain most of its essential nutrients.
Not all frozen foods are healthy ...
But we must be careful to think that frozen foods are better, or that they have the same benefits always .
We must clearly differentiate between those frozen foods that are natural (such as vegetables or fruits) or that come from slaughter (such as meat or fish), which preserve their nutritional value, flavor and freshness, from precooked foods or frozen preparations.
Usually, precooked foods or frozen preparations have a greater amount of fat and additives , so from a nutritional point of view are not always highly recommended. We could mention products like pre-fried potatoes, frozen croquettes or lasagna.
