When you cook other foods you change their composition or destroy some of the nutrients. The fibrous cells in veg/fruit break down, for example.
Go by the package for your bread.
toasting bread does NOT add calories if thats what you mean?
the only way to add calories is to top it with something.... yano like butter? ahahahaha.....
We always learning in classes that when you toast nuts and stuff that it decreases the nutritional value because it basically de-natures proteins that are in the nuts naturally. So your body cannot absorb the nutrients in a way that will help it.
When you cook plant products like veggies and fruits it breaks down the cell walls and releases the good nutritive stuff inside the cells so we can absorb them since we have a simple digestive system (not like the fermented multi gut system of cows) that cannot break down the cell walls by them selves without mastication.
But yea I agree with you gi-jane, I dont think that anything happens when you toast bread excpet moisture evaporation
