Is frozen food less nutritious than fresh?

Is frozen food less nutritious than fresh? Does freezing a food make it less healthful?

Believe it or not, freezing food does not destroy nutrients—it can actually help preserve them. Depending on your alternatives, there are times that frozen produce may actually contain more nutrients than fresh. Produce is at its peak, nutritionally, when just picked. The longer it stays at room or refrigerated temperatures, the more its nutrients are diminished.

When produce is frozen just after it is picked (at a plant that is often only yards away from the field), those peak nutrients are retained. If your choice is buying fresh produce picked hundreds (or even thousands) of miles away, your nutritionally wiser choice is the frozen version.
