We are a produce wholesaler that sells to schools. We have been asked to do a presentation comparing yield and nutrition on fresh vs frozen vs canned. Can you help me find any data?
There is a food buying guide for child nutrition programs from USDA which you can access at http://teamnutrition.usda.gov/Resources/foodbuyingguide.html . Click here to see two references regarding nutrient content of fresh vs frozen vs canned. There is also a summary of these studies which you can access here. I hope this helps.
