However the down side of this is when we rely of canned foods or have canned fruit as a significant source of fruits. This is because the nutrients are destroyed in the canned process. An example of this is shown below. This is what happens to the vitamin C level in canned goods. (it also shows irradiated and frozen effects). Again clicking on the graph should make it larger. You can see that the vitamin C is massively reduced. Furthermore vitamin C is a water soluble nutrient like a large group of additional nutrients. These are called by a number of names such as bioflavonids or phytonutrients..... they make up a large proportion of the antioxidant levels in fruits. Therefore we can theorize that if vitamin C is massively reduced then the bioflavonids are also likely to be significantly effected. Hence canned food is a great treat but you should rely on locally grown fresh fruits for the majority of your fruit intake.

Canning - removes vitamin C and likely many anti-oxidants
