Freezing is a natural preservation process which does not require the use of additional preservatives. Vitamins and minerals are 'locked in' through freezing, while fats, proteins and carbohydrates are unaffected.
The biggest positive for freezing food is that it can sustain for much longer. It travels better, and it maintains nutritional value for longer. Ironically, one of the negatives for fresh food is in the travel time it is likely to lose nutritional value at a much faster rate in comparison to its frozen counterpart. Therefore, frozen food is a real alternative to fresh, that's just as good nutritionally.
