Research results have been reported that this frozen food is actually surprisingly nutritious.

A study from the University of Georgia at the University of Georgia found that frozen vegetables and fruits may be more nutritious than raw vegetables and fruits. Reported by US media Athens Banner Herald.
According to the media, the university's research team focused on certain vitamins and minerals in eight vegetables and fruits. The eight vegetables and fruits are blueberries, strawberries, broccoli, green beans, corn, spinach, cauliflower, and green peas. In order to compare these ingredients raw and frozen, raw vegetables and fruits are stored in a household refrigerator for 5 days after purchase. The nutritional value was then examined and compared to the same frozen food. They found that some vegetables and fruits had higher vitamins A and C, and folic acid content in the frozen ones than in the raw ones stored in the refrigerator for five days.

According to Ronald Pegg, an associate professor at the university, nutrients such as vitamins in vegetables and fruits gradually decrease after harvest. Therefore, frozen vegetables and fruits may have higher nutritional value than raw ones, considering that they should be stored for several days from purchase to eating.
He said:
“Vegetables and fruits are“ living things ”. They breathe and grow old. (Omitted)“ Frozen ”is a natural“ stop button ”. Will keep it "
