Here's something that's been bothering me for a while.

I know that you're not supposed to boil certain vegetables because they lose some of their vitamins to the water. You're supposed to steam them or cook them in some other way instead.

I often try to get rid of spare vegetables by adding them to something else. Carrots, for example - the nieces don't consistently like carrots (that is, when one does the other doesn't), but they're cheap and we always have them, so I'm always grating them up finely and adding them where they're relatively inconspicuous. This helps bulk out the meal slightly, makes it a little more nutritious, and I get to move some carrots out of the fridge! (You'd think I'd learn and stop buying carrots, but then I see a few pounds of them for a dollar in the dubious produce section, and even old carrots keep. The siren call of carrots cannot be resisted...!)

Now, I've recently started making spinach rice. It's a good way to use up spinach (you buy it, but it doesn't get used that fast!), and it's yummy. You cook the rice same way as always, but when it's almost done you toss spinach leaves and butter (or margarine) on top and let it cook a bit longer. And in the process, I discovered that if you add very finely grated carrots to the rice BEFORE you cook it, and stir it in, the rice turns a pretty orange color, but that's about all. I love it!

Except... do the vitamins go away or not? I know that some of them disappear into the water when boiled, but then the water gets absorbed by the rice, so...? Are the vitamins gone now, or are they part of the rice, or what? (My knowledge of nutrition is somewhat limited, admittedly.)

IIRC, part of the problem is long exposure to heat. If you boil the veggies, they will spend a lot of time in hot water, which will not so much "wash out" the vitamins but rather tear up their chemical structure. (This is less likely to occur in steaming or stir-frying because while the heat is even more intense, the exposure time is a lot shorter.)
So no, they will not become part of the rice - not all of them, anyway. They'll have decomposed.

But shouldn't you also be abe to get that orange colour by adding finely grated carrots towards the end of the cooking? It's a pretty intense colourant after all.

Ah, ok. I suppose you'd have to turn the carrots into juice in order to get the nice colour then. But as long as the nieces eat it, all's well, I guess ;)
