I've always been told that frozen fruits and vegetables are not good and cannot be eaten.

Yahoo Diet & Fitness, Rachael Anne Hill, a nutrition expert highlighted five reasons to start buying frozen fruits and vegetables.

Nutrients
Fruits and vegetables sold in the shop normally were in transit for up to two weeks before arriving on the shelves, which can result in them losing up to 50% or more of many vital nutrients. But, frozen fruit and vegetables are grown in peak conditions and frozen, usually within less than 90 minutes of being harvested. This locks in essential vitamins and minerals making them nutritionally the same, if not better than, their fresh equivalents.

Convenience
Frozen fruits or vegetables won't liquidise itself into a pulp or grow a fur coat if not eaten within a few days.

Taste
Fruits and vegetables taste its best when it is harvested at just the right time and be eaten as soon as possible afterwards. Many fresh fruits and vegetables, however, are harvested before being allowed to fully ripen to extend shelf life which can make them tough and tasteless. Freezing takes care of the shelf life side of things so produce can be allowed the extra time needed to develop a really full flavour.

Availability
Frozen fruit and vegetables are available year round making it easier to keep your diet interesting and varied.

Cost
Frozen fruit and vegetables are, on average, 23% cheaper than their fresh equivalents and tend to result in less waste as you can select the right amount for your needs and leave the rest for another day.
