With the change in lifestyle, frozen fruits and vegetables are becoming more and more acceptable to most people, and their taste is no different from that of fresh vegetables. However, many people wonder if there is a difference in nutritional value between the two.
It is widely believed that cryopreservation destroys the nutrients in fruits and vegetables, such as vitamins and minerals, so they oppose the consumption of frozen fruits and vegetables. Some people think that frozen fruits and vegetables can be stored for a longer period of time, which can effectively reduce the frequency of going out to buy, which is very convenient.
Research has shown that the only way to get the most out of the nutrients contained in fruits and vegetables is to eat them directly after harvesting them to avoid the loss of nutrients due to storage and transportation afterwards. However, most people don't have this condition, so nutritionists believe that frozen fruits and vegetables have the same nutritional value as fresh fruits and vegetables. The simple reason is that flash freezing reduces the rate of loss of minerals and vitamins from fruits and vegetables, and processed foods can even be stored in the freezer for up to a year.
In fact, the most detrimental to the nutritional value of fruits and vegetables is peeling and stir-frying, which will destroy minerals and antioxidant vitamins such as vitamin A and vitamin C. In addition, people habitually peel some fruits and vegetables before eating them, but only 5 mm of peel can throw away most of their nutritional value. Therefore, experts recommend that cooking or steaming should be used more often when cooking, or that soup can also retain its nutrients to the greatest extent.
When we buy ingredients in supermarkets or markets, we don't know how long they have been stored in the warehouse before that. Just keeping them fresh in the refrigerator can lose up to 40% of their nutritional value in a matter of days.
Therefore, it is still necessary to always have frozen fruits and vegetables in your daily life. However, it is worth noting that the most important indicator of these frozen foods is "all natural". When purchasing, read the label on the package carefully to make sure that there are no additives in it.
