Question about frozen and canned vegetables Nutr value..

I don't go that route but I've been told and read that they are as if not more nutritious than fresh. Is this true??

Example for sake of discussion.

Canned tomatoes. Canned off the vine at the source and preserved.

Frozen broccoli. I don't know for sure but preservation is top as well.

Yes, some fruits and vegetables are more nutritious when canned or frozen.  For example,  foods that lose vitamin C  unless preserved.   Of course, fresh food is preferable  but nutrition  loss from storage or transport is minimal.  Preservation is cost effective and conveniently allows for year round availability of foods.

^ Yes.
