I actually learned this, this week. They do not loose nutrients. They have more nutrients than the fresh fruits and veggies at the grocery store. Because the ones that have been frozen were frozen very soon after they had been picked. Therefore, more nutrients. Fresh foods that have been sitting out in the store have been been picked many days previously which they have lost nutrients.
Frozen foods in the store - frozen peas, for example, often have more nutrient value than the fresh product as the time they spent from plant to the frozen state is less than the travel time for "fresh produce" in your store.
Depends where you live, how far this stuff has been trucked, time of year, whether it is in season or not, and so on. Freezing causes very little loss of nutrients. You might be able to find this sort of information on a state, province, or federal health site, such as Health Canada.
I agree with the other poster. You will always lose some nutrients. Heck, you start losing that as soon as you take it off the tree/out of the ground! Freezing, when done properly, doesn't make you lose too much, tho. If you really are worried about losing nutrients from your fruits and veggies, then watch out for cooking them! This kills the enzymes/nutrients - especially Vitamin C.
Hope this helps! God bless!
Any fresh produce is going to lose something, from the time it is picked, till the time it is consumed. The produce that you freeze yourself, provided it is done safely and properly, will have more nutrient value than if you bought the same item in a frozen bag from the store.
I am sure that you can look up the approximate nutrition values on most state or national food sites.
Search for something like 'nutritional values comparison', etc.
Good luck to you.
