change of nutritional value during preparation

Question
Hi!
I like to prepare my potatoes like this: Cut them in small chips and bake them
in the oven at 200(degrees celcius(392fahrenheit) for 20 min. (they get crispy
but not burned or black).
I was wondering if there was a change in nutritional value during this
preparation, and how this would compare to just boiling the potatoes in
water.

I have also been wondering about the same thing in regard to vegetables. Is it
better to eat them raw or is it ok to boil them?

PS
IF you know a website where they discuss these kinds of things a hyperlink
would be most welcome.

Answer
Rasmus,

Baked potatoes will maintain more nutritional value than boiled - so keep doing that.

As far as veggies go, raw is best. If you want to cook them you should steam them briefly and not overcook. Boiling them will destroy and/or remove many of the vitamins and other nutritional components. Much of the good stuff in all veggies is destroyed by heat. Microwaving is no good either.

Hope this helps.
