Does it change?

Is the fibre still good in them?

the nutritional value isn't going to change just by pureeing, and the fiber is still in it. Nutritional values will change when you cook them. Usually, you'll lose some, esp if the food is boiled, but lycopene in tomatoes becomes more usable for people.

are you specifically asking based on cooking foods? Boiling is the worst. steaming or eating raw would be the best. I love roasitng veggies in the oven.

Thanks. Mostly I boil or steam vegetables. I also reheat in the microwave :S

lightly cooking in the micro is fine too. Boiling any veg to death isn't going to be very healthy. Obviously, potatoes need to be boiled till cooked though

Sorry to hijack, but can I ask, if you boil something and then use the water to cook with (ie: to make gravy or stock or whatever) do you still loose more nutritional value than steaming? Just curious really since I steam everything anyway.

I have to admit, I don't. There was a thread about that very thing recently too. You can recoup the lost vitamins by reusing the liquid.
Actually, the other thread was on reusing bean water now that I think of it....

I rarely boil anything. I usually microwave veggies, or roast them....and now grill....which is divine!

yea you'll lose a little nutrients in the water if you boil, It's not that substantial though. but steaming is best. I haven't used my bamboo steamer in a while, but gonna bust it out tomorrow to make some dumplings and veggies.

It really depends specifically which nutrients you are talking about. Yes, the water you boiled them in will come some of the nutrients, but some simply aren't as useable after being cooked, while others are more easily absorbed. Really, if you're getting moderate quantities of all of them in any form, you are unlikely to develop vitamin deficiencies. I wouldn't worry about it too much. Sometimes I eat them raw, sometimes I eat stew that's been slow cooked for hours... I'm still alive and well :P
