Frozen or canned -- which is better?

When it comes to fruits and vegetables, which selection is better? In most cases, frozen fruits and vegetables are the more healthy choice, but why is that?

Frozen fruits and vegetables are generally the same as fresh selections of the same foods, except that they are frozen. In general, there are no (or little) preservatives used at all -- because the foods are frozen soon after being harvested.

With canned foods, additives like sodium and preservatives are commonly used since there is no preservation method in canning really. In addition, the taste of "fresh" fruits and vegetables sure beats the taste of "dead" foods like those that are generally canned.
