Do you lose food nutrients when you bake healthy fruits veggies into bread?

I have been baking various whole grain breads with pumpkin, cherry, plum, butternut squash purees. I was hoping I wasn't losing the nutrients of the purees.

Do you lose food nutrients when you bake healthy fruits veggies into bread?
cooking anything makes it lose nutrients, yet sometimes it makes other nutrients more available for our body to utilize. But applying heat makes the food lose nutrients. I should stress the fine point that lost nutrients through cooking does not necessarily mean less nutritious. Take corn, lots of niacin, but none in a form the human body can use. Cook it with wood ash, and voila! a niacin source. This form of corn is called hominy.



Oh yeah, and next time you are at the store, check the lable on a can of regular corn. It tells you that there is so much niacin (vit. B6) in it. But the FDA, USDA allow the false labling. Sure its in there, but we poop it out.
Reply:yes
Reply:Because the fruit or vegetable is enrobed within the dough, the nutrients do not bake out of the bread.



However, I question the puree...it has already been processed (if you buy it) and has lost some of the goodies already.



If you are making the purees yourself, are you cooking the veggies or fruit before mashing? If so, you've already lost some of the nutrients.



Hope that helps.
